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

Sixth graders draw parallel and intersecting lines to observe and examine the characteristics of alternate interior angles, vertical angles, corresponding angles, and supplementary angles. Through observation, they discover the...

Fifth graders create polygons requested by their teacher. In this polygons lesson, 5th graders watch a video and listen to a song about polygons. Then, students take turns labeling various polygons and practice making polygons.

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 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 construct a bridge that can hold 100 pennies. In this math instructional activity, students evaluate the strength of their bridges. They predict how much weight a bridge can hold based on its design.

Pupils sort Lego Duplo pieces after determining the attributes to classify them by. They work in pairs to sort a group of Duplo pieces and explain their process to others.

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.

Students view examples of man-made structures and create a building that matches the style. Using the internet, they research the style of Frank Lloyd Wright and create plans for creating their own community. They use a painting of...

Fourth graders read Mary's problem and make sure that they examine it. After some discussion, let the class work on the problem in their groups. They then take turns in putting a picture of their arrangement on the board.

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson plan, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Students practice plotting functions on the Cartesian coordinate plane while participating in a discussion about the Possible Or Not worksheet/activity. Students also use the Impossible Graphs worksheet to practice reading a graph,...

Fifth graders work with polygons.

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Learners examine tessellations and their geometric properties. The lesson and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.

Pupils explore the pattern of the unit cell. In this science lesson, students color the unit cells on a worksheet and create a pattern using unit cells.

High schoolers explore the concept of translations. For this translations lesson, students discuss similarities and differences between images and pre-images. High schoolers apply translations to coordinates of figures. Students use...

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.

Students examine functions and function notation. They use computer activities to discover how to graph functions, and conduct a vertical line test. Students describe spatial relationships using coordinate geometry.

Fifth graders duplicate patterns, guess pattern results and identify the symmetries created. They are given an instructional handout, 5th graders replicate the patterns demonstrated by folding the paper and punching the appropriate...

Eighth graders use a meter stick that is placed on a horizontal surface and an object is moved along it so that the shadow length can be measured at different distances from the light source. They solve real-world problems involving...

Use dance to help learners conceptualize line segments, rays, lines, and planes. They choreograph dances that show dimensional space. Dancers start by pondering space, point, and lines as the teacher draws them in the air. Each...

Students are introduced to lines, rays, line segments and planes. They explore the differences between lines, rays, line segments and planes. Students pracice graphing lines, rays, line segments and planes.

Explore lines tangent to a circle. For this math lesson, young scholars manipulate circles and lines on a TI calculator. They draw a circle  and analyze perpendicular lines intersecting the circle in only one place. This activity...
