This is a set of problems that get harder as you progress through the challenges. The idea is that they are family problems, so collaboration is the key. When we worked them out, there were a variety of different methods used; written calculations, drawings, jottings and bar models. The idea is that there is plenty of discussion, especially towards the end of the challenge. We really enjoyed discussing the different methods of solving the problems.
The questions are set by White Rose Maths and they invite you to share the answers with them. There is a link to the website below. Answers will be published about a week after the challenge has been set.
Have fun and good luck!
