add and subtract numbers within 20, using physical and virtual materials, part-part-whole knowledge to 10 and a variety of calculation strategies

• using drawings, physical and virtual materials, and number combinations within 10 to add and subtract collections to 20
• adding and subtracting numbers within 20, using a variety of representations and strategies, such as counting on, counting back, partitioning and partpart-whole knowledge of numbers to 10; for example, using partitioning and combining 7 + 5 = 7 + 3 + 2 = 10 + 2 = 12
• developing and using strategies for one-digit addition and subtraction based on part-part-whole relationships for each of the numbers to 10 and subitising with physical and virtual materials; for example, 8 and 6 is the same as 8 and 2 and 4
• representing story problems involving addition and subtraction of numbers within 20 using a Think Board; recognising and using + and − symbols and the equal sign (=) to represent the operations of addition and subtraction; and showing and explaining the connections between any materials used using the language of plus and minus, and the numbers within the story problem
• creating and performing addition and subtraction stories told through Aboriginal and/or Torres Strait Islander dances
