Equivalent and simplified ratios

A complete lesson on generating equivalent ratios and simplifying a ratio.

Activities included:

Starter:
A set of questions to remind pupils how to find equivalent fractions and simplify fractions. I always use fraction equivalence to introduce ratio, so reminding pupils of these methods now helps them see the connections between the two topics.

Main:

• A matching activity where pupils pair up diagrams showing objects in the same ratio.
• Examples and quick questions on finding equivalent ratios (eg 2:5 = 8:?)
• A matching activity on the same theme.
• Examples and a set of questions on simplifying ratios.
• A challenging extension task, using equivalent fractions in a problem-solving scenario.

Plenary:
A final odd-one-out question to reinforce the key ideas of the lesson.
