Determine which angle has a greater measure by looking at the size of the opening between the angle's rays. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Although part of the Study Guide for the CAHSEE, this section of the document focuses on measurement and geometry. In the study guide, students are shown why this topic is important, how they will be assessed, and then given a long...

This activity is designed for students to make conjectures about triangles. Students will create three lists to represent the measures of the angles of the triangle. The entire class list will then be sent to each student for analysis,...

Rather than dividing a circle into some number of segments (like 360 degrees), mathematicians often prefer to measure angles using the circumference of a unit circle - a circle with radius 1. This way of measuring angles is called...

In this activity, students will practice some of the basic functions of the Cabri Geometry software, including use of the Pointer, Point, Line, Measure, and Construct toolbars.

If you want to plant a class garden, this is a great resource for combining geometry, Native American studies, and rocks.

The applets in this Interactive Geometry Dictionary (IGD) will show you how to find the area of some common shapes.

In this activity, students use the Cabri software to mark points, draw lines, construct parallel and perpendicular lines, angles, bisectors, and triangles. They learn how to use the tool to measure angles.

Students use the Cabri Jr. application to draw triangles and construct perpendicular bisectors on the sides of a triangles. They study the properties of a triangle and understand how the measures of angles of a triangle is always 180...

Convert within the same units of measurement.

Determine which measuring tool is best used to solve the problem.

Practice using your graphing calculator for Geometry problems. If you get stumped or if you would like to check your work, then select the View Solution button, which is located directly under each problem.

[Free Registration/Login may be required to access all resource tools.] This study guide looks at similar polygons, scale factor (ratio), and triangle similarity.

Record measurements in decimal notation.

Measure time intervals by choosing units of time.

[Free Registration/Login may be required to access all resource tools.] Learn how to solve problems using scale and indirect measurement.

Print or create worksheets or flashcards to assess students' understanding of angle measure, area, surface area, and volume.

In this inquiry-based lesson, students will work in groups to gather measurements needed to approximate the height of a building. Students will discover how geometric mean can be used to find the lengths of missing sides of right...

This site by Suzanne Alejandre offers lesson plans, activities and resources covering topics in algebra, geometry, data analysis, number & operations, and measurement. The contents of this site are aligned with the NCTM standards and...

Students work in groups to build their own kite. The activity explores estimation, geometry, measurement, and patterns. The resource consists of a lesson plan, group activity instructions, lesson overview, and an expert page.
