In this lesson, we will use mental strategies such as partitioning and adjustment to multiples of ten to add a range of two digit numbers together. .

In this lesson, we will use different mental strategies to calculate subtraction such as partitioning, counting on and using known facts.

In this lesson, we will be implementing a variety of addition and subtraction strategies to real world scenarios.

In this lesson, we will explore the laws of multiplication, and use known facts and the laws of commutativity and associativity to perform efficient multiplication.

In this lesson, we will use doubling and halving skills to efficiently calculate multiplication and division involving a factor of 2.

In this lesson, we will extend our knowledge of place value into the thousands place, and look at unit conversions that require knowledge of four digit numbers.

In this lesson, we will use place value knowledge to count in hundreds, investigate the number 1000 and compare the value of each digit in different four digit numbers.

In this lesson, we will use place value knowledge to compare four digit numbers and place them in ascending and descending order of size.

In this lesson, we will learn how to add and subtract 1000 using our understanding of place value. We will also investigate a range of visual representations of subtraciton.

In this lesson, we will learn to round four digit numbers to the nearest multiple of 1000 using different visual representations such as number lines and bead strings.
