Welcome to KS2 Maths Parent Workshop Let’s start doing some Maths…. Add these numbers up: 0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 What strategies did you use?

KS2 – Years 3, 4, 5 and 6 Addition Subtraction Division Multiplication

Understanding number Number bonds are the window to success in KS2 and it is vital that your child knows these securely as they enter this phase. By the end of Year 4, your child is expected to know all their times tables up to 12 x 12. To ensure this, we practise the tables daily and explore connections between the tables, e.g. to find 6 x 8, we know 5 x 8 is 40, so 6 x 8 is one more 8, so is 48.

An App to download to help with times table learning: 100 Squares Calc. My Maths also has a good bingo activity in the Games section.

Models for multiplication Fingers But these images aren’t commutative “3” “6” “9” “12” Bead Bar 3  4 4  3 Number Line 3 6 9 12

5 6 7 8 56  7 The array is an image for division too Either: Try some for yourself: Choose a number of counters Make an array Describe it to each other using ×’n and ÷’n language Record it in an equation using × and ÷ symbols 56  7 Either: How many 7s can I see? (grouping) Or: If I put these into 7 groups how many in each group? (sharing) The array is an image for division too 5 6 7 8

An image for 56  7 5 6 7 8 How many 7s can I see?

5 6 7 8 How many 7s can I see?

8 How many 7s can I see? 7 5 6

8 How many 7s can I see? 7 5 6

120  3 The power of the place value: counters for larger numbers Is this sharing or grouping? 40 120 3 26

1200  3 Similarly for 100s 400 1200 3 27
