Rabbit sorts pretend buttons by color, while Fox sorts the same buttons by shape. Both can be sensible if the rule is clear. Choose one rule and apply it consistently.
What you will discover
- Sorting puts items into groups using a chosen rule.
- The same objects can be sorted in different useful ways.
English vocabulary
- sort
- phân loại
- group
- nhóm
Let’s play
The rule is “red things.” Which item belongs?
- A red triangle
- A blue circle
- A green square
See the explanation
Color is the rule, so the red item belongs even if its shape differs.

2. What should stay consistent during one sort?
