Lesson details
Key learning points
- Multiplication can be used to represent equal groups.
- The x symbol represents times.
- One number in the multiplication represents the number of groups and the other the number in each group.
Keywords
Groups / grouping - A set of things with an identity.
Multiplication - The basic idea of multiplication is repeated addition, adding a number to itself multiple times. The result of a multiplication is a product.
Common misconception
Children are not able to explain the multiplication expression.
Children are encouraged to identify exactly how the equation relates to the image. For example 3 groups of 2 shoes: 3 x 2 - with the questions ‘What does the 3 represent?’ ‘What does the 2 represent?’ ‘What does the 6 represent?’
Only when the expression is fully understood, is it introduced into an equation, with the equals sign and the product. It is a further description of the image. Take time in this lesson to ensure pupils can explain an expression in a range of contexts.
