These Centers go along with Common Core Standards (for subtraction) 1.OA3 and 1.OA6.
These are the Centers:
• Subtraction Problem Match-Up
• Subtraction Game
• Find the Subtraction Facts for the Fact Family
• Subtract and Write
There is a Center card for each Center. There are also 66 subtraction problem cards and 66 answer cards that are used for the Centers. There is a gameboard in color and one in black and white for one of the Centers. I have laminated the pieces for my class and the students use vis-à-vis markers, which wipe off when they are done.
