Product Description
Stop That Rat! ? Why would anyone want to "stop that rat?" Well, because it's really fun to watch your students work on this puzzle, which comes in gritty color as well as black and white. 63 pages of rat fun! Seriously, the basic puzzle is simple: take the disks which are numbered 1 - 6, and arrange them on the board so that each side adds up to 9. However, things get very interesting when you find out that you can re-arrange the 6 numbers to add up to 10, 11 and 12.

But it gets better than that: you can also change the numbers from 2 - 7, and it will add up to 12 through 15; you can also use the odd numbers (1, 3, 5, 7, 9, 11) which will add up to 15, 17, 19 and 21. You can also use the even numbers, as well as multiples of 5, and still have a really cool puzzle.

And it does not end there! I have included 11 different suggestions about how you can differentiate this puzzle, which would make it challenging to every single student in your class, whether it is the student struggling to add single digit numbers, to the one who is ready to think algebraically using patterns.

You should definitely stop that rat!
