Six pages of story problems that ask about how many or about how much, each with four answers, A to D, as on a multiple choice test. Under every story an Estimate line asks for the two numbers rounded to the nearest ten and the estimate, so students show how they chose. Page 1 is adding and starts with a worked example: 38 red apples and 21 green apples are about 40 + 20 = 60. Page 2 is taking away, page 3 is how many more, how many fewer and a missing part, and page 4 is cents and inches. On page 5 the choices are number sentences: students circle the best way to estimate, then write the estimate. Page 6 mixes every kind. The wrong answers are the tens children get from common mistakes: dropping the ones (30 + 20), rounding one number the wrong way, or adding instead of subtracting.
Do the example on page 1 together: find the two tens each number is between and ask which one is closer, then add the tens. After a page, pick a wrong answer and ask how someone might have got it; most of them come from a real mistake. Page 5 works well as a talk: why is 50 + 30 a better way to estimate 47 + 31 than 40 + 30?
Ask about how much at the store: a juice costs 57 cents and a banana 31 cents, about how much is that? Round each price to the nearest ten and add. Then cover the choices on a problem and ask your child for the estimate first, before looking at A to D.
