Simple Algebra

N.2. Algebra (NCTM)

2.2. Represent and analyze mathematical situations and structures using algebraic symbols.

2.2.3. Use symbolic algebra to represent situations and to solve problems, especially those that involve linear relationships.

N.11. Grade 6 Curriculum Focal Points (NCTM)

11.3. Algebra: Writing, interpreting, and using mathematical expressions and equations

11.3.1. Students write mathematical expressions and equations that correspond to given situations, they evaluate expressions, and they use expressions and formulas to solve problems. They understand that variables represent numbers whose exact values are not yet specified, and they use variables appropriately. Students understand that expressions in different forms can be equivalent, and they can rewrite an expression to represent a quantity in a different way (e.g., to make it more compact or to feature different information). Students know that the solutions of an equation are the values of the variables that make the equation true. They solve simple one-step equations by using number sense, properties of operations, and the idea of maintaining equality on both sides of an equation. They construct and analyze tables (e.g., to show quantities that are in equivalent ratios), and they use equations to describe simple relationships (such as 3x = y) shown in a table.
