MYP Assessment + GRASPS for Maths

For upcoming subject retreat days I put together a presentation about assessment. It includes diagnostic, formative and summative, as well as showing teachers how to use G.R.A.S.P.S. to create authentic/meaningful tasks.  This is just a short presentation and there is so much more I could add, but I didn't want to overwhelm.

I worked with the subject coordinator for math, and she said she is keen to focus on GRASPS for her upcoming assessment day. I had a stab at turning some activities/ideas/themes from some of the textbooks they are using into GRASPS activities. Any feedback would be wonderful, as I am not a math teacher! Consider these examples a work in progress! GRASPS for Math.
