Students use the Pythagorean Theorem to explore sailboat design. In this Pythagorean Theorem lesson, two sides of a triangular sail are measured, and the theorem is used to calculate the third side. A worksheet, bulletin board design,...

Second graders develop an awareness of the power of their minds to work with visual images. All the activities in this unit help strengthen visualization that is an important tool or process in Geometry.

Students differentiate between parallel and perpendicular lines. For this geometry lesson, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.

Students problem solve a series of problems based on the Pythagorean Theorem. They apply the theorem to a number of scenarios.

Learners discover the centroid of a triangle based on Euclid's constructions. They explore locus of points of a median. They understand properties of the segments that form the median and areas of the smaller sections formed by the median.

Students calculate the volume and surface are of three-dimensional shapes. In this geometry lesson, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

Third graders begin learning about multiplication using arrays. In this multiplication with arrays lesson, 3rd graders interact with tiles on the overhead as they follow the teacher in making arrays. They write multiplication sentences...

Fifth graders learn and then demonstrate their knowledge of a bar and a circle graph using the classroom data. Students are given a pack of skittles candy. Students create a bar and circle graph indicating the results of the contents of...

Students calculate the speed using metric measurements. In this geometry activity, students calculate speed, distance and velocity using metric measurements. They gain inquiry and problem solving skills in this assignment.

Students classify triangles by the length of their sides. In this geometry instructional activity, students use a white board to demonstrate the angles of various triangles. Students construct an equilateral, isosceles, and a scalene...

Students calculate the surface area and volume of a sphere. For this geometry lesson, students define nets, surface areas and volume of prisms, pyramids, cylinders and cones. They use the computer to create nets and analyze shapes.

Fifth graders investigate the area of a triangle. For this geometry lesson, 5th graders practice finding the area of a triangle using the correct formula: 1/2bh.

Students review geometry unit content through a vocabulary/word game. They demonstrate understanding using geoboards to answer questions. They work in groups and it's a race to the correct answer.

Students study the sense of touch and various degrees of heat. They design a model that displays how the human hand reacts to heat using a touch sensor.

Students investigate architecture and construction by building a home from cardboard tubes.  In this housing lesson, students collaborate in groups to plan and create buildings they can fit in made from cardboard tubes, newspaper...

Students measure using tools they have made. In this algebra lesson, students measure the height and distance using non-traditional measuring methods. They apply their findings to algebra and trigonometry properties of measurements.

Learners practice measuring the height of redwood trees. On a group walk, they observe the height of various trees and identify the species. In groups, they use their geometry skills and other techniques to measure the tree and determine...

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

Ninth graders explore a variety of geometry and science concept while making an origami frog. The fold paper into the shape of a frog and conduct measurement activities including frog leaps.

Pupils explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...
