Bonds of 10: Building a Wall

29.1 Addition Building A Wall

  • The whole number 10 being equal to two parts joined together (two-part bond of five).
  • The commutative property of addition.

Develop fluency using bonds of 10 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.
