A fun math game: Great for Whole Class and Small Guided Math Groups

I saw this great math game that builds flexibility. I have adapted it a bit but it basically goes like this:
  • Start Here. ..End There!” (Petreshene, 1985): give the students a pair of numbers and they have to keep making them in different ways.  For example,  “if you give the students 3 and 24 they have to come up with ways to make it work, by following a specific order. They can use any combination of addition, subtraction, multiplication, and division. For example, if the designated numbers are 3 and 24, some possibilities would be:
  • 3×8 = 24
    3×9-3 = 24
    3+10+10+1 = 24″

    You can do it with smaller numbers for primary grades where they would use just addition and subtraction.  For example,

    2+2+8 =12

    2+3+9= 12

    2+4+4+2 =12

    2 + 5 + ….. and so on

    Try it and let me know how it goes with your students!
