  6. Possible response: Disagree. Ann must have counted her cubes wrong. I skip counted by twos on the number line. I landed on 22, so 23 is odd.

Q. Odd or Even

Determine if each number is odd or even. Tell your neighbor how you decided.

  1.  98         ____________________
  2.  23         ____________________
  3.  37         ____________________
  4.  135         ___________________
  5.  74         ____________________
  6.  Ann said, “I can tell 23 is even because I used connecting cubes and made two towers the same size.” Do you agree with Ann?
