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...

Here is a geometry instructional activitywhich invites learners to create models using their knowledge of lines, segments, rays, and angles. This instructional activity reinforces geometric vocabulary and concepts through practical...

Students find triangular angles using the angle theorem. In this geometry instructional activity, students describe labeled triangles, use the pythagorean theorem, and rewrite information about triangles in standard form.

Fourth graders examine and identify line segments and angles using dot paper to draw them. They look at vertical, horizontal, intersecting, parallel and perpendicular lines, draw right angles and angles that are greater than and less...

In this triangles worksheet, students measure and calculate the measurements of eight triangles, their sums and classify the triangles as acute, obtuse or right.

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. 

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...

Third graders observe angles in their classroom and create an angle finder to represent them.In this angles lesson, 3rd graders classify angles as acute, obtuse, right or straight. Students find the differences and similarities in angles.

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.

Elementary schoolers examine the attributes of triangles. In this triangle lesson, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils draw multiple...

Young scholars find the orthocenter of a triangle. In this geometry instructional activity, students identify where the altitudes meet in a triangle. They use Cabri software to explore acute, obtuse and right triangles.

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

Students investigate triangles and their relationship to each other. In this geometry lesson, students solve right triangles using the properties of the Pythagorean Theorem. They differentiate between right, acute, straight and oblique...

After identifying angles (acute, obtuse, right) during a math or science lesson, 4th graders will use the computer to stamp pictures in the correct category using KidPix computer software.

Students examine the correlation between art and math. Using their computers, students construct and measure angles. Students identify the properties of angles and polygons. They engage in the Angles program on their Palm and use the...

The Common Core is intended to help all children meet high academic standards. Here is a Common Core designed lesson that is intended for learners with communication or language difficulties. The lesson is written in a narrative style...

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.

Students build polygons on their geoboards. In this geometry lesson plan, students build and then draw it on paper and label it. Students then switch with a partner to try an make a symmetrical shape.

Third graders recognize geometric shapes with acute angles, make geometric shapes with acute angles on geoboards, and draw acute angles on geopaper.

Young geometers investigate two-dimensional figures using coordinate grids. They identify polygons and draw examples of their reflection, rotation, and translation on a coordinate grid. And they complete a worksheet practicing examples...

Sixth graders identify and define a variety of triangles. In this identification of triangles lesson, 6th graders draw examples of each triangle on a whiteboard, then complete a worksheet.

Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...

Students find the different ratios of a triangle. For this geometry lesson, students use the Pythagorean Theorem to solve for missing sides and angles on a right triangle. They use a robot to create a right triangle.

Seventh graders explore basic geometric definitions involving angles, area, and circumference. To reinforce basic geometric concepts, they play a "lightning Flash" card game. Students discuss chores or jobs that require the use of...
