Mathematical benefits

Three-In-A-Row supports students who have begun mentally subtracting numbers less than 15.  With each turn, children must consider several subtraction problems in order to be able to place their chip in a strategically beneficial spot.  Since this game allows students to create their own problem, they must consider the part-whole relationship of numbers.  When considering strategy, students will begin with a sum and have to work backwards – effectively thinking about the difference between two numbers.  This helps to solidify the concept of subtraction, and aids in overall mathematical fluency.
