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.

Outcomes

3.OA.C.7

Fluently multiply and divide within 100. By the end of grade 3, know from memory all multiplication products through 10 x 10 and division quotients when both the quotient and divisor are less than or equal to 10.

PRACTICE: Multiply by 5 and 10
