Math Instruction for Second Grade Addition and Subtraction

Introduction:

Once students have had success with number sense and concept of number in grades K and 1, it is time to introduce addition and subtraction.  The VA SOL for thread 2.5, states the students will recall addition facts with sums to 20 or less and the corresponding subtraction facts.  It is important that both addition and subtraction are taught together to help students learn the concepts and understand the process rather than just producing an answer without an understanding of why it works this way.  This setup and delivery of this skill is vital to the future success of any student in the undertaking of more challenging math concepts in the future.
