I work in a new-ish school in NZ where we group and differentiate school-wide. I am laminating the question sheet to keep with me as prompts for my teacher rotations. This is going to be my mainstay for the second term as last year I found the differentiation worked amazingly and kept most of the discipline problems away. I love the examples too - I'm going to have to rewrite a few of my old instruction sheets now I've seen what the gold standard looks like! Great job.
