Demonstrate an understanding of equations involving symbols to represent an unknown value by: writing an equation to represent a problem, solving one step equations. • Explain the purpose of the symbol, such as a triangle or circle, in an addition, subtraction, multiplication, or division equation with one unknown (e.g. 36 ÷ ? = 6). • Write an equation in symbolic form for a given pictorial or concrete representation. • Identify the unknown in a story problem, represent the problem with an equation, and solve the problem concretely, pictorially, or symbolically. • Create a problem in context for an equation with one unknown. • Solve a one-step equation using manipulatives. • Solve a one-step equation using guess and test. • Explain what is meant by "one-step equation with one unknown". • Represent and solve an addition or subtraction problem involving a "part-part-whole" or comparison context using a symbol to represent the unknown. • Represent and solve a multiplication or division problem involving equal grouping or partitioning (equal sharing) using a symbol to represent the unknown.
