Equal Shmequal
by Virginia Kroll
Mouse and her animal friends want to play tug-of-war, but the teams keep coming out uneven. Using a seesaw, they figure out what "equal" really means.
Why it's useful
A great introduction to the equal sign and balance.
- Equal means same value. Not just same number of animals, but same weight.
- Balancing. The seesaw shows two sides being equal, like an equation.
- Fair teams. Kids reason about combining different amounts.
Try it in class or at home
- Balance it. Use a pan balance and cubes to make both sides equal.
- True or false. Is 3 + 4 = 5 + 2? Is 8 = 4 + 3? Discuss.
- Make fair teams. Give each animal a weight and split them into equal teams.
