More, Less, Same
Compare groups and balance
What your child practises
Comparing groups by matching them one to one, seeing equal as balanced and unequal as unbalanced on a scale, and reading simple picture graphs.
Saskatchewan Curriculum outcome: NK.5 · comparing quantities to 10 using one-to-one correspondence
How we explain it
Children can open this short lesson before they practise.
- Match things one to one.
- The group with extras has more.
- If none are left over, the groups are the same.
Example: There are 5 cats and 3 dogs. Which group has more? Match each dog to a cat. 2 cats have no match. Answer: The cats
