[Free Registration/Login Required] This flipchart introduces basic geometric shapes and gives students practice finding geometric shapes in everyday objects.

This SMART Notebook lesson allows students to characteristics of polygons by exploring vocabulary and sample problems.

The introductory pages introduce the shapes and their attributes: triangle, rectangle, square, rhombus, circle, and oval. The additional pages allow students to practice shape recognition, tracing shapes, and drawing shapes.

This is an inquiry lesson used to review Algebra 1 objectives by applying them to geometry concepts. Students explore the properties of quadrilaterals and classify them by definition. This lesson can be use in geometry classes. Students...

Discusses the radius, diameter, circumference, and area of a circle.

Defines polygons and explores characteristics, types of polygons, and how to calculate the area of a polygon.

Learn all about triangles with the help of this downloadable mathematics worksheet.

Given a verbal and/or pictorial description of the intersection of a plane with various three-dimensional geometric figures, the student will describe and/or draw the intersection.

Match 3D objects with their 2D cross-sections. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Basic practice problems involving cross sections of 3D objects.

Given a figure on the coordinate plane and a center of a rotation, find the angle for the rotation that maps one figure to the other.

Given two figures on the coordinate plane, draw the line of reflection that takes one figure to another.

This site presents information on the three basic transformations of figures in a plane: Reflections, Rotations, and Translations.

For students who have ever played dominoes and Tetris, polyominoes will strike them as a great deal of fun. Teachers will see the educational benefits of working with similar and congruent shapes and rotating them in a plane. Exploration...

Students understand that a tessellation is covering of a plane with a pattern of figures so there are no overlaps or gaps. They draw quadrilaterals and triangles and explore monohedral, dihedral, and trihedral tessellating patterns.

Given examples of mathematics in the real world, the student will use properties of transformations and their composites to describe and perform transformations of figures in a plane.

Given a pair of figures in the coordinate plane, try to map one onto the other and determine whether they are congruent. Includes examples of glide reflections. Students receive immediate feedback and have the opportunity to try...

Given a figure on the coordinate plane and the definition of a rotation about an arbitrary point, manually draw the image of that rotation.

Given a figure on the coordinate plane and the definition of a rotation about the origin, manually draw the image of that rotation.

Based off of the hit television show NUMB3RS, this lesson has students explore finding the centroid of an irregular polygon by finding the mean of the coordinates of the polygon's vertices. Further, students find the centroid given that...

The purpose of this task is to apply translations and reflections to the graphs of the functions f(x)=cos x and g(x)=sin x in order to derive some trigonometric identities. There are also rotations 180 degrees about points on the x-axis...

Practice identifying lines of symmetry on shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
