These 8 task cards just involve addition and subtraction of whole numbers -- but don't let that fool you, they are challenging.
With each puzzle you have three sums, you must find three numbers which will simultaneously yield the correct sums to complete the puzzle.
Students will need some counters to move around between the rectangles -- they will be deeply involved in solving each puzzle!
A student response sheet is provided, as well as a solution key for teacher.
Enjoy this FUN set of puzzles. Mary Alice Hatchett
