5 r2 vans is not an answer: 4th grade math lesson

What this lesson shows

Fixes a mistake

The leftover 2 kids still need a van, so it's 6 vans.

The worked example

The lesson works this one step by step: 22 ÷ 4. Then your kid tries one like it on paper.

The steps

Divide
Read the question again
Everyone must fit: add one more

Helping at home

Divide first, then read the question again. Ask "Does everyone have to fit?" If so, the leftover needs one more. The answer is a whole number with its unit, never with an r.

If your kid gets stuck

Does everyone have to fit?
