use mathematical modelling to solve practical problems involving additive situations including simple money transactions; represent the situations with diagrams, physical and virtual materials, and use calculation strategies to solve the problem

Elaborations

  • AC9M1N05_E1modelling problems involving addition and subtraction presented in stories, using a Think Board to represent the problem, solving the problem using physical materials and explaining the connections between any materials used, the Think Board diagram and the numbers within the story
  • AC9M1N05_E2modelling simple money problems involving addition and subtraction using whole dollar amounts; for example, setting up a shop and role-playing practical problems of buying and selling of goods, using addition and subtraction with play money and prices in whole dollar amounts; solving the problem “I had $14 and was given $15 for my birthday” using addition to answer the problem
