  1. Fun with fives I am learning to work out my times six, seven, and eight tables from my times five tables.

  2. Fly cards look like this. They can have up to 5 objects on one side and up to 5 objects on the reverse side. This card has 3 objects on the reverse. This card represents 8. It has 5 objects on the front and 3 on the back. 5 3 Front Back

  3. Let’s imagine we had 6 fly flips with 7 circles on them. There are 5 circles on the front and 2 circles on the back. How many circles are there in total? 6 X 7 = ? First let’s work out how many there are on the front. 6 X 5 = 30 Now let’s turn them over and work out how many there are on the back. 6 X 2 = 12 Now add the two amounts together 6 X 5 = 30 and 6 X 2 = 12. 30 + 12 = 42 That means 6 X 7 = 42 6 X 7 is the same as (6 X 5) + (6 X 2) 2 2 2 2 2 2 5 5 5 5 5 5

  4. Let’s imagine we had 4 fly flips with 8 circles on them. There are 5 circles on the front and 3 circles on the back. How many circles are there in total? 4 X 8 = ? First let’s work out how many there are on the front. 4 X 5 = 20 Now let’s turn them over and work out how many there are on the back. 4 X 3 = 12 Now add the two amounts together 4 X 5 = 20 and 4 X 3 = 12. 20 + 12 = 32 That means 4 X 8 = 32 4 X 8 is the same as (4 X 5) + (4 X 3) 5 5 5 5 5 5 5 5

  5. The questions to the left can be made easier by imagining them on fly flips. Which questions go together? 1) 3 X 7 = ? 2) 4 X 8 = ? 3) 6 X 7 = ? 4) 8 X 6 = ? 5) 4 X 6 = ? (6 X 5) + (6 X 2) = 42 (4 X 5) + (4 X 1) = 24 (3 X 5) + (3 X 2) = 21 (4 X 5) + (4 X 3) = 32 (8 X 5) + (8 X 1) = 48

  6. Now try these questions on your own. Click again when you have worked out all your answers. 1) 3 X 8 = ? 2) 6 X 6 = ? 3) 3 X 6 = ? 4) 4 X 7 = ? 5) 6 X 8 = ? 24, (3 X 5) + (3 X 3) 36, (6 X 5) + (6 X 1) 18, (3 X 5) + (3 X 1 ) 28, (4 X 5) + (4 X 2) 48, (6 X 5) + (6 X 3) Need some more practise?
