Sorting in Two Ways
Goal: Sort a collection using one rule, explain the rule and sort it again using a different rule.
Do together
-
Choose a rule
You need: Six to eight large paper shapes in two coloursTear the paper yourself into large rough circles and squares, making both shapes in both colours. Let your child put things that belong together into groups. Ask what their rule is. If they need a start, suggest grouping by colour.
-
Same pieces, new groups
You need: The same paper shapesMix the pieces again. If your child sorted by colour, try sorting by shape now. Point to a red square and notice how it belongs with red pieces under one rule and with squares under the other.
-
Find my rule
You need: The same paper shapesStart two groups without naming your rule. Offer your child another piece and ask where it belongs and why. Then swap roles. If a piece seems out of place, ask them to check it against the rule and move it if they wish.
Talk about it
- What makes these pieces belong together?
- How else could we sort the same pieces?
- Where would this piece go under your new rule?
