This is a memory game for students are around 4th grade who need review with addition, subtraction, multiplication, and division fact families. It also includes what sum, difference, product, and quotient mean. It aligns with the Kansas State Standards for 4th grade. Some are easier than others so all students can participate and help one another! For the teacher: each card is next to its match on the original document. I put each set of cards on a colored piece of paper, laminated them, and put them in individual baggies so it was easy to distribute.
