Students solve and verify the solution for unknown measures. In this geometry lesson plan, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.

Students create a bridge using engineering and geometric concepts. In this geometry lesson plan, students identify the missing measures of polygons sides and angles. They work together to solve real life situation using problem...

High schoolers identify the volume of cones and pyramids. In this geometry lesson, students derive the formula for cones and pyramids. They calculate the volume of cones and other three dimensional shapes.

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

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

Students explore hispanic ficticious characters and compare them to the anglo culture.

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...

Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...

Students discuss Newton's laws of motion. The conduct motion experiments by building "Newton Rocket Cars" from assorted materials. They propel the cars with rubber bands and wooden blocks and record the distance traveled on data sheets.

Students compare the ancient Greek method of schooling and writing to contemporary methods and learn the Greek alphabet on wax tablets.

Students design and build original mobiles and consider how the forces of gravity and convection air currents affect the finished piece. They explore how an understanding of balancing forces is important in both art and engineering design.

Students explore the human body by conducting an exercise in class. In this human anatomy instructional activity, students view a diagram of the human body and identify the specific bones and joints that allow us to perform specific...

Learners observe the cracks in school walls and pavements. In this geometry lesson, students explore the factors to be considered before building a structure. They complete a graphing and calculation worksheet after the lesson.

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.

Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Students practice reading a map. In this mapping instructional activity, students illustrate a map and compare and contrast the counties based on their population. Students also explore what a census is and read census data on a map. A...

Students learn more about the census. In this mapping sub-districts lesson plan, students visualize census data on a map, use a map key to read a population map, and better understand the concept of population density.

Second graders use empty pizza boxes and pattern blocks to create a Save and Rave Box, which is a 3-D portfolio.

Students explore the names and qualities about members in the group. They each say their name and something about themselves. Students gather around in a circle. They listen to the teacher as he or she says the name of someone and throws...

Third graders spell words and define homophone.  In this making words lesson, 3rd graders decipher words from letter strips in an effort to identify the "secret word". Students use a set of letters to spell different words. 

Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.

Young scholars create and give oral proposals for the construction of a gazebo using a blueprint created with Geometer's Sketchpad. They then build a gazebo model using the blueprints created and provide evidence why it should be...

Tenth graders investigate the volume of a cylinder.  In this geometry lesson, 10th graders create three-dimensional cylinders and use a ruler to determine the dimensions.  The lesson progresses to the use of the formula to find...
