 Article posted October 3, 2013 at 02:13 AM GMT • comment (3) • Reads 697 I asked my dad about how he uses estimation. I asked him questions like how do you use it? Why do you use it? When do you use it? What do you use it for? And what happens when you estimate wrong. It's very important to know how to estimate right because if he doesn't get around the price and estimates a little low and the customer accepts, you've got to do the job for that amount. If you estimate too high and they still accept you do the job and you keep the extra money. That's why you've got to be close to the price.

 Article posted October 3, 2013 at 02:09 AM GMT • comment (3) • Reads 81 My dad uses estimation when he does the bills, estimating time, and estimating how long something is going to take. He uses it for estimating distance like how far will it take until he reaches his destination, and estimating how long something is going to last.

 Article posted October 3, 2013 at 02:05 AM GMT • comment (4) • Reads 102 Me: Mom, how do you use estimation? Mom: Well, here are some examples. I use it for knowing how long to put cheesy chips in the microwave, how much work I can get done in an hour, how much food our dogs need when we go on vacation, what size the load of laundry is, etc. Me: But why do you use estimation? Can't you just use a tool to measure things like your examples? Mom: I suppose, but estimating can save time, and can... Ummm... Give you a better result when you can't get an exact measurement (when that's not possible). Overall, estimation helps you be more efficient! Me: Wow! Thank you so much, Mom! Mom: You're very welcome. Article posted October 3, 2013 at 02:05 AM GMT • comment (4) • Reads 102
