Pocket money: Mathematical modelling

In this second of three lessons, students use mathematical modelling to solve problems that involve financial decisions.

They will be guided to use the 4-step problem solving model to support them to unpack the problem, generate a plan to help solve it, and check their ability to work mathematically.

Students will explore different ways to estimate and form possible solutions to the total earnings over a period of time. The lesson allows students to be creative in the way they infer the stated problem and select strategies to find possible solutions.

They will communicate their thinking and justify their approach to the problem and their solutions.

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

AC9M4A02
Recall and demonstrate proficiency with multiplication facts up to 10 x 10 and related division facts; extend and apply facts to develop efficient mental strategies for computation with larger numbers without a calculator

AC9M4N08
Use mathematical modelling to solve practical problems involving additive and multiplicative situations including financial contexts; formulate the problems using number sentences and choose efficient calculation strategies, using digital tools where appropriate; interpret and communicate solutions in terms of the situation
