Odd or Even
Determine whether a group of objects (up to 20) has an odd or even number of members
Suggested ages 7–8
Learning journey
Your child is mastering larger numbers — learning to read, write, and work with numbers up to 1000 by understanding how hundreds, tens, and ones work together.
Evidence of understanding
- Pair objects and determine whether there is one left over (odd) or not (even)
- Count a group by 2s to determine if the total is even
- Write an equation to express an even number as a sum of two equal addends (e.g. 8 = 4 + 4)
Assessment prompt
If Odd or Even has a group of 14 objects, can they tell you whether that number is odd or even — for example by pairing them up to see if any are left over?
