Author note — to cover

Solve linear inequalities in one variable with positive coefficients, e.g. 3x + 2 < 11 and 5x − 1 ≥ 2x + 8, keeping the inequality sign through each balance step; present answers as ranges like x < 3. Negative-coefficient flips, number lines and integer lists are the sibling pages. Both tiers. (A22)

• Fluency — direct questions on solving a linear inequality, limited to this lesson's stated scope (4 questions).
• Application — use the same skill in unfamiliar or contextual questions without introducing a later method (4 questions).
• Check — questions built around the exclusions and likely misconceptions named in the lesson brief (4 questions).
