An all-encompassing package provides video clips that demonstrate real-world activities that have to do with angles. After watching the Cyberchase cartoons, learners discuss why a "v" shape is used to measure a turn. A pair of vital...

Build a solid foundation on which to develop future concepts. Through a guided exploration, learners compare and contrast the characteristics of points, lines, planes, rays, and segments. They measure lengths and practice notation for...

Light can be a mysterious phenomenon. Take away some of the mystery with an intriguing video lesson. The 38th lesson of the Crash Course physics series studies the movement of light waves. Topics include refraction and reflection as well...

Take one angle and get two. The presentation provides the steps required to copy and bisect an angle. Pupils follow the steps to create the two constructions. They create their own foldable to keep track of the steps for each construction.

Can you define that basic figure? Building upon the undefined terms in geometry, the lesson plan defines basic geometry figures. The resource defines line segment, ray, angle, perpendicular lines, and parallel lines.

Geometry begins with a point. The video introduces the concepts of points, lines, and planes. Using diagrams, the presenter includes how to name the objects along with how to write the names. Previewing the concept of 3-D space ends the...

Angle ABC is not the same as angle BCA, but it is the same as angle CBA. Help your classes understand naming conventions of angles and, more importantly, the importance of naming angles correctly. Scholars practice the parts of the angle...

Take a look at the definition from a different angle. The short assessment asks pupils to develop a precise definition of an angle. The scholars draw and label and angle to assist with the definition.

Investigate dilations to learn more about them. The second segment in a series of 16 provides a discussion of properties of dilations by going through examples. The problem set provides opportunities for scholars to construct dilations.

Mathematicians use notation for efficiency, so make your classes more efficient! The instructor explains the definition and notation for key elements of geometry such as points, lines, and planes. This is the 37th lesson is a series of 40. 

I spy a spine. The 19th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program explores vertebrate species, such as sharks and other fish. Learners take part in an activity evaluating the...

An informative lesson begins with a concept video explaining how radians are figured. Then it offers videos of four progressively difficult guided practice problems.

Practice those protracting skills while watching the step-by-step guide on the correct way to use this angle measuring tool. The resource follows with assessment questions testing their ability to understand and use the protractor...

Study concave and convex mirrors with an in-depth slideshow presentation. Slides contain term definitions as well as labeled diagrams.

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...

Set your pupils up to start on geometry by teaching them some introductory terminology. Pupils learn the terms by reading a short passage and looking at examples. They then respond to five questions related to the text.

Help young mathematicians shape their understanding of geometry with this series of worksheets and activities. Starting with an introduction to line segments, lines, and rays, the first unit in this math series continues on to explore...

An angle is formed when two rays share a common endpoint. Want to know more about angles? There are a lot of terms in this lesson. You might have to watch it two or even three times to make sure you understand all the terms. I recommend...

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...

Sixth graders revisit geometry terms and discover new circle vocabulary such as point, line, segment, ray, and angle through a Power Point Presentation. After the class discussion, 6th graders practice finding a radius and diameter of a...

This is a lengthy overview PowerPoint that defines, explains, shows examples, and has practice problems about points, lines and planes.  The class will need to write many notes and there is an example of how to set up in the Cornell...

Find here a creative approach to reviewing lines, line segments, points, rays, and intersection. Riddle solvers answer questions or name parts of the figure that they have drawn by following directions at the top of the page. 

Here is an identifying lines, line segments, rays, and angles worksheet which has learners identify the figures by telling whether figures are right angles, less than a right angle, or greater than a right angle, identifying lines as...
