Bonds of 10: Building a Wall
Develop the concept of:
- 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”
- The Commutative Property of Addition: swapping the order of the parts does not alter the size of the whole.
