This activity is about multiplying by 6, 7, 9, 11 and 12.
In other activities, we have learnt some tips and tricks for recalling our times tables.
In this activity, we will be practising mixed facts from the 6, 7, 9, 11 and 12 times tables.
Here are some tips and tricks:
1. Count up or down in multiples from a known fact.
2. Partition the multiplication. For 12s, we can multiply by 10 and 2, then add the totals.
3. Use an inverse calculation to help. If you don't know 7 x 3, maybe you know 3 x 7.
Example
A cookie has 9 chocolate chips.
How many chocolate chips do 12 cookies have?
What is 9 times 12?
Answer
Step 1: 9 x 10 = 90
Step 2: 9 x 2 = 18
Step 3: 90 +18 = 108
9 × 12 = 108
Now try the questions for yourself.
