Operations and Algebraic Thinking

Narrative for the (OA) Operations and Algebraic Thinking

Algebraic thinking is about generalizing arithmetic operations and operating on unknown quantities.  It involves recognizing and analyzing patterns and developing generalizations about these patterns.  In algebra, symbols can be used to represent generalizations. Operations and Algebraic Thinking deals with the basic operations - addition, subtraction, multiplication, and division - the relationships they model, the kinds of problems they can be used to solve, as well as, their mathematical properties and relationships.

First grade students extend their Kindergarten work in three major and interrelated ways. These include representing and solving a new type of problem situation – comparison; representing and solving problems in which the result is unknown, the change is unknown, and the start is unknown. (10 + 2 = ___; 9 + ___ = 15; ___ + 14=20); and develop more sophisticated strategies to extend addition and subtraction problem solving beyond 10, to problems within 20.

Students in 1st grade begin developing an algebraic perspective many years before they will use formal algebraic symbols and methods. They read to understand the problem situation, represent the situation and its quantitative relationships with expressions and equations, and then manipulate that representation if necessary, using properties of operations and/or relationships between operations. Linking equations to concrete materials, drawings, and other representations of problem situations affords deep and flexible understandings of these building blocks of algebra. Learning where the total is in addition equations (alone on one side of the equal sign) and in subtraction equations (to the left of the minus sign) helps students move from a situation equation to a related solution equation.
