Identify the nets for prisms and other geometric shapes. Learners calculate the surface area of the rectangular prism then sketch the shapes of prisms and other polygons. Unfolded cereal boxes are used as a visual aid, great idea!

Children use the length, width, and height of an object to calculate the volume of a rectangular prism. They observe how to multiply three numbers at a time, and define volume. Pupils observe as the teacher demonstrates how to determine...

Learners explore intersecting lines. In this intersecting lines lesson, students investigate shapes consisting of parallel, perpendicular, and similar lines. Learners investigate these lines in shapes around them.

Students construct tangram pieces. Then they make observations and explore patterns with the pieces.

How can you see a number in nature? Here, learners discover both Fibonacci numbers and the golden ratio by exploring a number of different resources.  Note: Some of the resources are older and may be missing some of the links, but...

Students note the similarities between decimals, fractions and percentages. They practice converting numbers between these types. They participate in an activity as well.

Pupils estimate the altitude of a rocket during several flights. They create their own altitude tracking devise. They examine and discuss their results at the end of the activity.

A hands-on activity uses the Zome modeling system, and helps young geometers either learn or review their knowledge of polygons. Students build as many different 2-dimensional polygons as possible: triangle, square, rectangle, pentagon,...

Young ratio masters calculate and cut a frame (out of poster board) to accurately create an even frame around a picture of themselves. The frame needs to be proportional to the picture with constraints determined by the instructor. 

Middle schoolers will explore frieze patterns. A frieze pattern is a mathematical concept to classify designs on two-dimensional surfaces, which are repetitive in one direction, based on the symmetries in the pattern. They will explore...

Students practice using a protractor and ruler to draw various points and lines. Using a computer, they draw the points and lines in the program and describe the differences between their drawing and the computer's drawing. They complete...

Elementary and middle schoolers engage in a lesson plan of graphing in quadrant I of the coordinate plain. They use the graph to create shapes and symbols. While using a graphing calculator, they locate the points on the coordinate...

Students research designs of traditional Samoan Siapo bark cloth and identify the fabric's features. They reproduce traditional Samoan designs on a torn brown paper bag. Afterward, they solve the division and decoration of the area of...

Young scholars explore animal characteristics by participating in an animal anatomy activity. In this animal tracks lesson, students identify the differences between specific animals and the shape of their footprints. Young scholars...

Students use computer applets to demonstrate three dimensional coordinate planes. In this coordinate planes lesson plan, students play a coordinate game and a maze game.

Learners participate in guessing their partners' hidden Lego pieces from their verbal clues. They work in partners to accomplish their goals. They are meeting a variety of math standards by completing this lesson.

Students study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.

Young scholars explore encryption. They discuss the importance of cryptography in our daily lives. Students use games and cryptography to discover transformational geometry and modulo systems. They design their own encryption puzzles...

Students use the internet to research how biometrics is being used in the real world today. They work together to research hand geometry applications. They share their findings with the class.

Students explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on students.

Middle schoolers explore angle measure as they estimate angle measure and measure and draw angles of less than 360 degrees. The lesson emphasizes the use of estimation when measuring angles.

Learners construct frieze patterns using translations and rotations. They will discuss how frieze patterns are similar to jigsaw puzzles and use Cabri Jr. to build a triangle frieze pattern using rotations, translations, and reflections.

Young scholars explore the concept of angles formed by parallel lines.They graph two parallel lines cut by a transversal, then measure the angles formed by the transversal and record the data in a table. Learners make conjectures about...

Students explore tessellations and the artwork of M.C. Escher. They view and discuss a video about M.C. Escher, create a slide template out of cardboard, and create a poster with their tessellation pattern.
