Sparking Surprise: A Negative Number Game to Promote Productive Concepts of Addition and Subtraction

Julie Nurnberger-Haag, Jamie L. Wernet

Abstract


We describe  a game that uses inexpensive and accessible materials to encourage students to make important discoveries about integer operations. Go-High/Go-Low gives students studying negative numbers a fun way to not only practice addition, subtraction, and ordering numbers, but also to discover the surprising idea that subtraction can actually lead to a greater number, depending on the number subtracted.
