Grade 7 Math Worksheets

Represent the sample space of a two-stage event as an organized list, a table or a tree diagram, and see why the number of outcomes multiplies.

Design a simulation for a real situation — say what one trial is and how to read it — then use the trial results to estimate a compound probability.

List every outcome of a compound event in an organized table, then count the favorable outcomes to find the probability.

Use a scale to find actual lengths, perimeters and areas from a scale drawing, and redraw a figure at a different scale.

Given three sides, three angles, or two sides and an angle, decide whether the conditions give exactly one triangle, more than one, or none at all.

Name the two-dimensional shape produced by slicing a right rectangular prism or pyramid, parallel to the base or vertically.

Find the circumference of a circle from its radius or diameter using C = 2 pi r.

Find the area of a circle from its radius or diameter using A = pi r^2.

Use complementary (sum 90) and supplementary (sum 180) angle relationships to find an unknown angle measure.

Multi-step real-world problems on objects composed of several shapes — an L-shaped plot, a triangular prism, a room to paint — including the cost or quantity the answer is really for.
