What to Focus On

  • A number can describe an arrangement, not only a count.
  • The number said by a child depends on taller children in front.
  • The first person in line always says 0.
  • Parity means evenness or oddness.
  • Even numbers can be arranged in pairs without leftovers.
  • Odd numbers leave one extra after pairing.
  • An odd number of odd addends gives an odd total.
  • 5 odd numbers can never add to 30.
  • Consecutive numbers always add to an odd number.

Common Mistakes to Avoid

Any 5 odd number cards can sometimes add up to 30.

Two consecutive ages can add up to an even number like 112.

Odd + odd can give an odd number if the odd numbers are large enough.

Memory Tips
