Twenty word problems, one stegosaurus, and a built-in check: if a part of the picture has no matching answer, students know to look at their working again. Students plan and solve multi-step problems with money and measurement contexts, including "how many out of 100 were sold, as a percentage?".

How it runs

One or two lessons of 45–60 minutes. Start with the learn page and the benchmark percentages (10% means divide by 10, 25% divide by 4, 50% halve, 75% is three quarters), work through the examples on the slides, then students solve the 20 problems and colour the picture. Finish with the "Where do we see percentages?" page.
