Tenth graders investigate geometric construction.  In this geometry lesson, 10th graders explore the procedure for copying an angle and a segment.  The lesson emphasizes the difference between a sketch, a drawing, and a...

Students explore the concept of transformations. In this transformations lesson, students use Geometer's Sketchpad to construct cyclic and dihedral figures. Students study reflection and rotation symmetry. Students discuss vertical,...

Students explain how sunlight is converted to electricity. In this series of physics lesson, students study how varying the characteristics of the light source affect photovoltaic cells. They research their different uses in other...

Students view a video to gather information about our solar system. They create models of the planets to scale and place them in scale relative to their distances from the sun. They also visit a planetarium or use the internet to gather...

High schoolers study the history of kites and their fundamental properties.  For this kites lesson students divide into teams and build and fly kites. 

Students examine nautical navigation and discover the differences between nautical charts and other types of maps or charts. Students practice setting a course, taking a bearing, and dead reckoning. This gives students an example of...

Students draw and measure angles. In this angle measurement lesson, the teacher demonstrates how to form and measure angles while explaining the parts of an angle, then students practice.

Young scholars classify and measure angles.  For this angular lesson, students measure, contruct, and classify angles.  They identify angles as acute, right, obtuse, and straight. 

Students discover the difference between triangles. For this triangle lesson plan, students discuss the different types of triangles, then draw the three different types of triangles. The teacher will draw, or model, how to draw the...

Learners create Optical Art, art that seems to move when you look at it, in this Art lesson for the High School classroom. Included with the lesson is a list of recommended materials and suggested resource books for lesson implementation.

Students draw triangles. In this shapes lesson, students discuss what they already know about triangles, what they are and what they are made up of. Students discuss the types of triangles and practice drawing each type.

Tenth graders identify angles formed by parallel lines and a transversal. Using meter sticks and bolts, they perform hands-on activities to demonstrate the properties of parallel lines and congruent angles. They color code diagrams to...

Learners examine how light waves travel. In this properties of light lesson, students observe how light travels in water, how light is reflected and refracted, and how light is pure energy.

Students use problem solving skills to create various models of tricubes, tetracubes, and pentacubes. They classify the cubes into various groupings and identify them as mirror images, regular arrangements, and irregular arrangements....

Students define and identify shapes by name. In this geometry lesson, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.

Students investigate lever systems in the human body and compare arm anatomy to model.  In this human levers lesson students graph and analyze their results.

Seventh graders study ratios, scale and distances according to a three dimensional model.  In this exploratory lesson plan students create their own constellation and prepare an oral presentation that describes their model. 

Students differentiate between parallel and perpendicular lines. In this geometry lesson, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.

Students investigate special segments in triangles. In this geometry activity, students graph, compare, estimate and predict findings based on their data. They differentiate between similarity and congruence of triangles.

Students discover and discuss relationships and functions between varying dependent variables and how they affect the period of the pendulum. They use graphing calculator to express the data collected in a graph, to analyze the graph,...

Students explore properties of tangent lines.  In this properties of tangent lines instructional activity, students discuss the perpendicular relationship between a tangent line on a circle and the circle's radius.  Students...

Students examine parallax and angular measurements.  In this investigative lesson students calculate distances of objects and map their results.

Students identify similar triangles.  For this proportional segments lesson, students identify corresponding sides, set up ratios, and find the length of the missing side of a triangle.  They use the parallel/proportionality...

In this interactive lesson, learners review attributes of equilateral polygons. They are introduced to the concept of a tessellation. Using protractors and pre-cut shapes, students arrange a variety of tiles to create tessellations. They...
