Question types: Balance the scales

Rule: Balance scales

Balanced scales hold the same weight on both pans. The same shapes weigh the same.

Use one scale to find what one shape weighs, then put that into the other scales.

Example: ● ● weighs the same as ▲, and ▲ the same as ■ ■ ■ ■: so one ● weighs the same as ■ ■.

Watch out: If you take something away, take the same from both pans, or the scales tip.
