# Stage 1, mathematics, Year B – Unit 36

This two-week unit develops student knowledge and skills in understanding the many different situations where addition, subtraction, multiplication and division can be used.

Students are provided opportunities to:

• investigate the 4 operations through problem solving
• explore inverse operations
• engage in meaningful activities using repeated halving and doubling.
