Bonds of 5: Tic-Tac-Toe

8.1 Fluency Tic Tac Toe


Develop fluency identifying the missing part in two-part bonds of 5.

Develop the concept of using part-part-whole representation.


  • addition as “and”
  • equals as “is”, “is equal to”
  • horizontally, vertically, diagonally


A little easier

Place blocks on the game board

This activity is more difficult than the previous activities in the Bonds of 5 Chapter because it is diagrammatic representation. Support students experiencing difficulty by placing blocks on the Part-Part-Whole frame.

For example, spinning 3.

When using the Part-Part-Whole frame it is important to be clear that the whole on the top row is worth the same as the parts joined underneath. This is NOT a diagram of 5+5=10

Model spinning 5.

Model spinning zero.
