Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

Students, after reading the explanation given below, use FoilSim to determine the weight of the aircraft that can be lifted by a pair of wings of each type. They also design a unique platform of a wing to lift a plane weighing 11500 pounds.

Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

Solve story problems using fractions or decimals. Then, determine the reasonableness of answers using estimation.The detailed lesson plan includes essential questions, vocabulary, a materials list, and links to related units.

Pupils practice multiplying and dividing whole numbers by fractions. They study the multiplicative identity property that states that the product of any number and 1 is that number. They multiply whole numbers by fractions close to 1 and...

Students explore the relationship between geometry and ancient American art. They see how to recognize geometric properties in specific works and explain how these properties contribute to their meaning and artistic merit.

Fifth graders are introduced to Newton's First Law of Motion. In groups, they describe the differences between balanced and unbalanced forces. They participate in experiments that demonstrate how equal and opposite forces act upon...

Just exactly where does the name conic come from? This brief hands-on exploration explains it all. Have your class cut cones to create their own conics, then assess their understanding with a few identification problems. Consider making...

In this measurement lesson, learners examine the Pythagorean Theorem, perimeter, and areas of right triangles. They record their measurements and research their findings on a grid.

Students complete activities to learn about the common land features in Alaska. For this land study lesson, students study an overhead for permafrost features. Students define ice wedge polygons, thermokarst, and pingos. Students also...

Grab your class and get them graphing polygons on a coordinate plane! They investigate the four quadrants, discover the x and y axis, and correctly plot ordered pairs. To show their comprehension, each child creates a coordinate picture...

Fourth graders explore triangles. For this math lesson, 4th graders discuss the different types of triangles. Students create triangles using wiki sticks. Students complete an online matching game.

Students develop definition for parabola, explain relationship between properties of the graph of a parabola and its equation, explain how the equation of a parabola can be written in different forms, and solve problems that relate the...

Students develop a definition of parabola and explain the relationship between the properties of the graph of a parabola and its equation. They explain how the equation of a parabola can be written in different forms and solve problems...

Students interpret information and results in context while using words and symbols to generalize patterns. They use symmetry and angle properties of polygons to solve practical problems and identifying invariant properties under...

Students complete a two-week unit involving design and construction concepts. They watch a PowerPoint presentation about geometric shapes, draw the fourteen shapes incorporated in bridge construction, and in small groups design, build,...

Learners 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.

Learners investigate octagons using words and shapes. In this geometry lesson, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.

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

Students explore the different forms that water can take and conduct simple experiments to demonstrate some of its properties in each state. They watch a short video that illustrates some of these concepts.

Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

Tenth graders study graphing exponential functions. In this transformations instructional activity, 10th graders apply inquiry to determine how changes to a parent function affect its graph. Students analyze transformed graphs and...

Students define ellipses and their properties. For this calculus lesson, 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 looks like in 3D.

Students complete a table of values and plot points, as well as construct a graph on a coordinate grid. They construct two graphs on the same coordinate system, and identify the point of intersection. Students represent and record...
