Use this subtraction slide with manipulative counters so students can develop a better understanding of subtraction. Start with your equation in the bottom left corner (red box). Next add the top whole number of items to the top of the slide (green). Using the counters, slide the number of items you are subtracting down to the 2nd box (blue). Finally, move the remaining counters to the yellow box to get the difference. All boxes are color coded to help students sort their numbers. Great for individual use or centers.
