Problem Solving Homework

Every year I have a huge focus on problem solving as a thinking skill and everyone asks for copies of the problems that I've used over the years. This problem is one of my favourites and is the first on the problem solving section of my website.

I have never seen it solved in one session so the kids and their family have seven days to try and solve it for homework.

Feel free to download this puzzle and have some fun thinking and being frustrated.
cheers

BTW This is a great activity if you are a casual teacher.
