Common Core Math: Kindergarten: Algebraic Thinking

In kindergarten, students conceptualize addition as "putting together" numbers and subtraction as "taking apart" numbers. Students represent addition and subtraction in a variety of forms, including by using concrete objects and drawing visual representations. Students learn to add and subtract within 10 and to describe a number as the sum of two smaller numbers. Ultimately, students are able to use addition and subtraction to answer questions about real-world scenarios.
