Lesson 1: Math is MineMPP.3

I can…

I can describe the ways we are all doers of math, and compare my math story with a classmate's.

Key words

• doer of math — Anyone who uses math. That is all of us.
• math story — What you have done, felt, and learned about math.
• strength — Something you do well and can share.
• decompose — Break a number or shape into smaller parts.
• estimate — An answer that is close, found without exact work.

Steps

1. The Ferris wheel has 20 cars, and about 4 people fit in each car. About how many people can ride at one time?
2. I count the cars: 20. Then I estimate how many riders fit in one car: about 4.
3. I do not count every person — an estimate is a reasoned answer that is close enough to be useful.
4. 20 × 4 = 80, so I would say “about 80 people.”
