Learners experiment with straight edges and compasses to divide lengths into equal parts. They identify different fractions of the total length.

Fifth graders use tan to solve problems involving right-angled triangles. They solve equations of the form tan(8) =a, for a between 180 degrees and 360 degrees. They state the value of tan (8) in special cases.

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...

Where do the coordinates lead? As children brainstorm ways to find the location of different buildings, they learn about coordinate points and how to use them to locate areas on a grid or map. They practice using ordered pairs by playing...

Fourth graders complete a variety of activities as they study the European exploration of the Midwest, focusing on Indiana. They map the path explorers took, comparing the British with the French. They research why the explorers stopped...

Sixth graders create a poster using one-point visual perspective. After exploring several examples of one-point perspective, 6th graders create a drawing around the theme of school community. Posters are illustrated and installed...

Material to supplement classroom instruction on parallel lines: a lesson on angles with parallel lines, a practice quiz, and a link to an investigation on angles with parallel and non-parallel lines.

Investigate vertically opposite, corresponding, and alternate angles formed by parallel lines and a transversal using this highly interactive Learn Alberta math. Be sure to follow the link to the printable activities, solutions, learning...

Try these three problems about finding the measures of different angles that arise from diagrams involving parallel lines and transversals. Detailed solutions are written out for these three problems of moderate difficulty.

Get the definition for parallel lines and explore angles associated with parallel lines.

Angles, parallel lines, and transversals are explained through examples and a video lesson. [1:01]

Explains angles and parallel lines through examples and a video lesson.

Find missing angles given two parallel lines and a transversal. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

At the end of this lesson, students will be able to identify and apply the properties of lines and angles and understand the concept of parallel, perpendicular, complementary and supplementary angles, vertical angles, and parallel lines...

A guide to support parents as they work with their students in angle measure and plane figures.

Students learn about parallel lines and pairs of angles. Definitions and examples are included.

In this practice activity, students calculate angles created when two parallel lines are intersected by a transversal. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.
