My grandson loved this...
This was an Easter gift for my grandson. He is 8 and loved doing the math to work the puzzle. I also gave him One Knight Too Many, Double Digit Decoders-Addition & Double Digit Decoders-Subtraction. He is anxious to do those too. I plan to use these this summer to keep his math skills sharp for next school year.

Fun learning and reviewing
Great summer activity. Fun so children don't really consider it math work. Keeps them from loosing what they have learned.
