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
