Think first4 cups of flour, one 1/2-cup scoop

A recipe needs 4 cups of flour, and you only have a 1/2-cup scoop. How many scoops?

Decide first, then press Next. Fill one cup first, then all of them.

4 cups of flour, measured with a 1/2-cup scoop: four bars labelled 1 cup and one tinted half-cup piece set apart. Each bar is cut into 2 halves, marked 2 halves, then numbered 1 to 8, with 4 ÷ 1/2 = 8 underneath. The last step shows 2 cups of milk and a 1/3-cup scoop.

The big idea

4 cups ÷ 1/2 cup = 8 scoops: each cup takes 2 half-cup scoops.
