Australian Curriculum Version 9 Says:

Use mathematical modelling to solve practical problems involving additive and multiplicative situations, including money transactions; represent situations and choose calculation strategies; interpret and communicate solutions in terms of the situation.

What this means

Students need to decide whether they should add or subtract (additive situations) or multiply or divide (multiplicative situations) to solve a problem.

  • Drawing diagrams, such as part-part-whole diagrams will help students understand problems (additive).
  • There are several diagrams and methods that will help students understand which type of problem (additive, multiplicative) they are dealing with.

Tips

  • Note the elaborations mention remainders in the context of modelling and solving practical problems. That is, acting out the problem. This does not refer to calculating with a remainder.
