Elaboration (1) ACMNA029

using counting on to identify the missing element in an additive problem

Elaboration ACMNA030

becoming fluent with a range of mental strategies for addition and subtraction problems, such as commutativity for addition, building to 10, doubles, 10 facts and adding 10

recognising that sets of objects can be partitioned in different ways to demonstrate fractions

Elaboration (1) ACMNA033

relating the number of parts to the size of a fraction

Elaboration ACMNA034
