Fractions
Different-looking fractions can be the same amount. 2/4 is exactly 1/2. Every fraction has one true home on the number line.
Pizza, recipes, sharing time. Fractions are everywhere.

Common sticking points

- Another is making 'equal' fractions by adding the same number to the top and bottom. That moves the fraction. Multiplying both keeps it in place.
Try this together
Cut something shareable (toast, an apple) in half. Then cut each half again. Ask: is your share bigger now, or the same? Why? (2/4 of the toast is still half the toast.)
