Geometry worksheets for 3rd to 6th grade. A one-page lesson, How to Use a Protractor, and a guided practice sheet come before the protractor worksheet. Start with the chart of lines and angles, then name lines, rays and line segments, sort pairs of lines and kinds of angle, read a protractor, add angles and find a missing angle, find lines of symmetry, name polygons and work with ordered pairs on a grid. Younger children can start symmetry with the mirror image and draw the other half sheets, which finish a picture so both sides match.

Download PDFElementary geometry is mostly vocabulary with pictures. A child who can look at a drawing and say ray, perpendicular or obtuse has done most of the work, and the rest builds on those words. These sheets teach the words first and then ask children to use them.
The Lines and Angles Chart puts the words on one page, each with a picture and a short meaning. The next three worksheets practice them one group at a time: lines, rays and line segments, then pairs of lines, then the four kinds of angle. The figures are turned in different directions on purpose, because a right angle is still a right angle when it is not sitting flat.
A protractor has two rows of numbers, and reading the wrong one is the most common mistake. How to Use a Protractor shows the four steps: center mark on the vertex, zero line along one side, find the 0 on that side, then follow that scale to the other side. It shows the same 60° angle opening to the right and to the left, with the scale to read highlighted each time, and teaches a quick check: decide first whether the angle is acute or obtuse, so 60° and 120° cannot be mixed up. Using a Protractor: Guided Practice starts with the right scale highlighted, then leaves the choice to the student, and ends with angles where two readings are given and only one fits. No protractor is needed, because one is printed over every angle.
Measure Angles with a Protractor draws the protractor on the page, lined up correctly, so the only job is reading the scale. That is the step to learn before using a real one. Lines of Symmetry and Name the Polygons move from lines and angles to whole shapes. Before finding a line of symmetry, younger children can make one: the Mirror Image sheets mirror a picture square by square across a line, and Draw the Other Half asks them to finish a real picture so both sides match. More of these are in the activity sheets and the K-2 Puzzle and Brain Games pack.
Adding Angles and Find the Missing Angle are the 4th grade idea that angle measure adds up. When a ray splits an angle, the parts add up to the whole, so a missing part is the whole take away the part you know. Every figure is drawn at its true size, and the missing-angle sheet includes square corners (90°) and straight lines (180°).
The two coordinate grid sheets cover ordered pairs in the first quadrant: across first, then up. For shapes in more depth, see the lessons on types of triangles and types of quadrilaterals. There is also a printable protractor, blank coordinate planes, and worksheets on area and volume.
