With the implementation of Common Core, students have the benefit of learning math in a way which starts visual and concrete before moving towards the abstract. This is Stage 2 of a 4 stage unit that guides students through the steps of four developmental learning stage.
The full unit, Progressive Stages of Common Core Math: 2-Digit Addition with Regrouping- Stage 2,
consists of the following four stages:
Stage 1: Break Addends into Tens and Ones
o Visual teaching that uses ten frames or base 10 blocks to create a pictorial representation of this math concept.
Stage 2: Beginning to Add by Place Value
o An introduction to the concept of adding by place value that teaches adding in parts.
Stage 3: Adding by Place Value
o Continues to focus on numbers that are more easily added by students. It is the method often used when teaching mental addition.
Stage 4: Column Addition
o The algorithmic method typically used to perform 2-digit addition with regrouping.
Math really can be made easy for almost every child. I hope these stages of learning help you to more easily and confidently teach students how to successfully add 2-digit numbers. The step-by-step teaching sheet of each stage will also help your parents to better understand Common Core approaches to teaching and learning.
