# Stage 3, mathematics, Year B – Unit 27

This 2-week unit develops the big idea that multiplicative thinking involves flexible use of multiplication and division concepts, strategies and representations.

Students are provided opportunities to:

- identify, describe and apply multiplicative patterns
- learn and apply a range of concepts, strategies and representations for multiplication and division
- share their reasoning for applying multiplicative strategies in particular situations.

**Represents numbers A – MAO-WM-01, MA3-RN-01**

Whole numbers: Apply place value to partition, regroup and rename numbers to 1 billion

**Additive relations A – MAO-WM-01, MA3-AR-01**

Apply efficient mental and written strategies to solve addition and subtraction problems

**Multiplicative relations A – MAO-WM-01, MA3-MR-01**

- Use partitioning and place value to multiply 2-, 3- and 4-digit numbers by one-digit numbers
- Represent and solve division problems with whole number remainders
- Use estimation and rounding to check the reasonableness of answers to calculations

**Multiplicative relations B – MAO-WM-01, MA3-MR-01, MA3-MR-02**

- Select and apply strategies to solve problems involving multiplication and division with whole numbers
- Multiply and divide decimals by powers of 10
- Use equivalent number sentences involving multiplication and division to find unknown quantities
