PRACTICE: Multiply by 5 and 10

Lesson

Practice

Now that we have learned about the connection between the $10$10 times tables and the $5$5 times tables, let's practice multiplying by fives and multiplying by tens together.

 

Apply

Question 1

$10\times7$10×7

Question 2

$10\times4$10×4

Question 3

$8\times5$8×5

 

Remember!

To find the answers for our $5$5 times tables we can use a halving strategy because half of $10$10 groups is $5$5 groups. 

Alternatively, you can also reverse this strategy and double the answers to $5$5 times tables to work out the answers to the $10$10 times tables.
