Use flexible strategies to solve addition and subtraction problems
Use non-count-by-one strategies such as using doubles for near doubles and combining numbers that add to ten
Represent addition and subtraction using structured materials such as a bead string or similar model
Select and apply strategies using number bonds to solve addition and subtraction problems with one- and two-digit numbers by partitioning numbers using quantity value and bridging to 10 (Reasons about relations)
Represent equality
Use the equals sign to record equivalent number sentences involving addition, and to mean 'is the same as', rather than as an indication to perform an operation
Model the commutative property for addition and apply it to aid the recall of addition facts
Recall related addition and subtraction facts for numbers to at least 10
