Students work with three dimensional objects. For this geometry lesson, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.

Ninth graders access a star worksheet and determine properties of polygons.  In this investigative lesson students complete a worksheet and discuss myths. 

Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

Students explore geometric concepts by working with Tangram Puzzles. In this Tangram challenge lesson, students use problem-solving tasks that involve physical manipulatives. Students select a picture and use all seven pieces...

Students discover patterns and write conjectures relating to perimeters and polygons. Working in cooperative learning groups, they use manipulatives and graphic organizers to solve problems then answer a series of questions in which they...

Fourth graders discuss characteristics of polygons and organize and visualize those characteristics using Kidspiration. Students import pictures that demonstrate the characteristics and save their projects to be reviewed and graded by...

Fourth graders discover that a polygon is a closed figure formed by line segments, and that the perimeter of a polygon is the sum of the lengths of its sides. They utilize a worksheet imbedded in this plan to gain lots of practice with...

In this geometry worksheet, students practice finding the area of 11 polygons using diagrams which include units in both standard and metric measurement. They solve for the area of 11 polygons using words that describe the polygons that...

In this geometry worksheet, students study diagrams with labels of common geometric figures. Students then answer 24 questions. Then they draw and label their own figures.

Use the alphabet as a tool for teaching your class about geometric figures. Break apart capital letters into line segments and arcs. Classify angles as right, acute, or obtuse. Identify parallel and perpendicular lines. An excellent...

In this measuring lengths learning exercise, students determine which units to use when measuring lengths, estimating lengths, and the errors made when measuring, Students estimate the lengths of each of the lines illustrate to the...

First graders find angles in their classroom. In this geometric figures lesson plan, 1st graders identify, describe and classify angles they see in their world. Students create pictures that contain angles and display them in the room.

In this patterns worksheet, students analyze a series of geometric shapes and determine the pattern. Students use numbers or letters to represent each pattern.

Sixth graders explore characteristics of similar objects. Using attribute blocks, they explore the ratios of the perimeter, area and side length in similar shapes. They calculate and compare the area of shapes.

Students classify polygons by name and shape. In this geometry lesson plan, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.

In this math worksheet, students sketch the finite area whose boundary is composed of pieces of the curves x =1− y 4 and x = y2 − 1.

In this spatial relations worksheet, students solve three-dimensional problems. They find the total number of triangles in a given figure, the number of line segments that endpoints and use integer points to solve two problems. This...

In this math activity, students examine the graph of the derivative. Then they determine the critical points that correspond to the relative extrema.

High schoolers explore the concept of logarithms.  In this logarithms lesson plan, students graph logarithms on their Ti-Nspire calculator.  High schoolers describe the shapes of their graphs by identifying slope, y-intercepts,...

Students explore arithmetic and numerical patterns. After observing a teacher created function box, students describe a pattern and predict what will "come out" of the function box. They explore patterns such as geometric shapes,...

In this math worksheet, students find the area of all the different types of geometric shapes from the memory. They write all the formulas and explain the meanings of the variables.

In this determinant worksheet, students explore determinants, area and volume. This two-page worksheet contains explanations and examples. It provides two problems for students to solve.

In this math worksheet, students match the drawings that are in pieces in order to create three dimensional geometric figures. They match the nets with the shapes.

In this street map learning exercise, students analyze a section of a street map of Washington D.C, finding parallel streets, listing streets that form given shapes, and following directions. Answers on page 2.
