For children who can count the objects in each small group one by one. Each ● is one object of the same size. Compare how many objects there are, not how much space a group takes up.
How to play
- Ask your child to point to each ● in group A, then group B, counting each object once.
- Match one object from A with one from B, or compare the two counts. Ask which group has an object left over before choosing.
You will need
- No materials needed for the screen game; nine large blocks are optional for matching on a table.
Each ● is one equally sized object. Group A: ● ● ● ● ●. Group B: ● ● ● ●. Compare the number of objects. Which statement is true?
Well done! That is right. Group A has five objects and group B has four. After matching four pairs, one object remains in A, so A has more.
Not quite yet. Match one ● in A with one ● in B. Which group has an object left over?
Answer and explanation
Group A has five objects and group B has four. After matching four pairs, one object remains in A, so A has more.
Make it easier
Cover the options and match the objects in the two groups one at a time; then look for the leftover object.
Make it more challenging
Ask your child to explain how many objects each group has and why the groups are not equal.
If you use blocks, choose pieces too large to swallow and stay with your child during play.
