Learners analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationship

Students design and construct a boat out of aluminum foil and a few other simple materials. The boats then be tested by floating them in water, then adding mass until they sink. They explore the various shapes of boat construction.

Third graders explore vocabulary associated with three dimensional figures.  In this transformations instructional activity, 3rd graders create two dimensional nets for three dimensional figures.  Students become familiar with...

Students find the volume of rectangular prisms.  In this volume lesson, students use a formula to find the volume of rectangular prisms.  They discuss the definition of volume and draw rectangular prisms.  Students...

Students define ellipses and their properties. In this calculus instructional activity, students analyze ellipses for their shape, center, major and minor axes. They create a paper ellipse to have a visual of what an ellipse really...

Tenth graders explore and define the radius and diameter of a circle. In this geometry lesson, 10th graders calculate the circumference and area of a circle using real world objects and shapes. They discuss chords and lines tangent...

Young scholars observe how bird flight and machine flight are similar. In this aerodynamics lesson, students observe how birds fly and the shapes of their wings, and investigate how observing birds helped develop the concept of machine...

Tenth graders connect the history of geometry to problem solving. In this geometry lesson plan, 10th graders investigate polygons through hands on manipulatives and solve problems relating to parallelograms and triangles. They calculate...

Students explore how to use trigonometry in the aviation field.  In this aviation lesson students complete trigonometry equations that show what planes should do to land their airplanes.

For this coordinate geometry worksheet, 4th graders read the coordinates on the grid and write the name of the shape at that location.

Fourth graders identify and describe lines, shapes, and solids using formal geometric language. They use Inspiration to create a graphic organizer and outline of polygons.

Students discuss reasons to record the location of stars. They view a picture of the night sky, and discuss constellations. Students complete a worksheet of the various shapes they see in the constellations.

Students read and plot coordinates in all four quadrants and state where a shape will be after translation. They explore the concept of translation using a a four quadrant grid of the of River Tyne running through all 4 quads. In...

In this polynominoes worksheet, students solve 9 different types of polynominoes problems. First, they identify that a polynominoe is a polygon made from squares of the same size and connected to each square. Then, students determine how...

Learners identify symmetry in road signs. For this geometry lesson, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.

A hands-on activity uses the Zome modeling system, and helps young geometers either learn or review their knowledge of polygons. Young scholars build as many different 2-dimensional polygons as possible: triangle, square, rectangle,...

What are polygons? Learners find the perimeter of various geometric figures that the teacher has drawn in chalk on the sidewalk. A worksheet to record their measurements is provided. Get your third graders outside and exploring the world...

Students explore the concept of tessellations. In this tessellations instructional activity, students use an applet to construct tessellations. Students use regular polygons to construct tessellations. Students find patterns and symmetry...

Geometry in life-sized dimensions! Using enlarged graph paper, pupils perform a series of transformations. By recording the initial and final placement of the images, they are able to analyze the patterns in the coordinates during a...

Do not let friction drag you down! The 11th segment in a series of 22 focuses on the fourth force acting upon an airplane—drag. Pupils learn about the effects and causes of drag.

While it may seem incredibly obvious to the geometry student that congruent sides make congruent triangles, the proving of this by definition actually takes a bit of work. This exercise steps the class through this kind of proof by...

Up, up, and away! Take your classes on a physics adventure. Learners explore the concepts important for flight. They experiment with the Bernoulli Principle while learning the forces that act on airplanes in flight.

How similar do figures have to be to be similar figures? Individuals learn to identify similar figures by verifying that angles are congruent and sides are proportional. Additionally, they match the corresponding parts of similar figures.

How important is aviation? Using the background information, teachers provide the class with a brief history of aviation. The class discusses how airplanes are important to the area of transportation in the 17th installment of a...
