**Challenge Prompts** from **Andrew Stewart-Brown** provides just what the title says, a video prompt for students trying Maths Challenge questions. Several papers are covered for the **Junior** (JMC 2014-2019) and **Intermediate** (IMC 2015-2017) Mathematical Challenges.

Students can select a paper to work on. They should work out the answer on pencil and paper then select their answer, if the answer is correct they can move to the next question. if students give an incorrect response they can watch a video prompt for that question. The video prompt reads the question and provides hints and prompts on how to solve it so students can then try the question again.

This is an excellent resource for students preparing for the Maths Challenges, but of course is also excellent for any student working on their problem solving skills.

Remember that it is possible to access **Maths Challenge questions by topic** for Junior, Intermediate and Senior from **Dr Frosts’s wonderful website** full of outstanding resources. Very conveniently it is possible to download **zip files of questions by topic**, choose a resource, for example, **Senior Maths Challenge questions by topic** and you will see the option to download all files.
