Matrix Inverse Coding Activity

This activity is designed for students covering FP3 to both practice calculating the inverse of a 3 x 3 matrix and extend into working with Matrix transformations and the inverse to reverse the effect of these. It is in the form of a codebreaking exercise, which you can give as much or as little help with as you see fit. It is a chance to have some fun and get the students working together to crack the code and get information out of you!
