OU: Developing Algebraic/Statistical/Geometric Thinking

[AirForce5]

Hi everyone,
I am starting the module Developing Algebraic Thinking in April, but there is one thing I am unsure of. The assignments will require me to have "access to learners of Maths Key Stages 2-4 (this may include adults)"
It doesn't say what the minimum group size is. I currently tutor a group of 4, would that be enough? I have no idea what is required for the assignments yet so any advice from previous students on this module would be great :)

I studied this suite of courses around 6 years ago. One learner is adequate and they can be adults you know, they don't need to be students.
I loved them all, geometry the most. I hope you enjoy them as much as I!
