True or false equations

What the equal sign means: both sides are the same amount. Your child decides whether number sentences like 8 + 5 = 7 + 6 are true or false.

How to help

Work out each side on its own. If both sides make the same number, the sentence is true. If not, it is false.

Watch for: Thinking = means “the answer comes next,” so 8 + 5 = 8 + 5 looks wrong. Working out only the left side and ignoring the right. Calling 3 + 4 = 4 + 3 false because the numbers are in a different order.

At home: Make both sides with blocks: 4 + 3 on one plate, 5 + 2 on the other. Are they equal? Try a pair that isn't.
