This lesson plan reviews transformations in the coordinate plane while mimicking real-world planning skills. It gives an assessment and ideas for remediation, extention as well as ways to manage behavior problems and reluctant learners.

Students make connections between the coordinate grid and Geometry by finding the distance of line segments using the coordinate plane. This lesson includes a detailed lesson plan, slides containing notes and problems, and a...

In a coordinate proof, geometric statements using algebra and the coordinate plane.

Explains how simple polygons translate into matrices and how to use 2x2 matrices to represent transformations in a plane. Includes video demonstrating an example where a vector must be rotated 90 degrees using matrices. [4:18]

First graders begin to learn about plane shapes in Kindergarten. This lesson will serve as review of plane shapes' characteristics and extend into practice in categorizing shapes by defining attributes.

Provides examples and a video lesson that introduce fundamental statements of geometry.

A transformation is a function that takes points in the plane as inputs and gives other points as outputs. You can think of a transformation as a rule that tells you how to create new points from old points.

Learn about planes with this useful reference guide. Provides a detailed definition and examples that enhance further explanation. Includes links to related topics.

This site from Whatis.com provides a great definition of cartesian coordinates. The definition is medium-sized in length and has links to additional information as well.

Students are able to manipulate a parallelogram on a coordinate grid to explore properties of a parallelogram and then calculate the distance of the sides, altitude, and area. The resource also includes links to further explain important...

[Free Registration/Login may be required to access all resource tools.] Transformations move and modify geometric shapes. There are several types of transformations that all transform figures in different ways. These transformations can...

[Free Registration/Login may be required to access all resource tools.] This study guide reviews the terminology for circles (tangent, arcs, central angles) and the equation for a circle.

Explore connections between a 2-dimensional net and a 3-dimensional box. Later in this section, use equations with variables to solve real world problems that use 2 and 3-dimensional objects.

In order to better understand why your world is three dimensional, consider zero, one and two dimensions.

Learn about the tangent definition in geometry, tangent geometry, tangent to a circle, tangent line equation. Check-out the solved examples for better understanding and try your hand at the tangent line calculator or solving a few...

A rigid motion of the plane is a map of the plane to itself which preserves distances between points. The purpose of this task is to use fixed points as a tool for studying and classifying rigid motions of the plane, i.e., translations,...

This question examines the algebraic equations for three different spheres. The intersections of each pair of spheres are then studied, both using the equations and thinking about the geometry of the spheres. Aligns with A-CED.A.2 and...

I love blending art and math. I want my students to develop a depth of knowledge for 2D plane shapes and distinguish polygon from non-polygon shapes.

Presents biographical information about Rene Descartes (1596-1650), his career, personal life, written works, and his legacy. Covers contributions to philosophy, mathematics, and science.

Use this calculator to calculate the distance between 2 points by entering 2 sets of coordinates in the 3-dimensional Cartesian coordinate system, (X1, Y1, Z1) and (X2, Y2, Z2), to get the distance formula calculation for the 2 points...

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...

Use triangles and worksheets to guide the learning of triangles to the discovery of the Pythagorean Theorem.

This task challenges a student to use knowledge of geometrical attributes to identify and describe shapes.

Use this site to practice identifying shapes, colors, and animals with these interactive games.
