How can you tell they’ve got it: Expressions & Equations Vocabulary?

If they’ve got it, you’ll see things like: Define and distinguish between expression, equation, and inequality; Identify terms, coefficients, and factors in algebraic expressions; Use the vocabulary of algebra precisely in mathematical discussions. Or just try it together: Can your child explain the difference between an expression like "3x + 2," an equation like "3x + 2 = 11," and an inequality like "3x + 2 > 11"?

Mathematics Algebra Ages 11–12

Expressions & Equations Vocabulary

Your child knows an expression like 3x + 2 has no equals sign. An equation like 3x + 2 = 11 does, and an inequality uses > or <.

In curriculum terms

Understand and use the concepts and vocabulary of expressions, equations, inequalities, terms, and factors; distinguish between an expression (no equals sign), an equation (equals sign), and an inequality (inequality sign)
