Multiplication (x) Year Just know it! EYFS They solve problems, including doubling, halving and sharing. 1 2 3 4 Count in 2s 2 x table Review 2x, 5x and 10x tables 4x, 8 x tables 10 times bigger Count in 10s 10 a table 4x table 3x, 6x and 12x tables Doubles up to 10 Doubles up to 20 and multiples of 5 Double 2 digit numbers Count in 5s 5 x table 8 x table Double larger numbers and decimals 3x, 9x tables Double multiples of 10 Count in 3s 3 x table 11x, 7x tables Count in 2s, 5s and 10s Written methods Developing conceptual understanding 2 frogs on each lily pad. 2x, 5x and 10x tables 6 x tables or review others 6x, 12x tables Calculate mathematical statements for multiplication and division within the multiplication tables and write them using the multiplication (x) and division (÷) and equals (=) signs. Examples? Write and calculate mathematical statements for ÷ and using the x tables they know progressing to formal written methods. Examples? Multiply 2-digit and 3digit numbers by a 1digit number using formal written layout 5 frogs on each lily pad 5 x 3 = 15 (showing multiplication as groups of) 13 x 4 = (10 x 4) + (3 X 4) =52. i)52 x 3 = 52 3x 156 5 x 2 = 2 x 5 (showing multiplication as an array) Build tables on counting stick Link to repeated addition ii) 243 x6 = 5 4x, 8x tables 100, 1000 times bigger 3x, 6x, 12x tables 10, 100, 1000 times smaller Double larger numbers and decimals 3x, 9x tables 6 Multiplication facts up to 12 x 12 Partition to multiply mentally Double larger numbers and decimals Multiplication facts up to 12 x 12 11x, 7x tables Partition to multiple mentally 6x, 12x tables Multiply numbers up to 4 digits by a 1- or 2- digit number using a formal written method, including long multiplication for 2- digit numbers. Multiply multi-digit numbers up to 4 digits by a 2- digit whole number using the formal written method of long multiplication. Multiplication (x) With jottings Or mental calculations Examples Solve one step problems involving multiplication and division, by calculating the answer using concrete objects, pictorial representations and arrays with the support of the teacher. Show that multiplication of 2 numbers can be done in any order (commutative) and division of one number by another cannot. Solve problems involving multiplication and division, using materials, arrays, repeated addition, mental methods, and multiplication and division facts, including problems in contexts. Write and calculate mathematical statements for multiplication and division using the multiplication tables that they know, including for TO x O, using mental methods. Use place value, known and derived facts to multiply and divide mentally, including: multiplying by 0 and 1; dividing by 1; multiplying together 3 numbers. Mulitply and divide numbers drawing mentally drawing upon known facts. Perform mental calculations, including with mixed operations and large numbers. Use a fact Use a fact Use a fact Use a fact 20 x 3 = 60. 63 ÷ 9 = 7 Use this fact to work out 126 ÷ 9 = 252 ÷ 7 = 3 x 75 = 225 Use this fact to work out 450 ÷ 6 = 225 ÷ 0.6 = 12 x 1.1 = 13.2 Use this fact to work out 15.4 ÷ 1.1 = 27.5 ÷ 1.1 = Use this fact to work out 21 x 3 = 22 x 3 = 23 x 3 = 24 x 3 = To multiply by 25 you multiply by 100 and then divide by 4. Use this strategy to solve 48 x 25 78 x 25 4.6 x 25
