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.
