Same or Different Sort
Hold up two objects and ask: are these the same or different? Sort a pile of household items by one property - all soft, all round, all the same color - then change the sorting rule each round.

Pick up pairs of objects and ask "same or different?": then sort a pile by one property at a time, changing the rule each round. Practices comparison and flexible categorisation through hands-on sorting.
How to do it
- Gather a mixed pile of 8-12 household objects. Start by holding up two objects and asking "are these the same or different?"
- Accept whatever your child says and ask "what makes them the same / what makes them different?" There's often more than one answer.
- Now introduce a sorting rule: "Let's put all the soft things in one pile and all the hard things in the other." Sort together.
- Once sorted, change the rule: "Now let's sort by color: all the blue things here, everything else there."
- After two rounds, ask: "Can you think of a new way to sort them?" Let them pick the rule.
What you need
- Mixed household objects
Signs it is working
Your child sorts a group of objects correctly by the rule you named. They suggest a sorting rule on their own when invited. They can sort the same objects a second way by a different rule, showing flexible thinking rather than assuming one sort is the only one
If it is not quite clicking
Same-or-different comparisons aren't landing: Start with two obviously identical objects ("these are the same") and two obviously different ones, and just practice the vocabulary. Sorting by a rule is hard: Work on one sort at a time and physically help by pointing to where each object goes. Changing the sorting rule between rounds is confusing: Keep all objects in one pile and re-sort from scratch rather than trying to re-sort from the previous arrangement: a fresh start reduces confusion. Two-rule sorting (the extension) is too hard: Return to one clear rule and call it done
Make it yours
Younger (2-3y): Focus only on same/different with two objects; skip the sorting step; use identical vs very different pairs. Older (5-6y): Try sorting by two rules at once (soft AND blue); introduce "not" as a category ("things that are NOT round"); the rule-change element is the key challenge at this age. Sibling version: One sibling names the sorting rule, the other does the sorting: then swap.
