Students classify prisms according to their attributes. In this classifying prisms lesson, students explore different prisms. Students generate observations of the attributes and classify the prism correctly.

For this polygons worksheet, students fill out a graphic organizer about the name of the polygon, the number of sides, the angle sums, and more. Students complete this for 5 polygons.

This amazingly extensive unit covers a wealth of geometric ground, ranging from constructions to angle properties, triangle theorems, rigid transformations, and fundamentals of formal proofs.  Each of the almost-forty lessons...

Learners explore pyramids. In this math lesson, students discuss where they have seen examples of pyramids. Learners classify pyramids as three-dimensional figures and identify their attributes.

In this interactive activity, students review attributes of equilateral polygons. They are introduced to the concept of a tessellation. Using protractors and pre-cut shapes, students arrange a variety of tiles to create tessellations....

Fifth graders explore polygons. In this math lesson, 5th graders find examples of regular polygons in the classroom and measure the sides of figures to determine if they are regular polygons.

Students are introduced to polyhedrons through using straw models to explore geometric solids and constructing Christmas tree ornaments using Epsom salt crystals. Students will view interactive videos and investigate and retrieve...

In this solid shapes worksheet, students read descriptions of solid shapes, then label a set of pictures with either box, cylinder, pyramid or cone. 

Students identify, compare and classify the various shapes. In this shapes instructional activity, students listen to descriptions of shapes with words such as sides, angles, congruent, and parallel. Students then give the teacher...

Students explore lines of symmetry. In this symmetry lesson, students divide and combine shapes along basic lines of symmetry. Students explore symmetry in real life objects.

Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.

Fourth graders examine the properties of geometric solids. Given geometric figures, they brainstorm observations. In groups, 4th graders identify solids and discuss the physical properties. Each student creates a Venn diagram and...

Fifth graders work with polygons.

Fifth graders explore polygons in various shape activities. For this polygons lesson, 5th graders discuss and identify polygons by their number of sides. Students sort ceramic tiles by the number of sides on each piece. Students explore...

Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...

In this word problem worksheet, 5th graders review various mathematical terms by selecting the correct letter that answers each question completely. There are a total of 13 math problems to solve which vary between word problems,...

Geometry adventurers study circumference of a circle as they listen to Sir Circumference and the Dragon Pi, by Cindy Neuschwander. In groups, they use string to measure the diameter and circumference of circular objects and...

In this elementary math worksheet, 4th graders practice solving problems for reviewing the concepts of number sentences, numeration, and geometry.

Students create an original lesson about geometry and angles. In small groups they take pictures using a digital camera of obtuse, acute, right, and straight angles that they find at school. Students use the photos in a computer...

Students explore basic geometry. In this geometry lesson, students study points and lines that exist in flat planes. Students investigate parallel and perpendicular lines.

In this Geometry worksheet, 10th graders solve a problems involving area of a circle given information regarding surface area.  The one page worksheet contains one problem with answer. 

For this geometry worksheet, learners practice finding the measure of 4 different angles. Students work independently as they refine their ability to correctly calculate the measure of an angle.

In this geometry activity, students identify radii, diameters, chords, tangents, secants and other terminology associated with circles.  The one page activity contains eighteen problems.  Answers are not provided. 

Don't go off on a tangent while writing equations of tangent lines! Scholars determine the equations for tangent lines to circles. They attempt both concrete and abstract examples, such as a tangent line to the unit circle through...
