Addition and subtraction

In this lesson, we will derive addition and subtraction facts by using part whole models to show how related facts can be derived from scaling up by 10, 100 or 1000.

In this lesson, we will derive addition and subtraction facts by using given calculations, consider how the whole or parts have changed and the impact this has on the new calculation.

In this lesson, we will look at addition equations and decide the best and most efficient strategy we could use to solve them.

In this lesson, we will look at subtraction equations and decide the best and most efficient strategy we could use to solve them.

In this lesson, we will apply and consolidate our knowledge of deriving related number facts and most efficient strategies for calculating addition and subtraction equations. We will recap our key learning and apply that learning to answer different questions.

In this lesson, we will use the column method to add two four digit numbers where regrouping is required in one column.

In this lesson, we will use the column method to add two four digit numbers where regrouping is required in multiple columns.

In this lesson, we will use the column method to subtract two four digit numbers where regrouping is required in one column.

In this lesson, we will use the column method to subtract two four digit numbers where regrouping is required in multiple columns.

In this lesson, we will explore how to calculate from a multiple of 1000.

In this lesson, we will consolidate our knowledge of the column method for both addition and subtraction by recapping the method, completing examples and applying our learning.

In this lesson, we will use bar models to represent addition and subtraction in one-step word problems.

In this lesson, we will use comparison bar models to represent addition and subtraction in one-step word problems.

In this lesson, we will use bar models to represent two-step addition and subtraction word problems.

In this lesson, we will recap our knowledge of how to use bar models to represent word problems which require addition or subtraction.
