Help 9th graders identify lines, points, rays, and planes in geometry. They  practice identifying, measuring, and drawing angles of different degrees. This is a fundamental lesson to help students learn the building blocks of geometry.

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

Young scholars draw and measure angles. In this angle measurement lesson, the teacher demonstrates how to form and measure angles while explaining the parts of an angle, then students practice.

Challenge your classes to combine geometric and algebraic concepts with an activity that builds on concepts learned in the first three lessons of the series. The fourth part asks scholars to identify geometric angle relationships and use...

Young mathematicians practice measuring acurately with a protractor. They convert measurements using a scale factor, then translate the new information into diagrams. This lesson should be a hit in that it's mostly hands-on work with the...

Sixth graders identify and measure right, acute, obtuse, and straight angles. In this geometry lesson, 6th graders review the definition of each angle and are shown examples of each specific angle. Students use toothpicks, gumdrops, and...

Young scholars investigate geometric relationship using conjecture about linear pairs and vertical angles. In this geometry lesson plan, students apply their theorems and previous geometry knowledge to solve for and find angles...

Explore types of angles and the characteristics of each. After observing a PowerPoint Presentation, learners tour the school facilities and use a digital camera to capture prescribed angles. Using the digital pictures and written...

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.

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

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....

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.

Students analyze a drawing of a regular octagon inscribed in a circle to determine angle measures, using knowledge of properties of regular polygons and the sums of angles in various polygons to help solve the problem. They use...

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

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

Introduce your young geometers to Hypatia, the first noted Greek female mathematician, and the properties of angles. Though this resource is missing worksheets that are needed to complete the activity, the structure is sound and learning...

Your class will investigate the relationship among different triangles. This geometry instructional activity, demonstrates how to make a connection between triangles and the Pythagorean Theorem. They identify the missing side or angle of...

Give every type of learner in your physics class an opportunity to demonstrate what they have learned throughout the year. From analyzing tables and graphs to evaluating diagrams and solving problems, there is an outstanding variety of...

High schoolers follow the directions on the attached worksheet to construct shapes using Geometer's Sketchpad. To start the lesson, it is suggested that the teacher guide the students through the initial problem. When constructions are...

In this geometry instructional activity, students calculate unknown angles in diagrams of 3 triangles. They draw and answer short answer questions about angles. They then calculate the designated angles in 2 more diagrams.

Students find missing angles and sides of triangles. In this geometry activity, students create intersecting lines to measure angles. They use Cabri Software to create virtual angles.

Students investigate points and angle bisectors. In this geometry instructional activity, students define angles, bisectors and perpendicular bisectors. They analyze angles and bisectors using Cabri software.

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Ahhh the vanishing point! Sounds ominous, but it's not. Fifth graders analyze the use of perspective in Renaissance art. They practice using linear perspective to draw railroad tracks that seem to go on forever. Tip: Make this...
