Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Individuals discover how to draw cubes on triangle-dot paper. They use cubes to build structures and draw corresponding isometric drawings on dot paper in the second lesson of the series of five. The activity also introduces the concept...

After determining the volume of various drinking glasses , class members evaluate sample responses to the same task to identify errors in reasoning.

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.  

Students observe and discuss the advantages of camouflage, then try their hands at designing a well-camouflaged fish.

Junior designers brainstorm the elements that a bedroom might have, such as a bed, television, and dresser. They identify which items are needs and which are desires. They practice measurement skills in the classroom by determining its...

Students examine problem solving techniques when working on spatial problems. They discover how models, sketches, and drawings can be used to understand on something works. They design a model of a bridge using given dimensions and...

Middle and high school students engage in enameling and apply design elements. They study the history and tradition of Cloisonne. The history of traditional Chinese Cloisonne dates back over 700 years, with the most beautiful, artistic...

Host an exciting lab in which learners burn fruit rinds to better understand hydrocarbons. A reading passage and analysis questions wrap up the lesson. 

Sixth grade young scholars: 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.

Second graders are introduced to geometry by a teacher made puppet called Geo George.

Students explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and construct...

Students listen to a read aloud of The Quiltmaker's Gift by Jeff Brumbeau finding examples of symmetry in the illustrations in the book.

Students calculate the volume of the Pantheon's columns and estimate changes in weight given different parameters.

The students are able to use a formula to calculate the volume of cuboids by measuring the length of each of the three dimensions. They also investigate the relationship between milliliters and cubic centimeters.

Seventh graders complete activities to further their understanding of area formulas. In this area lesson, 7th graders watch as the teacher uses Polystrips to model parallelograms. Students find the area of a rectangle and answer...

Young scholars study related addition and subtraction facts. For this math lesson, students use related addition and subtraction to solve problems. Young scholars use manipulatives to explore fact families.

Learners build a Lego design and then work with a partner to reproduce that design. They guide the building of the reproduction by description only and then check their work.

Young scholars explore the elements of contrast, emphasis, pattern, and color schemes by identifying how the artist manipulated tesserae in the mosaic. They create original mosaics by manipulating torn paper to depict different textures...

Fourth graders determine the value of ? by measuring the circumference and diameter of circular objects such as soup cans, Oreo cookies, etc..

Students calculate the inscribed angle of a triangle. In this geometry lesson, students identify the angle created by intersection of a triangle and a circle. They see the relationship between the arc and the angle.

Students use the secant and secant segment theorem to solve problems. In this calculus lesson, students identify where the secant line crosses on a circle. They create circles and secants using cabri software.

Students explore geometry by participating in a school measuring activity. In this perimeter lesson, students discuss the techniques and methods used in order to measure a large perimeter or geometric figure. Students utilize grid paper,...

Students create an imaginary bird. In this anatomy instructional activity, students analyze how artists represent birds historically, then determine the anatomical aspects that suit a bird to its habitat. Using this information, students...
