Worksheet Overview

QUESTION 1 of 10

So you've decided to spend some time using known times table facts in order to solve multiplication and division problems.

 

What are the known facts?

In this activity, the known facts you will use are times tables with related division facts.

By the end of Year 4, you are expected to know all of the multiplication and related division facts for all of the times tables up to 12x.

 

Why do we use known facts?

Known facts are a great way to work out related facts and to help you solve larger, more complex calculations.

 

Example 1:

20 x 6 = ?

We know 2 x 6 = 12

So, 20 x 6 = 120

The ten from 12 becomes 100 and the 2 becomes 20.

 

Example 2:

In class 6E, there are 20 pupils and each earns 14 housepoints in one week.

How many housepoints do they earn in total?

 

We use a known fact first: 

14 x 2 = 28

So, 14 x 20 = 280

The 20 from the 28 becomes 200 and the 8 becomes 80.

So, 14 x 20 = 280 housepoints.

 

Now it's over to you now to have a go at some practise questions, good luck!

Use your knowledge of known facts to solve:

 

360 ÷ 6 = ?

Use your knowledge of known facts to solve:

 

630 ÷ 7 = ?

Can you correctly match the statements with their correct answers?

Column A

Column B

540 ÷ 9 =
90
450 ÷ 5 =
60
320 ÷ 8 =
40
240 ÷ 4 =
60

Can you correctly match the statements with their correct answers?

Column A

Column B

4 x 40 =
560
70 x 8 =

In class 6E, there are 20 pupils and each earns 14 housepoints in one week.

How many housepoints do they earn in total?

 

We use a known fact first: 

14 x 2 = 28

So, 14 x 20 = 280

The 20 from the 28 becomes 200 and the 8 becomes 80.

So, 14 x 20 = 280 housepoints.

 

In the Year 5 class, there are 21 children who all gain 14 housepoints in a week.

Use the information given to find out how many housepoints in total class 5E earned.

In class 6E, there are 20 pupils and each earns 14 housepoints in one week.

How many housepoints do they earn in total?

 

We use a known fact first: 

14 x 2 = 28

So, 14 x 20 = 280

The 20 from the 28 becomes 200 and the 8 becomes 80.

So, 14 x 20 = 280 housepoints.

 

What if there were only 19 children in class 6E- how many housepoints would be earned in total?

14 x 11 = 154

 

Using this number fact, solve the calculations below:

  • Question 1

Use your knowledge of known facts to solve:

 

360 ÷ 6 = ?

CORRECT ANSWER
60
EDDIE SAYS
How did you get on with this first question? Remember to use your times' table knowledge with related division facts to help you. We know that 36 ÷ 6 = 6 So, 360 ÷ 6 = 60
  • Question 2

Use your knowledge of known facts to solve:

 

630 ÷ 7 = ?

CORRECT ANSWER
90
EDDIE SAYS
Great job if you wrote 90. We know that 63 ÷ 7 = 9 630 ÷ 7 = 90 You've made a good start- let's push on.
  • Question 3

Can you correctly match the statements with their correct answers?

CORRECT ANSWER

Column A

Column B

540 ÷ 9 =
60
450 ÷ 5 =
90
320 ÷ 8 =
40
240 ÷ 4 =
60
EDDIE SAYS
Don't worry if you found this challenging. The best way to improve at this type of question is to make sure you know all of your times' tables. You can then use your place value and times table knowledge to work out the correct answer.
  • Question 4

Can you correctly match the statements with their correct answers?

CORRECT ANSWER

Column A

Column B

4 x 40 =
160
70 x 8 =
560
80 x 11 =
880
9 x 60 =
540
EDDIE SAYS
You're getting the hang of this! Again, you should've been using your prior times' table knowledge in order to answer these multiplication questions.
  • Question 5

How many 6's are there in 120?

 

How do you know? Prove your answer with numbers!

CORRECT ANSWER
EDDIE SAYS
1st mark available for the correct answer of 20. 2nd mark available for working out, for example: 12 ÷ 6 = 2 So, 120 ÷ 6 = 20. The pupil will need to use knowledge of times tables and place value to demonstrate their understanding of this question.
  • Question 6

What are the answers to these?

 

CORRECT ANSWER
EDDIE SAYS
To crack this one, we were able to use our knowledge of the 6 times table to divide larger numbers. For example: If we know 42 ÷ 6 = 7 then, 420 ÷ 6 = 70. This is incredible progress, you are now more than halfway through this activity.
  • Question 7

What are the answers to these?

 

CORRECT ANSWER
EDDIE SAYS
Great focus - there was a lot of information to think about here in this question. The more you practise using known facts, the easier it will be to instantly recall them.
  • Question 8

In class 6E, there are 20 pupils and each earns 14 housepoints in one week.

How many housepoints do they earn in total?

 

We use a known fact first: 

14 x 2 = 28

So, 14 x 20 = 280

The 20 from the 28 becomes 200 and the 8 becomes 80.

So, 14 x 20 = 280 housepoints.

 

In the Year 5 class, there are 21 children who all gain 14 housepoints in a week.

Use the information given to find out how many housepoints in total class 5E earned.

CORRECT ANSWER
EDDIE SAYS
Phew, that was a toughie! Hopefully, you used the information given to help you. 14 x 21 = (14 x 20) + (14 x 1) = 280 + 14 = 294 housepoints.
  • Question 9

In class 6E, there are 20 pupils and each earns 14 housepoints in one week.

How many housepoints do they earn in total?

 

We use a known fact first: 

14 x 2 = 28

So, 14 x 20 = 280

The 20 from the 28 becomes 200 and the 8 becomes 80.

So, 14 x 20 = 280 housepoints.

 

What if there were only 19 children in class 6E- how many housepoints would be earned in total?

CORRECT ANSWER
EDDIE SAYS
How did you get on? You can use the information given: 14 x 19 = (14 x 20) – (14 x 1) = 280 - 14 = 266 housepoints. One more question to go- you've got this!
  • Question 10

14 x 11 = 154

 

Using this number fact, solve the calculations below:

CORRECT ANSWER
EDDIE SAYS
Did you spot that all of the numbers you would need were in the number sentence 14 x 11 = 154? All you had to do was rearrange the numbers correctly. Great work maths-whiz, that’s another activity completed!
