Step-by-step Maths Level 4 Times tables 6, 8 and 9: check-up and practice test questions

Method. Count in 8s to find 8 groups of 5. The order of the two numbers does not matter.

1. Count in 8s, 5 times. Each count adds one more group of 8.
   8, 16, 24, 32, 40
2. The last number we said is the answer. We counted in equal groups.
   8 × 5 = 40
3. Write the answer. The order of the numbers does not change the answer.
   40

Check. Check: 5 × 8 is also 40.

Watch out. Say the 8 times table in order until you reach the fact you need.

Method. Count in 8s to find 8 groups of 12. The order of the two numbers does not matter.

2. The last number we said is the answer. We counted in equal groups.
   8 × 12 = 96
3. Write the answer. The order of the numbers does not change the answer.
   96

Check. Check: 12 × 8 is also 96.

Watch out. Say the 8 times table in order until you reach the fact you need.

Method. Use the 3 or 4 facts. Count in steps of the number to find the missing number.

1. Think of the times table of 8. The missing number is the number of groups of this size.
   8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96

   3 - 1 = 2
2. Find the ones digit. The two digits must add to 9.
   9 - 2 = 7
3. Write the answer. Put the tens digit and the ones digit together.
   27
