Odd or Even

Determine whether a group of objects (up to 20) has an odd or even number of members

Sign in to track this

What mastery looks like

  • 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)

Check your understanding

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?
