Geometry is more than just vocabulary. Pupils learn the basic geometric definitions and how to identify and name points, lines, and planes. Though the first lesson is packed with related vocabulary, scholars experience four postulates...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

Develop a sense of understanding. Pupils learn eight definitions dealing with types of lines and angles formed when two lines are crossed by another line. Learners use the definitions to identify the lines and pairs of angles in figures...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

What, you mean there is algebra in a Geometry class? Pupils review graphing and writing the equations of lines in slope-intercept form. The instruction follows the "I do, we do, you do" framework of a lesson. The instructor first...

Boat ramps move with waves and changes in water level. Scholars decide on the proper length for a ramp so the angle connecting both sides is appropriate. They visualize the situation and use a simulation to view the results with their...

Collaborative learners will see the geometric addition of functions by graphing the sum of two graphed curves on the same coordinate plane. This task then naturally flows into giving learners the algebraic representation of the curves...

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

Take some time to reflect on graphing. Learners count a point's distance from the line of reflection to create reflections of geometric figures. Given the rules for four basic lines of reflections, pupils determine the points to create...

Here is a tri-faceted resource that has a slide show, a quiz, and a vocabulary list that you can use to teach simple machines. Six machines are introduced: wheels and axles, planes, levers, pulleys, wedges, and screws. Slides contain...

Your Algebra learners will appreciate this fabulous, two-page printable. The first page has a list of numbers that lead to the learners writing an equation in a cloud that represents these numbers, and then filling in a table, and...

Turn the class around. Scholars define rotations of multiples of 90 degrees and create algebraic mappings for them. After an introduction to symmetry, pupils determine which letters of the alphabet have rotational and reflectional...

Here is a task that gives the graph of the solutions of a system of linear inequalities and asks learners to analyze and write the algebraic form of the systems. By turning the problem around, learners make the connections between...

Using an amusing amusement park, Sam describes how it is a coordinate plane and how to graph an ordered pair. Perfect for beginners, the animation moves on to point out a tip using the first quadrant of an empty coordinate plane.

Space explorers take a virtual trip around the sun right within your classroom! They stand in a circle facing away from the "sun" (a lamp) in the center of the room. As they move according to your instructions, they view different...

Your class will watch as one child orbits the sun as Earth, while another orbits as Mars. If the timing is right, they will see the repetitive dance between the two planets and discover how often they are opposite from each other. For...

Fourth graders discover coordinate systems.  For this mapping lesson, 4th graders create a coordinate system for theater seating.  Students observe a video based on a theater's seating map.

Fifth graders complete activities to investigate parallel and perpendicular lines. In this plane geometry instructional activity, 5th graders watch a movie about parallel and perpendicular lines. Students work in pairs to describe and...

While only briefly mentioned in most Physics books, plane mirrors and their applications offer the basics necessary for future studies. While working through an interactive, pupils demonstrate knowledge of both reflection and its forms....

Here is a lesson on coordinates that has pupils view three Cyberchase video clips illustrating the definition of "point" and "line." Along the way, learners will discuss what characters from the videos do, and where problems lie in...

This traditional textbook style unit includes vocabulary, a direct explanation section, examples, practice problems that directly line up with the explanations and examples, and a unit summary review and practice problems. Learners get...

Students investigate biology by researching wild animals. In this animal extinction lesson, students research African wild dogs and discuss the impact of the environment on their survival. Students read and analyze an article titled...

Second graders identify shapes and measurements in everyday life.  In this measurement lesson, 2nd graders locate rectangles in their classroom and use standard and nonstandard forms to measure them.  Students view a video clip...
