This game is to promote automaticity with math facts. You can use it to review addition, subtraction, multiplication, or division. Place the bases (the pages with the motions) around the room in places where the students will have space to move. Line up the students in front of you. Use flashcards to show each individual student a math fact. The student will have 3 seconds to answer. If she/he gets the answer correct, she/he gets to run the bases. At each base (page), there is a different movement. Once the student has rotated through the bases, she/he returns to the line. I like to glue the pages to a paper plate to make them look more like baseball bases.
