These butterfly addition cards are a great way to reinforce the Common Core skill of decomposing numbers in different ways! Each of the 9 butterflies has a number on his body, and an addition equation on each of his 4 wing segments. Students will solve the problems to see which equal the butterfly's number and which do not. Not only will they be practicing addition, but also eliminating incorrect answer choices, a test-taking skill every first grader is sure to need! I love to use these during our butterfly unit to show different ways to make a number. The record sheet makes it easy for students to organize their answers, and the answer key makes checking this center a breeze!
