In this angles instructional activity, learners answer multiple choice questions about different types of angles in shapes. Students complete 10 questions.

In this triangle worksheet, students calculate the measures of the angles or the sums of the measures of the angles in twenty-five triangle problems and hands-on activities.  The solutions are provided.

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

In this math worksheet, students determine the name for each triangle according to its classification. Then they create a truss construction model.

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

Fifth graders work with polygons.

Students review plane figures by playing a game that resembles "Twister." They listen to directions to locate a large example of the figure which is placed on the floor.

In this math worksheet, students look for the properties related to each shape and then fill in the graphic organizer with the categories needed.

Young scholars build polygons on their geoboards. In this geometry lesson plan, students build and then draw it on paper and label it. Young scholars then switch with a partner to try an make a symmetrical shape.

In this angles learning exercise, learners answer multiple choice questions about different types of angles and measurements of angles. Students complete 6 questions total.

Fifth graders create mathematical creatures. In this geometry lesson, 5th graders create a creature from regular and irregular geometric shapes. Students review vocabulary and construct an original creature based on a rubric.

Students investigate the Pythagorean Theorem. For this geometry lesson, students define angles and sides of right triangles. They calculate the area and surface area using formulas derived by the Pythagorean Theorem.

High schoolers calculate the different sides and angles of a triangle. In this geometry lesson, students use triangular properties to define the relationship between two triangle. They identify missing angles using the interior angle...

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.

Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.

Middle schoolers explore tessellations. They are shown a selection of shapes. Students identify shapes that tessellate and justify their answer. Middle schoolers create their own tessellation.

Students examine a selection of shapes and identify which shapes tessellate and why. They design and make a pattern which involves translation, reflection, or rotation. Students describe the features of 2-dimensional and 3-dimensional...

Students observe a selection of shapes. They identify which shapes will tessellate and justify their answer. Students apply the symmetry and angle properties of polygons to create tessellations.

Students use translations, rotations, and reflections to create tessellations. They explore and construct several different types of tessellations including pure/semi-pure and non-regular polygon and "Escher-like" tessellations .

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

In this math worksheet, students explore geometric shapes by completing a variety of exercises. Students label the pictures with the 3D shape names, draw radius and diameter lines, name different types of triangles and draw diagonals and...

This resource provides information about the altitude theorem for equilateral triangles, in addition to links on related topics. Requires Java.

Investigate the geometric definitions of triangles, focusing upon equilateral, isosceles, right, and scalene with detailed drawings and appropriate formulas for each. This site has links to more information on triangles.

This lesson will define scalene, isosceles, and equilateral triangles. It is 1 of 5 in the series titled "Scalene, Isosceles, and Equilateral Triangles."
