# Times tables: x/÷ facts

Maths Year 4
This unit is part of Year 4 Flexible Maths Blocks Multiplication and Division and Year 4 Maths Planning Multiplication and Division (A)

### Planning and Activities

Day 1 Teaching
Count in 9s along a counting stick. Rehearse division facts, e.g. How many 9s are in 27? How many 9s are in 45? Demonstrate the ‘finger trick’ of showing 9 times tables facts. Point out that the digits of each multiple of 9 add to 9. This is the ‘digital root’ or ‘digit sum’ and is an important ‘test for divisibility’.
Group Activities
-- Explore all multiplication and division facts for the 9 times table.

Day 2 Teaching
Count in 7s along a counting stick. Rehearse division facts, e.g. How many 7s are in 21? How many 7s are in 42? Launch ITP ‘Number grid’. Use the toggle to highlight multiples of 7. Describe the pattern to partner. Discuss ways to remember facts from the 7 times table.
Group Activities
Use the in-depth problem-solving investigation ‘Table digital roots’ as today’s group activity.
Or, use these activities:
-- Explore all multiplication and division facts for the 7 times table.

Day 3 Teaching
Children write out the first seven multiples of the 11 times table, noticing the pattern. The 11 times table has a memorable pattern until we reach 10 × 11. How can we use 110 as a starting point to find 11 x 11 and 12 x 11? Write out the first few facts for the 12 times table. How will we find 8 × 12? Use partitioning to find 8 x 12.
Group Activities
-- Explore multiplication facts for the 11 and 12 times tables.

### You Will Need

Multiplication and division facts (pre-requisite skills)

Day 3
9 and 90 times tables (pre-requisite skills)

### Worksheets

Day 1
Solve multiplications and divisions with the 9 times table.

Day 2
Use the multiplication grid to solve calculations, applying the 7 times table.

Day 3
Solve multiplications and divisions with the 11 and 12 times tables.

### Mastery: Reasoning and Problem-Solving

• Which of these numbers are multiples of 9?
28, 108, 126, 49, 153, 891 How do you know?
• Which of these numbers are multiples of 7?
84, 79, 32, 63, 56, 140, 133
How do you know?
• Complete this grid in under 1 minute.
 x 7 9 12 5 7 8
• Write a word problem to help practise the 11 times table. Your word problem must have one of these answers:
88p, 132cm, £121, 154 minutes.

In-depth Investigation: Table Digital Roots
Children find the digital roots of multiples of 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12. They identify patterns and relate these to what they know of numbers.
