Lesson details
Key learning points
- Change can be described using multiplication or division. Division can be represented as multiplication by a fraction.
- The sentence 'The __________ is ___ times the size of the __________' supports us to describe a comparison or change.
- If units are different, we should convert so that they are the same - this supports us to calculate.
- To find a missing factor, we can divide the product by the known factor.
Keywords
Bar model - A bar model is a pictorial representation of a problem where bars are used to represent the known and unknown quantities.
Multiplicative - A multiplicative relationship is a comparison between numbers that relates to multiplication (and hence division). In a multiplicative relationship, the parts are equal.
Times the __________ - Times the __________ is a phrase that is used to compare measures multiplicatively. For example, one tree might be 'three times the height' of another tree - it is three times as tall.
Common misconception
Manipulating equations can result in errors.
To find a missing factor, we can use known facts where applicable, or we can divide the product by the known factor. Always encourage children to describe each part of the equation and what it represents.
