Did your students forget to bring their protractors to class again? Using this resourceful copy of four identical protractors, you can easily make a class set or let your students take them home. 

Sixth graders investigate triangles and the inequality theorem. They will collaborate in groups to determine the length of a longest side of a triangle. Then relate the size of the triangle to its angles using protractors, yard sticks,...

Get out those protractors! From any angle, this activity will give your mathematicians some good practice. First, they find the measurement of eight angles. Next, they draw eight angles given the measurement. 

The first of two pages displays various angles as the measure of degrees of a circular arc. An explanation is written, and learners are asked to model each by holding up two pencils as the rays. The second page provides instruction on...

What does a geometric farmer drive? A protractor, of course! A set of assessment worksheets prompts learners to use a protractor as they measure angles, name angles, and identify lines. Use the video as a way to...

Why was the obtuse angle upset? Because it was never right! A valuable resource is loaded with background information on types of angles and lines. Learners review the characteristics of parallel, perpendicular, and...

Get out those protractors! Geometers measure interior and exterior angles of 10 polygons, including a 24-gon. They also calculate the interior angle sum of the polygons. 

Test young mathematicians' knowledge with an assessment aligned to California's fifth grade state standards. The exam covers a multitude of concepts including fractions and decimals, positive and negative numbers, measurement; and...

Rays and angles and Star Wars? It sounds strange, but it's actually a fun game to help fourth graders get good at measuring and identifying angles and rays with a protractor. Each pair of children chooses which Star Wars character they'd...

Where do the commas go? Kids rewrite a series of sentences using commas to set off the appositives in each sentence.

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Eleven questions make up an eight-page practice exercise that focuses on how to compute exchange rates. Money used is the American dollar, Euro, and British pound. 

Learners study acute triangles. They measure angles using a protractor, then classify the triangles as either right, obtuse, or acute. Everyone creates a design for a Navajo rug using only acute triangles.

Learners build confidence working with geometric tools and develop their construction techniques in the sixth lesson plan of the 29-part series. Given a geometric description, they use a compass, protractor, or ruler to create it....

Young scholars measure angles.  In this angle instructional activity, students draw angles.  They  use a protractor to measure angles and identify the angle as straight, right, acute, or obtuse. 

Tenth graders construct geometric figures using compasses and protractors.

Fifth graders explore the three types of angles. In this math lesson, 5th graders estimate the measure of angles and draw the angles using a protractor.

In this line segments and angles instructional activity, students solve problem solving problems and multiple choice questions about line segments and angles. Students complete 7 pages of problems.

Students discover rules for single transformations, rules for composition of transformations, when a figure has transformation symmetry, and if a transformation is congruent to its preimage.

Young mathematicians learn to see geometry from different angles with this simple printable resource. Providing multiple visual examples of angles, this simple document can be used as an instructional tool, a skills practice...

Learners calculate volume using the correct formula and the correct unit. They explore different prisms, spheres, cubes, and cones as they calculate volume and relate it to depths in oceans.

Fifth graders practice measuring angles by using protractors.

Through an interdisciplinary lesson, emerging engineers explore the history of surveying systems. After discussing various systems, they perform surveys on printable pages. Using their geometric skills, they physically stake out plots...

When told to describe a line, do your pupils list its color, length, and which side is high or low? Use a worksheet that engages scholars to properly label line graphs. It then requests two applied reasoning answers.
