Number > Operations +-×÷

Australian Curriculum Version 9 Says:

Develop efficient strategies and use appropriate digital tools for solving problems involving addition and subtraction, and multiplication and division where there is no remainder.

What this means

Calculating with all four operations (+ -, ×, ÷). Note: no remainders.

  • Students will need to link their place value understanding with basic fact knowledge to perform calculations.
  • Efficient strategies; strategies that don’t tax working memory.
  • Diagrams (such as the bar model) and materials can help students formulate number sentences which they solve.
  • Year 4 is the final year that focuses purely on addition and subtraction of whole numbers. In Year 5 addition and subtraction are applied to solving word problems. In Year 6 students add and subtract decimals. Whole number addition and subtraction will need to be consolidated in this year.

Tips

  • All the examples given in the elaborations use single and two-digit numbers.
  • Be careful linking key words to a single operation.
