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.

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....

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,...

Sixth graders investigate different types of angles. In this geometry lesson, 6th graders use a protractor to identify acute, obtuse, and straight angles.

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

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

Students explore angle estimation and measurement. For this angle lesson, students define obtuse, acute, and right angles, and practice measuring angles using a protractor. Students participate in an online angle estimation activity.

Students measure angles using a protractor. In this geometry instructional activity, students solve for the missing angles using equations set to the theorem of triangles. They measure missing angles through construction and identify...

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...

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...

Scholars practice vector direction notation in multiple formats. After mastering each individually, they work to convert from one to another as one part in a series of lessons on vectors and projectiles.

The Kuril islands stretch from Japan to Russia, and the ongoing dispute about their jurisdiction prevents many scientific research studies. Scholars learn to create a topographic profile of a specific area around their schools. Then they...

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

Students investigate angles through construction. In this geometry lesson plan, students use a protractor to identify the measurement of an angle. They identify angles cut by a transversal and two parallel lines.

Students explore about triangles and their relationship to the worlld around them. They are able to identify triangular shapes in their environment. Students are able to communicate to one another their understanding of triangles outside...

Here is a good activity which invites learners to practice measurement using standard and nonstandard measuring tools. In this measurement activity, learners work with length, width, height, and area. They use standard and nonstandard...

Students examine a sample budget and categorize the entries as a group. Then in small groups they convert budget category totals to percents and degrees to make a circle graph related to a sample budget.

Students construct parallel lines using a protractor and a straightedge. In this geometry lesson, students identify the properties of parallel lines. They use Cabri to graph and observe the lines.

Tenth graders construct geometric figures using compasses and protractors.

Students make a circle graph. In this graphing lesson, the teacher conducts a class survey, then demonstrates how to make a pie graph. When students are comfortable with the material, they use a worksheet to create their own graph.

Students make constructions and conjectures. In this geometry lesson, students construct right, acute and obtuse angles using a straight edge and a protractor. They investigate parallel lines and the angles formed by the angles.

Learners create lines and shapes with a compass and a straight edge. In this geometry lesson, students investigate square roots, irrational numbers and spirals. They explore nature to see the shapes representing mathematics and geometric...

Young scholars review what they comprehend about angles. They name the differnt types of angles and define them. Students use their protractors to answer questions, the teacher walks around to look at the positioning of the...

Students view a PowerPoint for a warm-up lesson. They practice measuring around the classroom, measuring such things as the length and width of a desk, pencil, door, and book. Students use a website to practice measuring angles.
