In this card-matching activity, students must find eight sets of four cards. Each card in a set represents the same simple or compound inequality in a different way:
- Solved: inequality notation < > etc.
- Solved: interval notation
- Solved: represented on a number line
Each card has a letter, and the letters on each matching set spell out a word to make checking easier.
Common Core Standard(s):
A-REI.3 Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
Teacher instructions and an answer key are included.
