## LET’S BREAK IT DOWN!

### Make 2 equal shares of a circle.

You have a pancake. It's in the shape of a circle. You can share your pancake fairly by cutting it into equal shares. You cut a line straight down the middle. There are 2 pieces. The equal parts are called halves. 2 halves make 1 whole.

You cut a pancake into 2 parts. How can you tell if your pieces are equal shares? Stack one piece on top of the other. They are exactly the same. The 2 pieces are equal shares.

### Make 4 equal shares of a rectangle.

You have a waffle. It's in the shape of a rectangle. You can share your waffle fairly by cutting it into equal shares. You cut your rectangle into 4 equal parts. 4 equal parts are called fourths. 4 fourths make 1 whole.

### Find if the shares are equal.
