A Grade 7 Mathematics exam - whether a state end-of-course test, a district benchmark, or a placement or credit-by-exam assessment - checks whether a student can work fluently with rational numbers, write and solve multi-step equations, reason about ratios and percents, handle scale drawings and geometric measurement, and draw informal inferences from samples and probability models. The Grade 7 Mathematics case studies are 5 cases and about 2,795 words.
