Mathematical modelling to solve practical problems involving additive and multiplicative...

Quick preparation

• use mathematical modelling to solve practical problems involving additive and multiplicative situations including financial contexts; formulate…
• modelling practical additive situations, choosing whether to use an addition, subtraction or both when representing the problem as a number sentence,…
• modelling additive problems using a bar model to represent the problem; for example, “I had 75 tomatoes and then picked some more, now I have 138.…
