Welcome to THE Y5 Parental workshop Mathematics
Today we are going to be looking at teaching times tables Key steps Build the multiplication table Chanting times tables aloud Noticing and investigating Games 8 Times Tables
Build the multiplication table 8 x table Let’s start with 0 because zero times any whole number is zero. 0 x 8 = 0 I know 10 x 8 = 80 because a number multiplied by 10 moves one place to the left and has a place holder of 0. If I know that 10 x 8 = 80, then I can use halving to find 5 x 8 = 40
Build the multiplication table 8 x table 1 x 8 = 8 If I know 1 x 8 = 8 then I double it to find 2 x 8 = 16 Now to find 4 x 8 I can double 2 x 8 = 16 so 4 x 8 = 32 Now I can double again so if 4 x 8 = 32, 8 x 8 = 64

Build the multiplication table 8 x table I know 2 x 8 = 16, then I can add 8 to find 3 x 8 = 24 If I know 3 x 8 = 24, then I can use doubling to find 6 x 8 = 48. I can double again to find 12 x 8 = 96
Build the multiplication table 8 x table Now to find 9 x 8 I could add 8 to 8 x 8 Or I could subtract 8 from 10 x 8 Or I could add 3 x 8 and 6 x 8 I know that 11 is (10 lots and 1 lot), so 11 x 8 must be 80 + 8 which is 88 (10 x 8) + (1 x 8) = 11 x 8 9 x 8 = 72
Build the multiplication table 8 x table Now to find 7 x 8 I could add 8 to 6 x 8 … Or I could add 2 x 8 and 5 x 8 (2 x 8) + (5 x 8) = 7 x 8 7 x 8 = 56 The one the children always forget!!

chant the multiplication table 8 x table Let’s chant the multiplication table – Keep it lively! Zero times 8 is 0 One times 8 is 8 Two times 8 is 16 Say it in a squeaky voice, loud voice, funny voice etc. Chant table tennis.
noticing the multiplication table 8 x table Ask the children “What do you notice?” Look at the tens digit in the product: Multiplying by 1,2,3,4,5- the answer starts with one less. Multiplying by 6,7,8,9,10- the answer starts with two less. (8 x 3 = 24) (8 x 6 = 48) Every 5 rows, the ones digit follows the pattern: 8, 6, 4, 2, 0 This repeats over and over. They are all in the four times table All of the 8 times table are even.
