This is a great activity for students to practice basic subtraction facts up to 20. It can be used around any patriotic holiday: President's Day, July 4th, Veteran's Day, etc. Once the students have solved all of their problems, they will color the boxes depending on their answer. On this activity, the even answers will get colored red, the odd answers that are less than or equal to 5 will be blue, and the odd answers that are greater than 5 will remain white. When students are finished, they should have a completed picture of the American Flag.
I hope your students enjoy this activity!
