Math Module 1 Letter In Module 1 we learned about graphs,sequences, exponents,probability,problem solving and order of operations.
For sequences, we figured out patterns and did math magic ticks. We would study the first four terms in a pattern and then would try to figure out what the 10th,20th and 100th terms in the sequence were. We would write an algebraic formula to figure out any term in the sequence. The math magic tricks were really fun but challenging. You would pick a number perform a couple of operations, then the result would be your original number or a different number. We would do the trick several times and if the results are a different number than the original number, it should be the same number every time you solve it. Then we would explain steps using squares and circles and algebra.
For probability we did experiments and online simulations. We did a bunch of different experiments using dice, cards and then came up with our own experiment. For my experiment I used toothpicks and a compass. I tossed 2 toothpicks with one end cut off over a compass 160 times and recorded which way they pointed closest to. The name of my experiment was Which Way? The theoretical probability was 40 for North, South, East and West. The Experimental probability was 44 for North, 40 for South, 43 for east and 33 for West. We also used a probability simulation online where the computer rolled a dice or drew a card as many times as we wanted it to and it made a graph and fractions.
