Students 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.

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.

Students measure and label specified angles. In this angles lesson, students use a protractor to find angles that are acute, obtuse, and reflexive. Students then label each angle and match the angles the correct definition. This lesson...

Sixth graders estimate the measurement of angles and then measure the exact distance using an angle ruler. In groups, they explore shapes and recognize the characteristics acute, obtuse and right angles. Students sketch required shapes,...

 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.

For 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.

Learners 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.

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

In this types of angles learning exercise, students identify types of angles as either acute, obtuse, straight or right. 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.

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...

With so many different types of triangles, it can be a challenge for young mathematicians to keep them all straight. Luckily this set of printable triangles is here to engage children in comparing and sorting triangles by their...

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

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

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...

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...

Young scholars 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...

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...

Students draw and calculate altitudes. They draw the altitude of acute, right and obtuse triangles and calculate the altitude of a triangle using the Pythagorean theorem.

Students measure the angles of a milk carton. They identify and label acute, right, and obtuse angles. Using appropriate tools, students determine the volume of a cube or a rectangular prism. Students complete worksheets to...
