Students need to know their addition combinations to ten, period! Here is a useful tool for coloring with two colors to show ways to make ten. Kids then add the equations (written both ways, such as 4+6 and 6+4), then fill out a number bond (10 in the big box, 4 and 6 in the small boxes). I hope you'll find it as useful as I do!
As requested, the file now includes adding to 2 thru 10!
