6 and 8 Times Table and Division Facts

Diving into Mastery Guidance for Educators

Diving Deeper Deepest

Aim

• This week we are really focusing on securing the 6 and 8

multiplication tables. It is really important to be able to recall these facts to help you with mental calculations and to help you with things like long multiplication.

• We would like everyone to practise their TTRockstars each day this

week, but if you have any other ways to help you remember your tables, then please use these methods too.

• If you are already really secure with your 6 and 8 multiplication

facts (you can recall any calculation from 1x6 to 12x6 and 1x8 to 12x8 in about 2 seconds when asked in a random order) then there are a two investigations for you to complete.

• Have fun!

Diving 6 Times Table and Division Facts

Use doubling and halving to help calculate the missing multiples from the 3× and 6× tables. 3× 6× double double halve halve

Fill in the missing boxes in each calculation.

4 × 6 = 10 × 6 = × 6 = 60 600 × = 2400

Connect each fact to another related fact in a different column.

4 × = 240

Colour the multiples of 6 and associated multiples from the 60×

• r 600× tables to reveal a number. What is the number?

6 Times Table and Division Facts Deeper

Explain which one is the odd one out.

2 × 6 = 5 × 6 = 12 × 6 = 6 × 6 = 12 12 30 30 72 72 36 36

5 × 6 = 30 is the odd one out because it is the only answer that is in the 10× table as well as the 6× table. Did you come up with another way of explaining which is the odd one out?

6 Times Table and Division Facts Deeper

Read the statement below. Is it true or false? Explain your answer. This is false because, if we wanted, we could continue to 13 × 6 and beyond: 13 × 6 = 78, 14 × 6 = 84, 15 × 6 = 90. Times table are endless; we just choose to stop at 12 × because these are the most used facts. The greatest number in the 6 times table is 72 because 12 × 6 = 72.

6 Times Table and Division Facts Deepest Use the numbers in the target board to create the target number 6 from division and multiplication calculations that contain 3× and 6× table facts and related facts. The numbers on the board may be used more than once per calculation. Find as many solutions as you can.

Some possible answers: 3 × 2 = 6 2 × 3 = 6 12 ÷ 2 = 6 24 ÷ 2 ÷ 2 = 6

Dive in by completing your own activity! If you are confident with your times tables, have a go at completing the challenge on the next slide.

6 Times Table and Division Facts

Challenge Activity All the 6s Using four 6s and any operations you need, can you make the number 74? Can you make the number 5? Can you make the number 12? How many different was can you make 12? Can you make all the numbers from 0-20? If you are confident with your times tables, have a go at completing the challenge.

This model is correct. It shows 6 × 8 = 48 or 48 ÷ 8 = 6. This model is not correct. This model shows two parts of 2 × 8, which each equal 16. The whole shows 5 × 8. 2 × 8 and 2 × 8 would only equal 4 × 8. This model is correct. It shows 4 groups of 8 equalling 32.
