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!

6 Times Table and Division Facts Diving Use doubling and halving to help calculate the missing multiples from the 3× and 6× tables. 3× 6× 24 4 lots of 3 double 66 11 groups of 3 double 24 halve 8 times 6 3 halve 1 multiplied by 6

6 Times Table and Division Facts Diving Fill in the missing boxes in each calculation. 24 10 4 600 × = 2400 4 × 6 = × 6 = 60 60 60 4 × = 240 10 × 6 = × 10 = 6000 600 Connect each fact to another related fact in a different column.

6 Times Table and Division Facts Diving Colour the multiples of 6 and associated multiples from the 60× or 600× tables to reveal a number. What is the number? 6 66 12 18 15 21 5400 42 240 72 9 180 60 7200 600

6 Times Table and Division Facts Deeper Explain which one is the odd one out. 2 × 6 = 5 × 6 = 12 12 30 30 12 × 6 = 72 72 6 × 6 = 36 36 Did you come up with 5 × 6 = 30 is the odd one out because another way of explaining it is the only answer that is in the which is the odd one out? 10× table as well as the 6× table.

6 Times Table and Division Facts Deeper Read the statement below. Is it true or false? Explain your answer. The greatest number in the 6 times table is 72 because 12 × 6 = 72. 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.

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

6 Times Table and Division Facts 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 If you are confident with your times tables, have a go at completing the challenge. 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?

The 8 Times Table Diving Complete these statements. 8 1 chest contains 8 gold coins. 2 chests contain gold coins. 16 chests contain 40 gold coins. 5 80 10 chests contain gold coins. Which statements match this image? 8 ÷ 16 = 2 2 x 8 = 16 16 ÷ 8 = 2

The 8 Times Table Deeper Which models represent facts from the eight times table? Explain your reasons. 32 This model is correct. It shows 4 groups of 8 equalling 32. 8 8 8 8 This model is not correct. 2 × 8 This model shows two parts of 2 × 8, which 5 × 8 each equal 16. The whole shows 5 × 8. 2 × 8 2 × 8 and 2 × 8 would only equal 4 × 8. This model is correct. It shows 6 × 8 = 48 or 48 ÷ 8 = 6.

The 8 Times Table Deepest Pirate Priti has fewer than 45 parrots to arrange into cages on the pirate ship. If she sorts them in groups of eight, she has none left over. If she sorts them into groups of three, she has two left over. How many parrots could she have? Find all the possibilities. Number Left If Divided Possible Multiples of 8 into Groups of 3 8 2 8 parrots 16 1 24 0 32 2 32 parrots 40 1
