I created this resource for my mod-severe students who were having a hard time understanding the concept of adding numbers together. Often they would count the first number, stop, then go to the second number in a math problem and start counting at 1. Try using 2 different colored manipulatives or markings. Laminate and use with base ten blocks, math link cubes, other manipulatives, or simply use the grid to keep numbers lined up!Clipart credit: Krista Wallden - Creative Clips
