What is it?

I'm a big fan of differentiating tasks by offering a range of prompts and alternative lines of enquiry, rather than setting completely different work for students of different abilities. Not only does this help to foster cohesion in the classroom, but it also allows students to switch seamlessly between tasks if they require more support or more challenge. And that is why I love this lesson.

Students all start with the same premise – to try to work out how much each type of earring costs, while practising key skills such as measuring, estimating, using formulae and much more. With subtle differences in price, shape and profit margins, you can easily deliver this lesson to students of different abilities within the same class.

How can it be used?

Take my middle-set Year 9s as an example. I started the whole class on the middle (orange) lesson. If I saw that students were struggling, I could either intervene myself, move students around or substitute their worksheet for the lower (red) one. Likewise, for the students who were excelling, I could substitute their worksheet for the higher (green) sheet.

Because the task looks so similar on all three sheets, switching them around did not have the jarring effect it might usually have. In fact, there are plenty of opportunities for students to support each other, regardless of ability, which makes this particular lesson all the more engaging.
