In this angles instructional activity, students solve 20 problems pertaining to angle measurement and classification. This page is intended to be an online activity, but can be completed on paper.

In this angle classification worksheet, students solve 8 problems in which an angle measurement in degrees is analyzed. Students classify each angle as right, obtuse, or acute.

In this angles activity, students answer multiple choice questions about angles on their own and angles inside shapes. Students complete 10 multiple choice questions.

In this measuring angles worksheet, learners complete a set of 10 multiple choice questions, clicking on a link for answers or to print the page. Worksheet is labeled "pretest."

In this angles worksheet, students answer multiple choice questions about different types of angles in shapes. Students complete 10 questions.

Students explore the concept of angles by interacting with numerous types of measurements. They create index cards with different angles. Then they pass the cards around to other students for comparison and measurement. They practice the...

 In this geometry lesson, learners read The Greedy Triangle and use geoboards to construct geometric shapes. They identify the number of sides and angles each shape has.

In this types of angles instructional activity, students identify types of angles as either acute, obtuse, straight or right. A reference web site is given for additional activities.

In this angles worksheet, students measure and label angles as either acute, right, obtuse or straight. A reference web site is given for additional activities.

Middle schoolers work to find and reinforce concepts related to lines and angles. They identify the characteristics of shapes that have one, two, and three dimensions. The students also work on definitions related to the geometry of shapes.

In this angles worksheet, students use a protractor and measure a set of 5 angles, checking the correct measurements and labeling as acute, right, obtuse or straight.

Students create different angles and shapes by using different lengths of straws. In this geometry straws lesson plan, students glue straws onto paper and define what they have made.

There is no such thing as someone who is not artistic when using this app. In fact, this is the type of app that makes you want to go out and buy a tablet computer. Whether you have a creative lesson planned, or just need a place to take...

In this angle worksheet, learners complete a set of 10 multiple choice questions. An answer link is provided; page is labeled as a "post test."

Students examine the correlation between art and math. Using their computers, students construct and measure angles. Students identify the properties of angles and polygons. They engage in the Angles program on their Palm and use the...

In this angles worksheet, students identify a set of 4 given angles as either obtuse, acute, right or straight, checking the correct box next to each. A reference web site is given for additional activities.

Scholars explore triangles with rods of different lengths. Using rods of 2, 4, 6, 8, and 10 cm class members build as many different types of triangles as they can. They also describe properties of these triangles and determine...

Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

In this word search worksheet, students locate 7 types of triangles. Triangles include isosceles, acute, equilateral, right, and obtuse.

Jam on with this multi-faceted activity teaching triangle classification. Start with a learner-paced lesson describing the different qualities of triangles and follow with a fun karaoke session. Also provided are two types...

A six-page packet walks, or bends learners through angles that combine to create triangles. Definitions are given for right triangles, obtuse and acute triangles. They draw angles according to directions, using a protractor to meet the...

Students discover that side measurement is used in determining angle classification of a triangle. By squaring sides, they predict whether triangles be right, obtuse, or acute. They prove the Pythagorean Theorem and use it to solve...

Students are introduced to some basic concepts of geometry. They explain that the definition of a triangle is a figure with three sides, three angles, and three points. Triangles can be named by using three points in their correct sequence.

All the 2-D and 3-D measurement work you need is in one location. Divided into three sections, the geometry lesson plans consist of visualization of three dimensions, classifying geometric figures, and finding surface area and volume....
