Use a protractor to construct angles. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Draw a triangle with exterior angle. Measure the exterior angle and each remote interior angle. Use the Alpha hand to check that the sum of the remote interior angles is always equal to the exterior angle.

This App contains five games that reinforce skills from the number and operations, geometry, and measurement standards. These games help students build skills in ordering numbers, choosing equivalent fractions, estimating and drawing...

Students learn to use drawing and measurement tools to measure angles. They explore and review types of angles as their measurements are altered.

[Free Registration/Login may be required to access all resource tools.] In this learning module, students are asked to match a given angle measure with one in a drawing. Includes video demonstrating a sample problem [2:14] and a set of...

In this activity, use an interactive, and investigative approach to determining the sum of the interior angles of a quadrilateral. They use Cabri Jr. to draw, measure, and calculate the characteristics of the angles of quadrilaterals.

The purpose of this task is to gain experience drawing and measuring angles, developing an understanding of the additive structure of angles. Aligns with 4.MD.C.7.

Students investigate the properties of angles inscribed in a circle. They use the drawing and measurement tools of Cabri Jr. to draw and measure certain angles, and establish the relationship between angles that intercept the same arc.

This activity is designed as an introduction to using the Carbri Jr. application on the TI-83+/84+ calculators. Students are guided through the menu system and are shown how to draw triangles, quadrilaterals and and a pentagon. Perimeter...

[Free Registration/Login may be required to access all resource tools.] Find interior angle measures of polygons by drawing diagonals to create triangles.

This site explains what the measure of the sum of exterior angles is for any polygon, and shows how to find the measure of individual exterior angles for regular polygons with a drawn example.

[Free Registration/Login Required] This flipchart is a look at angles in geometry. Drawing, labeling, measuring, special angles: (right, straight, acute, obtuse) and congruence.

Learn about drawing shapes using only a compass and straight edge or ruler with out measuring any lengths or angles.

Students, teachers, and parents alike will enjoy this challenging math site. It contains a clever brain teaser section plus creative problems related to algebra, geometry, measurement, numbers, statistics, and probability. A Spanish...

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,...

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...

Practice using your graphing calculator for drawing circles and for finding measurements for circles and parts of the circle. If you get stumped or if you would like to check your work, then select the View Solution button, which is...

[Free Registration/Login Required] This lesson lets students identify, draw, and measure parts of a circle. The lesson compliments 5th grade Harcourt Math, Lesson 23.4. Activote assessment is included at the end of the lesson.

This project resulted from the collaboration of a computer aided drafting teacher (pre-engineering), Chris Bond, and a math teacher, Lee Cable, (Hewitt-Trussville High School) to provide higher math expectations in CT and real life...
