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

 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.

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....

Here is a classifying triangles practice worksheet in which learners sharpen their problem solving skills as they solve six story problems.

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

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

In this classifying triangles worksheet, 6th graders write the type of triangle, acute, right or obtuse, for 9 pictures of triangles, answers included.

In this polygons worksheet, students use the parallel, acute, right, obtuse, straight, and reflex to describe the five shapes provided.

In this triangles practice learning exercise, students respond to 4 questions that require them to identify the pictured triangles as acute, right, or obtuse triangles.

In this angle activity, students 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.

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

For this triangle worksheet, students identify triangles as either, right, acute, obtuse, equilateral, scalene or isosceles. A reference web site is given for additional activities.

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 angles activity, learners identify a set of angles as either acute, right, obtuse or straight. A reference web site is given for additional activities.

In this triangles worksheet, students draw angles with given measurements and identify each as either acute, right, obtuse or straight. A reference web site is given for additional activities. 

In this triangle worksheet, students check the appropriate label for triangles: right, acute, obtuse, scalene, isosceles or equilateral. A reference web site is given for additional activities.

In this triangle worksheet, students identify given triangles according to their sides and angles. Afterward, students draw triangles to match given descriptions. This one-page worksheet contains 15 problems.

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.

Upper graders label four triangles and fill in the labels correctly. They draw three original triangles and answer the questions about them.

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...
