I created this for my first graders to make adding more fun. I used different animals, with missing addends and missing sums. They color the animals and then count the colored animals to find the answer. They also color the animals, then write the equation to go along with each animal problem. So, they are required to find missing addends and sums, as well as write equations. Later, I took this further and made manipulatives out of the animal pictures, and let them use those to add instead of typical counters. They liked that.
