This app allows students to quickly and easily memorize their addition facts. It also lets students, parents, and teachers keep track of which facts have been mastered and which ones need more practice.

As students answer questions, the system automatically records which facts were answered correctly but not quickly (yellow), which were answered incorrectly (red), and which were answered correctly quickly enough that they demonstrated mastery with automaticity (green). That is the real goal: to master facts with automaticity which is where students demonstrate that they instantly know the answers without needing to think about them. The goal of this game is to make every box in the addition table green which means you have mastered every addition fact.

Addition fact fluency is extremely important. It gives students confidence and provides a strong foundation for more complicated math that comes afterwards.

Common Core Standard 1.OA.C.6 - Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
