:"Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem."
Our Take: The second grader can choose from a variety of different problem-solving strategies when solving one- and two-step addition and subtraction word problems. Some of these strategies may include base-ten drawing, open number line, or writing a number sentence. The computation difficulty increases in second grade as students are challenged to add and subtract within 100.
