Pupils examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

Pupils explore the concept of trapezoids.  In this trapezoids instructional activity, young scholars identify legs and bases of a trapezoid.  Pupils discuss the similarities and differences between isosceles trapezoids and...

Students learn the difference between perimeter and area by watching a video and a hands on activity.

Students work with three dimensional objects. In this geometry lesson, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.

Students review the procedure for determining appropriate types of measurements for given situations and measurement conversions. They figure perimeter, area, and volume of 2 and 3 dimensional objects.

Students calculate the area of triangles using a variety of materials including computer applets.

Second graders create an ABAB pattern with their name. In this early elementary math lesson, 2nd graders first model their names in an ABAB pattern with unifix cubes. They then recreate the pattern using letter stamps on KidPix.

Second graders count by 5's to 100. In this math lesson conducted on the 100th day of school, 2nd graders use picture stamps in the KidPix program to count by 5's and get to 100.

Tenth graders investigate the Pythagorean Theorem. Then they type up a formal paragraph proof of a proof of their choice.

Students use their county's information page to gather information about their community. Using the information, they create graphs from the tables provided and interpret the data. They write a paragraph showing their interpretation of...

Young scholars use Geometers SketchPad to find the area and perimeter of several shapes. In this geometry lesson, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are...

NOT A LESSON Students

Middle schoolers distinguish between possible and impossible graphs of functions, and to learn why some graphs are impossible. They have practiced plotting functions on the Cartesian coordinate plane

Sixth graders observe the creation of a tessellation with hexagons. In groups, they work with polygons to discover what shapes can be used to create tessellations and explore the angle measurements of each shape. Using internet websites,...

Students solve several differential equations. In this calculus lesson, students test their modulus calculation by testing different weights or beam lengths. They share their findings in class.

Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Pupils, after reading the Drag Equation page from the NASA Web site, demonstrate an understanding of this equation and how drag is dependent on the variables included in the equation.

Learners, after reading the Drag Equation page from the NASA Web-based textbook, demonstrate an understanding of this equation and how drag is dependent on the variables included in the equation.

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 use FoilSim to complete the activity and investigate the factors that affect lift and how wing area and lift are related.

Students survey their local forest conducting an inventory of tree species and analyzing data of local ecosystems. They design a nature trail, map the area and make a computer generated trail guide.

Students measure water and make predictions about efficiency.

Students investigate how geometry can be used in the field of fitness and physical performance. They view a video that demonstrates how doctors and therapists mention geometry as they treat sports-related injuries.

Third graders complete a classroom game used to build understanding of two and three-dimensional shapes. Diagonals, sides, regularity, congruency, angle measurements, parallels, perpendicular, faces, and edges are a few of the vocabulary...
