 Article posted May 23, 2012 at 12:17 PM GMT • comment • Reads 34 This week in geometry we started a very fun and new topic that is known as right triangle trigonometry. This has to do with finding out the lengths of the sides of a right triangle, as long as you have one of the angles and on of the other sides. We can use sine, cosine, and tangent to get these sides. In order to use sine, we have to know either the opposite side and or the hypotenuse and the one we don't known has to be the unknown. The same goes for cosine, which uses the adjacent side and the hypotenuse, and tangent, which uses the opposite side and the adjacent one. These can all be abbreviated to SOH, which means sine, opposite, hypotenuse, CAH, which is cosine, adjacent, and hypotenuse, TOA, which is tangent, opposite, and adjacent. I really think that I am going to enjoy, and like, this unit because it is something that I have done before. At my old school we had a huge unit on SOH, CAH, TOH and we had this project, where we had to find the height of a building, a tree and a car, using only the SOH, CAH, TOA method. I really enjoyed that project. Anyways, I am really sad and excited that school is coming to a really quick close. The days seem to be flying by, and I really should start studying for exams! However, I am so excited to spend summer in York, I am looking forward to going to the beach, getting my own job, and relaxing without any school, except for the occasional AP english classes.

I turned it in on time, of course, and I hope that I get a pretty good grade, but I have no idea what is going to go down on that project because scratch was really hard for me to work! Every time that I would save my project, it would change itself, like it had a mind of its own. Also, when I tried to make it go one forever, but every time I tried doing that it messed up and started over halfway through my project. Anyways, we have been learning all about area formulas, especially those having to do with circles. My favorite one is finding the area of a sector, which is the angle of the sector over three hundred sixty times pi, radius squared. I like this formula because it makes sense, and that means that I do not have to memorize it, I just have to know what a sector is and what part of the circle that it contains. Another thing that we are having in geometry this friday is a quiz! This quiz is going to be on everything we have been doing for two weeks. I definitely am going to have to study for this, but I think that I am going to go into Ms. J's room tomorrow at lunch because I am going to work on the sheet we got in class and the homework, if I have any questions that I will definitely ask her. Overall, I like this unit, so far, but I am not sure I am going to get a great grade on this quiz coming up. Another thing that I have to do in the geometry class is to pick up my english project, it has been sitting in that classroom for so long, but I am going to try to remember to get it today.

The first special triangle that I mentioned have three different sides that can all be found if you known one length of the triangles side. I remember that this is the triangles with three different side lengths because it also has three different angle lengths. The next triangle that we looked at was the 45-45-90 triangle which was interesting, and the triangles that I personally liked better, because the rule was easier to remember. Both of the legs equal the same number and the hypotenuse is the leg number times root 2. I also like this triangle better because I can always picture half of a square, so it is easier for me to remember. Another aspect of geometry that I becoming exciting is our scratch projects. So far I really like where my project is going, in fact I am almost done. My tessellation object looks like a dove, which is really cool. Unfortunately, very suddenly after I had been working on it for a while my main sprite disappeared and I do not know what happened to it. It seems to be invisible even though I did not tell it to "hide". I am definitely going to go into Ms. J because that could ruin my whole project. I am also looking forward to seeing all of the other projects that people will hopefully show to the class. The more and more that we get into these special triangles and finding the areas of objects, the more complicated the math seems to get. I think that this would be another reason that I could use to go see Ms. J at lunch tomorrow. Article posted May 8, 2012 at 09:25 PM GMT • comment • Reads 61

Not a lot has happened since the last blog that I posted, but I will try to describe everything that has happened. So, today, Monday, we took a binder quiz. This was definitely the WORST binder quiz that I have ever taken. This quiz has taught me that I definitely need to start getting more prepared for geometry class. I think that I can do this by putting all of my papers in the back of my binder, and, in my planner, I can start writing down the dates of when we get worksheets. Also, I need to keep my notes in one section, not in my binder, my backpack and my notebook. Dates are also super important and I need to stop slacking off on writing dates to everything that we do, get, take notes on, and do homework on. If I do these two things then next time we take a binder quiz I am really aspiring to getting a 100%. We have also started a new topic in geometry. This unit is all about perfect squares and finding the square roots of different number. This is definitely not my favorite topic. We have not doing this in algebra yet so I am getting very confused. I think that I am going to go in to Ms. Jovanovich at lunch time tomorrow to get some extra help. This includes using pythagoreans theorem to find the different sides of triangles after learning one or more of the other sides of the triangles. Pythagoreans theorem is known as a squared plus b squared equals c squared. I really like using this theorem because it is simple and is ver helpful when one wanted to find the different measurements of a triangles sides. Another thing that we are going to be tested on is our ability to conjure up perfect squares from number all of the way up to twenty. Next class we are going to have a "mad minute" on them, so that is another thing that I am going to do for homework. Article posted April 30, 2012 at 01:41 PM GMT • comment • Reads 43

This is my first time forgetting to do so, I think, so I am very disappointed in myself. Anyways I am doing it now and I am going to talk about translations and the the test/quiz "quest" that we took last friday. First of all, since we have gotten back from break and before break we have been working on translations. I really like translations because there are no proofs involved with them and also because they are very straightforward. And, even though they can get tedious at times, I feel like I am doing the problem right and I generally feel confident doing these problems. My favorite translation would probably be the refection. At first they were the hardest, for me, because the problems that had a equation were very confusing, however, after going into see Ms. Jovanovich I fully understood how to do them and they became fun. My least favorite translations are known as dialations. These were confusing at first because I always though that I just had to dialate their sides and I forgot about the angles. Anyways, they are just confusing for me. However, the dialation on the test is one that I feel that I did good. Now, the "quest"... I think that this was definitely the best, in terms of hardness and easiness, test that I have ever taken in geometry. I think that I got all of the drawing question write, however, there was one multiple choice question that I think I got wrong. That still means that I could have gotten a good grade overall though.

 Article posted April 3, 2012 at 01:09 PM GMT • comment • Reads 44 This week in geometry we started working on a new chapter called transformations. I like this chapter so far because it seems kind of easy, however I am sure that it will eventually get harder. So far we have learned about transformations in class, which was good. Next class we are all looking forward to learning about rotations. Another thing that we recently started looking at in geometry was the program scratch. We are going to be doing a project with tessellations and I think that will be kind of fun to do. At my old school I took a class where we worked with scratch for about two months, so I am not great at doing a scratch project, but I can definitely get around okay. Hopefully this project will give me an extra boost this quarter, I am aiming for another B or higher. Tennis has also been starting up this week, which is really exciting. I still don't know if I made varsity or if I am on junior varsity. I am really hoping that I am going to be on Varsity, but you never know, so I am keeping my hopes kind of low. Other than stressing about varsity or junior varsity, tennis has been really fun and I enjoy playing a competitive game with my friends.

I think that I need to get more sleep, but there is no time. I am starting driver's ed. today and it goes until nine... I'm going to be tired tomorrow too. Anyways I'm sure everyone is tired today, after all it is a monday. I already can not wait for break where I can just relax with hopefully very little homework. So far this week, in geometry we have done a lot of revision, which is great because I definitely needed some explaining on the past homework assignments. I think that all of my major questions were answered, but I really need some more experience with proofs in this unit. Maybe this next homework assignment will give some practice on proofs, but I am not positive that it will. I think that our next test is coming up soon too, so I better start studying. Today, at the end of class, we got our geometry tests back and I was kind of pleased with mine. I was fine with everything, except the short answer on the median problem. That was kind of difficult for me because I thought that making the base slope perpendicular would not work and it turns out that it was the correct answer for slope. So, that is too bad. I am also looking forward to getting my poster project back because I really could use a good grade now and I think that the poster project will really help me out.

 Article posted March 18, 2012 at 02:24 AM GMT • comment • Reads 38 This week in geometry has gone pretty good. I am starting to raise my grade up from a C to a B, which is great! In class we are just starting our unit on quadrilaterals, we are learning all about the different characteristics and definitions of squares, rectangles, rhombuses, parallelograms, trapezoids, isosceles trapezoids and kites. I really like this unit because of the shape aspect. I think that, in geometry, what really trips me up are the proofs. Sometimes I am confident in them and on other days I get them totally wrong, which is really confusing. Hopefully, in this unit there will be no confusing proofs for me to mess up on. We also took a binder quiz this previous week and I think that I did okay. There was one question that threw me off, which was the first one, I could not find a worksheet from January 31 anywhere, but at least it was just one question. If that was the only question that I got wrong than I still would have ended up with a ninety, which is okay. Another thing that I am looking forward to in geometry is getting our grades back for the poster projects that we did a while back. I really enjoyed making my poster and I honestly think that I included everything on the rubric and I did six shapes so I am very hopeful for a good grade. I check powerschool about five times a day for my geometry grades, so I can definitely say that I don't have it back yet. Bye, until next week!

 Article posted March 6, 2012 at 04:23 PM GMT • comment • Reads 39 Today is my birthday! I am so excited. Today in geometry we had a test and I feel extremely confident about the multiple choice, I would be surprised if I got more than one multiple choice question wrong. Also, I am not sure how the long answer question went, I feel like I did it wrong, because I did not know how to do it. However I feel like I did not write the equation right at all because I did not know what the slope was, hopefully I did get it right though, my fingers are definitely crossed. Another question was the indirect proof, which I read over and felt like I got right, I just hope that included everything that was supposed to be included. The coordinate proof was really good though. I think that my hand writing and organization of the proof was correct and my answer makes total sense. Overall this test went okay, if there was one thing that I wish I had studied more, it would have been the second homework of the year, working with finding the slopes of the altitude, medians etc. Another interesting thing that has been going on this week has been the visits from the Neasc people. I haven't really noticed them, as they are so quiet, however everyone around me says some of them are mean. I don't know if this is true, but from what I've seen, it is not. Also, this week is a four day week, which is fantastic because I feel like I need a treat, it will be like a late birthday present! Article posted March 6, 2012 at 04:23 PM GMT • comment • Reads 39
 Article posted March 4, 2012 at 07:19 PM GMT • comment • Reads 34 This week, in geometry, one of the main things that I focused on was the poster project that was assigned.The line of a triangle that I got was a perpendicular bisector. The concurrent point of this line of triangle is called the circumcenter. The title of my poster was called "I'll Meet You Right in the Middle" because the perpendicular bisector hit the middle of a segment and it hit the side of the right angle. I really liked this project because it included a lot of drawing and not as much writing. I really like being able to follow certain instruction and being able to cross them off a list. I think that I did a really god job on this project. I did everything that was on the list really well and I really liked my title too. Another thing that is coming up in our geometry class is the next chapter test, chapter 6. After doing parts of both the chapter review and the chapter tests. I was able to understand the the range of information that we are going to need to know. The only question that I was caught up on was number fifteen on the chapter test, we had to use indirect reasoning and I did not exactly know how to do that, even after looking back on the chapter where is occurred. I think that I will have to see Ms. Jovanovich on Monday to clarify that matter. Otherwise, I feel very confident in the topics and subjects we covered. However there is one main thing that I am worried about for the test, and that would be coordinate proofs. These are definitely my least favorite type of proofs because I am kind of a messy person and it is hard to organize my work exactly how it should be. Luckily, in this chapter, we also came across indirect proofs, which are my favorite proofs, probably because there is a wide range of what you can say. Overall geometry is going good.

So, I was rushing around in the morning until I groggily realized that it was friday, and I have two full days to do my homework. This weekend I am super excited because my friend, who lives in Concord, New Hampshire is coming over. We might go to the dance this weekend, but I am kind of scared that she will get scared of some of the "dancing" that goes on at our dances. If we don't go to the dance than we will probably go to the movies or something. Also, this weekend, I am going to play tennis for about three hours and I am super excited for that. I really want to make the tennis team, which is why I am practicing for three hours. This week in Geometry, our class was told to comment on two different scratch posts from two different people. I commented on Marissa's and Hannah's posts because they both posted fun games that I got to try. Article posted February 10, 2012 at 02:01 PM GMT • comment • Reads 69

Last week our class did not have an assigned blog so it is good to get into the swing of things again. Exams are over an I am happy in every class except geometry. I always have in between an eighty and a ninety and I do not know why I always have such low grades. I studied for this class and I thought it went well... Anyways, today, in class, we reviewed formulas for a line and for me it was brand new stuff that we have not talked about in algebra yet. I am going to have to review a lot I guess. I feel confident because I started studying the formulas in algebra, the class after geometry, however, whenever I feel confident in this class I usually end up doing badly. In our weekly blogs this week our class was told to look up different scratch programs, put down the link, and say why we liked a certain video or program. There were two videos that I especially liked when I was on the scratch website. The first one was called "how to make a duct tape rose pen". This video shows how one can obtain a duct tape rose pen with two colors of duct tape and a pen. I liked this video because I enjoy art (usually) and this seemed like a really pretty project. Also I did not know that you could teach something on scratch. [LINK] The second video that I enjoyed was a game called snake eyes. This game had a pair of dice that one could role and whoever got the higher dice number, the computer or the player would win. You could also type in how many rounds you would want to play. I liked this video because it was an interactive game. I also enjoyed the music that went along with this game. [LINK] Article posted January 23, 2012 at 09:25 PM GMT • comment (1) • Reads 47

I was extremely careful on this test, double checking everything and I felt pretty confident coming out of it. The only two aspects of the test that I had some trouble with was question number nineteen. This question had to do with finding the measures of angles in an isosceles triangle, but there were two variable, which is what made this particular question difficult for me. The other aspect of the test that was small, but hard was the very last justification on the proof, or the last problem on the test. Other than those two problems everything went smoothly and I am really hoping for a good grade on that test and this blog so that I can have a B to go home on my report card. Also, hopefully, I will get a good grade on the possible binder quiz that our class will probably take on Friday!!! Other than that midterms are coming up. I am not too nervous, because I have been studying, but none the less they are kind of scary. The only midterms that I am worried for are the Biology midterm, because we cover so much information, the geometry midterm, because some of our material does not sink into my head, and the english midterm, because we have to write an essay and my grammar and spelling is not great when I am being rushed. Other than that german should be easy, as well as algebra and health because we are allowed to use our binders while we take the midterm. Anyways happy MLK day to everyone next Monday. Another problem that I am coming across before midterms is how to study. There are so amny different ways and I am trying to do them all. Re-read the book, redo the homework, and talk to friends. On monday I am going to a study group so hopefully, that will help. Article posted January 11, 2012 at 09:16 PM GMT • comment • Reads 63

I have made a bunch of new years resolutions, one of these includes me working harder in geometry, as it is the one subject where I am kind of struggling in. Luckily this week in class and the week before vacation were both weeks that I really enjoyed, to the extent of liking math.The ASA postulate, AAS theorem, SSS postulate, and SAS postulates were all some of my favorite postulates and theorems that we have used so far. Another "reason" that we learned how to use this week was CPCTC, which can be a justification in proofs for proving unknown sides or angle congruent. This reason can only be used if we know that the two triangles are already congruent. Also, this week, we had a quiz on all of the postulates and theorems that I had previously mentioned in this blog. The quiz was also and proving triangles congruent. One of the new ways that we were recently taught to do proofs was called a flow proof. Flow proofs are similar to table proofs, except they need more space, are contained in drawn boxes, and you can make the proof connected in any way using lines. In this most recent quiz we had to do two flow proofs. The first proof was kind of easy for me, but the second one was slightly harder because it involved more steps. Overall this test was pretty good and I felt pretty confident going in and coming out of it. Hope fully I got at least a B- on it. I am crossing my fingers! Until next week!

Finally, today, our class turned in our geometry projects. We first presented our projects, to the whole class then we walked around everyones table to view their projects. We voted on the project with the best theme, the most creative, most earth friendly and the 'other' category. The 'other' category was one that we could make up and personalize to someone who we felt deserved a reward. All of the winners of these categories will receive extra credit, and I'm pretty sure a lot of people want the extra credit, not that anyone really needs it. My favorite project, other than mine, was Livy and Hannah's, their project was called 'Candii Landii'. It had tons of bounces and their decorations were great, with real candy and a lot of glitter. I also liked their name, 'Candii Landii'. Exams are coming up two weeks after break! This is the first time I am going to take exams, or midterms, in this case.I have to study for two math classes, so that will be interesting, for these classes I am definitely going to get extra help. I think I can easily study for Algebra 1, but with Geometry the extra help is definitely needed. I am going to take Ms. Jovanovich's help class and just review for twenty minutes a night on the topics we have covered so far. Biology will be easy to study for, but it will take a long time to go over all of the topics, so I will probably get together with friends to study, in order to make make the long hours more useful. For english exams I believe that we are going to write an essay and be tested on vocab., I am mostly going to use flashcards to study the vocab. I will also use flashcards for german class. I am going to designate two seven hour days during vacation to study, this way I can relax on the other part of my vacation. bye! Until next year!!!
