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 instructional activity includes a detailed lesson plan, slides containing notes and problems,...

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.

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...

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.

Rather than dividing a circle into some number of segments (like 360 degrees), mathematicians often prefer to measure angles using the circumference of a unit circle - a circle with radius 1. This way of measuring angles is called...

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 task challenges a student to demonstrate understanding of the concept of two dimensional shapes and their properties.

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.

Create regular and irregular polygons and determine the angles and side lengths with this interactive exercise. Use Safari or Chrome browser.

An interactive game to find number of edges, surfaces and vertices of different geometric shapes.

This inquiry lesson explores the definitions of quadrilaterals and the properties of the diagonals of quadrilaterals to classify quadrilaterals. Students will work cooperatively to justify conclusions. This lesson plan was created by...

This lesson allows learners to discover the number Pi. By measuring real life objects, students will get to see where the number Pi comes from as well as how the circumference formula is derived.This lesson plan was created as a result...
