The Grade 7 Math Proportions Quiz is a free web app for practicing proportional and inverse proportional relationships in a 4-choice quiz format.
All quiz questions, answer choices, hints, explanations, tables, and diagrams are original content created for this app.
The courses cover y = ax, y = a/x, xy = a, constants of proportionality, missing table values, coordinate points, graph shapes, and original word problems.
Hints change according to the current question and include simple SVG diagrams for lines through the origin, inverse proportional curves, table checks, and real-life situations.
Students can connect the same relationship in three ways: an equation, a table, and a graph. For proportional relations, they can check y÷x; for inverse proportional relations, they can check x×y.
The quiz also includes quick checks such as choosing the correct equation from a point, deciding whether a point is on a graph, and reading the shape of a graph.
Each question is short, so students can practice during a small break, before homework, or before a regular test.
