3 Part Math-solving 'big' math problems

Recently I visited a Gr. 7 classroom where students were working on a 3-part math problem.  These problems are completed in all grades, and are meant to challenge groups of students as they apply mathematical concepts to larger problems which require multi-step thinking.  There are many ways to solve these problems, and students learn about some of the different ways others solved the problems during a 'congress', where the class gets together and some students present their solution. This type of learning promotes a growth mindset in students (and also staff!)

It is fascinating to see how students think, and inevitably they have ways of solving a math problem that are completely different to what I would have done, or even thought of.

Below are 2 students working on their solution to determining the area of a 'new computer lab' at Charlton by deconstructing a hexagonal shape into shapes they have learned to calculate area from.

Doing this type of problem is not something I would be familiar with in my schooling.  It combines applying math concepts, flexible thinking, creativity, and communication skills in determining an answer.
