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 mathematical thinking — which is everyone, every day.
math story — Your own history with mathematics — what you have done, felt, and learned so far.
strength — Something you already do well and can share with others.
decompose — To break a number into parts that add, subtract, multiply, or divide back to it.
estimate — A reasoned answer that is close enough to be useful, without counting every one.
Steps
The Ferris wheel has 20 cars, and about 4 people fit in each car. About how many people can ride at one time?
I count the cars: 20. Then I estimate how many riders fit in one car: about 4.
I do not count every person — an estimate is a reasoned answer that is close enough to be useful.
20 × 4 = 80, so I would say “about 80 people.”
