10) Addition

Bonds of 5: Building a Wall

10.1 Addition Building A Wall


Develop the concept of:

  • The whole number 5 being equal to two parts joined together (two-part bond of five).
  • The commutative property of addition.

Develop fluency using bonds of 5 in addition equations, expressed verbally.


  • addition as “add”
  • equals
  • part-part-whole
  • The Commutative Property of Addition: swapping the order of the parts does not alter the size of the whole.


A little easier

Build a wall

Build a wall of 5 that requires students to use the commutative property of addition to identify two-part bonds. Use one of each block from 1 to 5. Keep this on the game board whilst playing.

10 Desk Visual

These part-part-whole diagrams  can be stuck to the top of student’s desk, as a desk visual, until students are fluent recalling these facts. Students with memory or processing difficulties can benefit from having visuals as permanent prompts.
