Maths

This lesson looks at the links between multiplying by 4 and by 8. We have already looked at multiplying by 4 in the previous two lessons and therefore we already know the numbers that are seen in the 4 times table.

To begin this lesson, we will look at the In Focus task.
Can you think of different ways to work out how many doughnuts there are altogether?

 Mrs Metcalfe’s friend said that the 4 and 8 times tables are connected. What does her friend mean?
Can you use the pictures to explain?

Can you see that for every 2 fours we make an 8.
So 2 groups of 4 (2 × 4) is the same as 1 group of 8 (1 × 8); 4 groups of 4 (4 × 4) is the same as 2 groups of 8 (2 × 8). Can you show other examples from the 4 and 8 times tables?

Now write the 4 times table and the 8 times table, side by side, in your blended learning book or in your maths jotter.

 Can you see any patterns?

 Do you see that the 8 times table is double the 4 times table? 
So 2 × 4 = 8 and 2 × 8 = 8 + 8 = 16. 

Can you draw a picture, using dots, that represents 6 × 8? 

Well done if you have drawn 6 rows of 8 dots. What is the answer? 
We are going to start using the word 'product' which means 'to multiply'.
So we can say that the product of 6 and 8 is 48.

 

Use your knowledge of the times tables and the strategies you have learned to complete the guided practice.
