In this 2-week unit students are provided opportunities to:
- represent and partition numbers using place value
- select strategies to efficiently solve problems in addition, subtraction, multiplication and division
- create a simple map and mark locations using the structure of a grid.
Representing numbers using place value A – MAO-WM-01, MA2-RN-01
Whole numbers: Apply place value to partition and regroup numbers up to 4 digits
Representing numbers using place value B – MAO-WM-01, MA2-RN-01
Whole numbers: Recognise and represent numbers that are 10, 100 or 1000 times as large
Additive relations A – MAO-WM-01, MA2-AR-01
- Use the principle of equality
- Recognise and explain the connection between addition and subtraction
- Select strategies flexibly to solve addition and subtraction problems of up to 3 digits
- Represent money values in multiple ways
Additive relations B – MAO-WM-01, MA2-AR-01
Partition, rearrange and regroup numbers to at least 1000 to solve additive problems
Mulitplicative relations A – MAO-WM-01, MA2-MR-01, MA2-MR-02
Recall multiplication facts of 2 and 4, 5 and 10 and related division facts
