Learners explore different types of quadrilaterals. Students define the terminology used with quadrilaterals. They create particular quadrilaterals based on specific characteristics of the quadrilaterals using an online tool.

First graders analyze characteristics of geometric shapes. They identify, describe, and create simple geometric figures. They analyze characteristics of geometric shapes and determine the defining attributes of a circle,...

Bring out the inner artist with this Abraham Lincoln lesson plan. Elementary students work on a home project creating a hat similar to Abraham Lincoln's hat. They will use geometry and measurement to create the scale of the hat, then...

Students follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the...

Students take an Internet field trip to research fractions. ESOL strategies include using pattern block manipulatives and pairing ESOL and non-ESOL students on computers.

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

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...

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

Students use their geometry and trigonometry skills to determine the distance between their school and another school.

Students develop an understanding of velocity and to distinguish it from speed. To determine the difference between a scalar and a vector quantity. To explore how acceleration is derived from velocity and time.

Pupils investigate the integrity and strength of different types of food wraps. They test the wraps and create a graphic organizer for the data. Once it is organized then a lab report can be written. The lesson contains background...

Construct parallel lines in Cabri Jr., and students label and check if all corresponding angles are congruent.

Explains the basic concept of parallel lines in Geometry with step-by-step instructions and methods for solving specific problems on your own relating to this topic.

Students explore relationships in various angles formed by 2 parallel lines and a transversal.

In this activity, students learn and increase their knowledge about the angles formed when parallel lines are cut by a transversal.

In this activity, students create parallel lines and a transversal, and study the properties of the lines and their angles.

This investigation uses Cabri Jr. and a cleaver rotation of a triangle to "prove" that the angles in a triangle add up to 180. This could be used to reinforce triangles and paralled lines as well as introduce the concept of rotating an...

Students construct a line parallel to the base of a triangle and measure the angles formed. They use the construction to prove that the sum of the measures of the interior angles of a triangle is 180 degrees.

This file contains questions related to parallel lines cut by a transversal and the angles formed. The questions can be used to asses your students' understanding of this topic in geometry.

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.

Study inscribed angles in semicircles and quarter-circles. What conjectures can you make about the measure of an inscribed angle in semi- or quarter-circles?

Consider two parallel lines that are intersected by a transversal, and when it crosses the two others, many different angle pairs are formed. See the special properties of the angle pairs in this interactive.

In this lesson, learners use line segments, angles, and parallel and perpendicular lines in order to create a one point perspective drawing.

In this instructional activity, students will learn important definitions about angles relationships an use those facts to solve equations.
