Geometry

Free 4th Grade Geometry Worksheets

This nine-week Grade 4 geometry program covers every Common Core geometry and measurement standard tested at this grade level, from basic figures to angle measurement to two-dimensional shape classification. Each week opens with a short concept passage and worked examples before students reach the independent practice — students see the reasoning behind each skill, not just a stack of drill problems.

What the nine weeks cover

The program follows a logical progression that mirrors how Grade 4 geometry is sequenced in most state standards documents. Week 1 establishes the vocabulary for points, lines, line segments, rays, and angles, which everything else in the unit depends on. Weeks 2 through 4 develop angle work: classifying angles as right, acute, or obtuse; using a protractor to measure and draw angles in degrees; and applying additive angle measure to find an unknown angle when a larger angle is split into parts (4.MD.C.5, 4.MD.C.6, 4.MD.C.7).

Week 5 turns to parallel and perpendicular lines, which the rest of the unit relies on. Weeks 6 and 7 use that vocabulary to classify triangles by angles and side lengths and to sort quadrilaterals into parallelograms, rectangles, rhombuses, squares, and trapezoids, including the hierarchical relationships between them (4.G.A.2). Week 8 covers lines of symmetry in two-dimensional figures (4.G.A.3). Week 9 is a cumulative capstone that mixes problems from every prior week, functioning as both review and an end-of-unit assessment.

Standards alignment

The worksheets target Common Core domains 4.G (Geometry) and the angle measurement strand of 4.MD. Specific standards addressed include 4.G.A.1 (draw and identify points, lines, line segments, rays, angles, and parallel and perpendicular lines), 4.G.A.2 (classify two-dimensional figures), 4.G.A.3 (recognize line-symmetric figures), 4.MD.C.5 (recognize angles as geometric shapes formed by rays sharing a common endpoint and understand degrees), 4.MD.C.6 (measure and draw angles in whole-number degrees using a protractor), and 4.MD.C.7 (recognize that angle measure is additive and solve unknown-angle problems).

How parents and teachers use these worksheets

Each week includes five practice worksheets with a full answer key, formatted as a print-ready PDF. The pacing assumes roughly one worksheet per day across a five-day school week, but the structure is flexible — families homeschooling year-round, classroom teachers building a unit, and tutors looking for targeted practice on a single standard can all pull individual weeks without missing context, because each pack begins with its own concept introduction.

The instructional passages are written at a Grade 4 reading level, with vocabulary intentionally repeated across weeks so students see terms like vertex, ray, parallel, and right angle in multiple contexts before the capstone. Worked examples model the exact thinking expected on the practice problems, which makes the worksheets usable for independent study and not only for guided lessons.

All nine weeks are free to download. No account is required.
