Three similar activities which involve colouring in all the square numbers, cube numbers, and prime numbers in grids to demonstrate that all squares are of the form 4n or 4n+1, all cubes are of the form 9n, 9n-1, or 9n+1, and all primes (except 2 and 3) are of the form 6n-1 or 6n+1. PLEASE REVIEW / COMMENT.

Thank you great investigation for consolidation-with solutions sheets too.
I love this as an activity to use in the beginning of the year with my 7th grade pre-algebra students. It will help me to assess levels of knowledge and problem-solving that my students are bringing with them into our class. Plus this is a great way to generate primes and something ALL students will be able to do as we evaluate expressions during the fist marking period. I look forward to trying this next week!
