In this geometry worksheet, students identify the missing angles of non right triangles using the angle sum theorem. They solve for the unknown using algebra. There are 21 questions.

Sixth graders explore geometry by utilizing mathematical formulas. In this circumference lesson, 6th graders identify the difference between diameter, circumference and radius in a circle. Students review the formulas for finding...

Students solve problems using the unit circle. In this precalculus lesson plan, students identify angles using the properties of the unit circle. They observe the trigonometric graphs and sine, cosine and tangent.

Young scholars investigate polygons and construct ferris wheels. In this geometry lesson, students create a circle and differentiate properties of circles and polygons. They compare the relationship between angles and circumscribed...

Students investigate one, two and three dimensional objects. In this algebra lesson, students differentiate between different shapes of objects and write equations to represent each. They start with what they already know and prove...

Students measure and analyze angles. In this trigonometry lesson, students measure angles and distances use non-traditional techniques. They identify the different ratios of sine, cosine and tangent.

Learners use the axes and measure angle tool to explore and calculate complementary angles with Cabri Jr. They also identify what happens to the calculation as they drag the endpoint into a different quadrant. Finally, they label each...

Students find the diagonals of the quadrilaterals. In this geometry lesson plan, students identify and use properties of quadrilaterals. They define different parts of a quadrilateral shape.

Students create a scrapbook. In this geometry lesson, students use digital cameras to take pictures of geometrical concepts. Students use the pictures to create a "Geotown" scrapbook.

In this Algebra II worksheet, 11th graders review and apply the basic concepts for solving linear and quadratic equation. The one page worksheet contains twelve problems. Solutions are not provided. 

Students examine and identify polyhedron shapes on a math website. They write journal reflections about two- and three-dimensional shapes, and transform a square into a pinwheel.

Students explore the difference between drawing and constructing a triangle utilizing The Geometer's Sketchpad on the computer. They create, develop and script constructions for both isosceles and equilateral triangles. Each student has...

In this indirect Euclidean proof worksheet, learners write statements supporting the reasons for a given proof. This one-page worksheet contains ten problems.

For this assignment, math whizzes identify angles as either being obtuse, acute, right, or straight. Students identify six angles. The publisher states that this is designed with CCSS.Math.Content.MD.6 in mind, but it really does not ask...

In this word problem activity, students solve for the shortest distance between a spider and a fly.   The solution is provided.

In this geometry worksheet, young mathematicians divide a parallelogram into four, by choosing points along a diagonal.  Students calculate the area of each parallelogram and look for any patterns that may emerge.  The one-page...

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.

Students label three geological maps with continents provided to analyze the relationships between the movement of tectonic plates and the changes in the climate. In small groups, they discuss their findings and form hypotheses about the...

Fifth graders, after seeing Honeycomb examples, complete a Classifying Angles worksheet, Clock worksheet, and Defining Angles worksheet.

Fifth graders work with polygons.

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...

Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...

Fourth graders combine geometry and language arts skills while examining quilt-making. After identifying the geometric shapes contained in quilts, they write stories to encompass the quilt border. Students conclude by creating and...

Students follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the...
