Recalling the 3 times table

In this lesson, we will introduce the 3 times table and look at the key vocabulary 'products' and 'multiples'. We will use visual representations to aid our understanding including number lines, and real life objects.

Recalling the 4 times table

In this lesson, we will introduce the 4 times table through skip-counting, and represent multiples of 4 in a number of visual ways. We will compare the terms multiple and product.

Using arrays to represent the 3 and 4 times tables

In this lesson, we will create and use arrays to visually aid multiplication, and accurately answer questions. We will study the difference between visualising columns and rows, and the effect on how the calcuation is written.

Understanding multiplication can be completed in any order

In this lesson, we will introduce the term 'communtativity', and study the properties and laws of multiplication. We will use arrays to prove that multiplication is commutative.

Understanding that multiplication and division are inverse operations

In this lesson, we will explore the concept of inverse operations with regards to multiplication and division. As a result, we will use our times tables knowledge to help us answer division questions.

Using the inverse operation to find missing numbers

In this lesson, we will use our knowledge of multiplication and division 'fact families' in order to find the missing number in a range of questions. We will use arrays to represent the relationship between inverse operations, and explore how fact families around multiplication and division help us discover new facts about multiplication and division.

Using factors and products to solve division problems

In this lesson, we will be using and applying known facts around fact families, multiples and factors to solve problems. We will, for example, look at how factors of a number help us determine multiples of near numbers.
