Number > Adding & Subtracting

Australian Curriculum Version 9 Says:

Represent practical situations involving addition, subtraction and quantification with physical and virtual materials and use counting or subitising strategies.

What this means

Given addition and subtraction story problems (orally) students use materials to act out the situation.

  • For example, “I have three toy dinosaurs and my friend gave me two more dinosaurs. How many dinosaurs do I have now?”
  • Quantification; the act of counting and measuring, expressing something as an amount or number.

Tip

  • The addition and subtraction situations would involve numbers up to ten using subitising or counting to work out the answer.
