TES Maths ROTW: GCSE problem-solving activity
TES Maths Resource of the Week
Resource title: GCSE problem-solving activity
Resource author: andy_gillen
What is it?
The first exams for the new GCSE specification are on the horizon and they will undoubtedly be more challenging than ever before. One thing I've noticed when looking through the sample assessment materials is that different topics will be combined together far more frequently.
This provides a problem for students who have learned and practised topics in isolation. If they are not able to apply different skills to the same question, then they are likely to come a cropper. Fortunately, resources like this will help students to gain that essential practice.
How can it be used?
In this unstructured problem, students are asked to work out the total surface area of a cone, cylinder and hemisphere. While this sounds easy enough, it is not enough to simply substitute numbers into a formula. Learners must call upon their knowledge of basic trigonometry, surface area, circumference, ratio and Pythagoras in order to complete this task successfully.
Pupils may find this difficult at first, so it might be worth preparing some hint cards, or using my counter technique, in which groups can exchange a counter for a question. Whatever you try, please persevere as it is essential your students develop the grit and determination needed to tackle problems like these.
