This lesson requires a worksheet that is not connected. It is integral to the lesson.

In this tangent circles instructional activity, students use pi to solve a problem involving tangent circles.  This one-page instructional activity contains 1 problem.  The answer is provided at the bottom of the page.

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.

In this science worksheet, young scholars look at the information carefully in preparation for a formal assessment. The focus is upon defining different aspects of air masses.

Second graders investigate friction by pulling a cup of marbles across a variety of surfaces, without the marbles spilling out.

Students explore the concept of triangle inequalities.  In this triangle inequality lesson, students cut spaghetti noodles into given lengths.  Students use the noodles to complete a worksheet about triangle inequalities. ...

Eighth graders engage in a lesson that is concerned with examining two dimensional figures with different properties that include circles, triangles, queadrilaterals, etc... They identify the types of figures that is identified as polygons.

On this interactive website students practice various math skills using a real life scenario. Those skills include finding angles, drawing angles larger or smaller than a given angle, and locating right angles.

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...

In this task, 8th graders are presented with a drawing of two parallel lines connected through two line segments. They are given the measures of two angles and are asked to find a third. Aligns with 8.G.A.5.

In this instructional activity, students explore different polygons by drawing them, measuring angles, and manipulating interactive sketches to find the angle sum for any polygon. Students also explore the angle measures in regular...

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

This lesson plan provides students with an opportunity to practice drawing and measuring triangles and angles. It also shows pictures and gives definitions of each type of angle and triangle.

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.
