Weights lie on the left and right side of the scale.
You decide whether the scale is balanced or whether one side is heavier.
Here's how:
1. Add up the weight on the left side.
2. Add up the weight on the right side.
3. Connect the row to the scale that matches.
The drawn line shows the solution.
Example
- Balanced
- left heavier
- right heavier
For parents
What does this exercise practice?
Add and compare weights and understand the balance scale as a model for smaller, greater and equal.
Common pitfalls
When comparing, children often forget to convert, for example that 1 kg equals 1000 g. Convert both sides to grams first, then compare.
How to practice at home
Build a coat-hanger scale and hang small objects in bags until both sides hang at the same level.
