Chancery Flats Detention Basin: A Grade 7 Inequality Lesson
A 50-minute grade 7 math lesson where students write and solve inequalities for how long a fictional town's stormwater basin can fill before it overflows.
Common Core Math · Grade 7
7.EE.B.4 Construct and solve equations and inequalities
Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.
Why water teaches this standard well
Students write an inequality limiting the number of showers a household can take per week to stay under a monthly gallon conservation target, then solve it to find the maximum. Turning a conservation goal into a solvable inequality is a genuine planning tool, not just a textbook exercise.
Materials tagged with this code are written to the full standard , and each carries a written note explaining the alignment. See how we review materials.
