What children learn in Level 30
- In a story, the remainder needs some thought. Say 250 people need vans that seat 12. 250 divided by 12 is 20 with 10 left over.
- Those 10 people still need a ride, so we need 21 vans. Here, the answer goes up by one.
- Say a baker has 250 cookies and fills boxes of 12. The answer is 20 full boxes, because the left over cookies don't fill a box.
- And if the question asks what's left, the answer is the remainder itself: 10 cookies.
- So always read the question again before you answer. What does it want to know?
