Great trick for teaching how to make Students use a highlighter to find the and then circle the other number with a crayon. Although, I think it would be easier to always make 10 with the larger number, not necessarily the first number in the equation.
Rainbow to 10 anchor chart. Great for students learning addition. Also would be great for teaching addition of integers. i have never seen anything like this it is great if for if a child has trouble grasping the concepts of addition and subtraction
