Maths workshop – Multiplication Tuesday 27 th April 2010

Counting groups of objects

Grouping objects Repeated addition: = 6

Arrays in real life

Arrays as a tool for solving answers 6 x 3 = 18 3 x 6 = 18

Solving multiplication problems How many legs on 6 spiders? Notation: 8 x 6 = Array: Using known facts: I know that 5 x 8 = 40, so 6 x 8 = 48 Jottings:

Ideas to help children at home Give each toy or family member a certain number of objects (e.g. sweets). How many altogether? Count in 2s, 5s, 10s and extend to 3s, 4s, etc. with KS1 children when ready, including using coins (e.g. counting repeated 10p coins) Count in regular steps along a number line or 100 square and look for patterns Look at examples of arrays. How can we count how many there are? Ask children to solve ‘real–life’ multiplication problems and explain how they solved it Encourage children to use their own jottings to record their work and help demonstrate their thinking Support older children with the ‘x’ notation
