Fifth graders listen to "Grandfather Tang's Story" and use tangram pieces to create animals described by the main character.

Pupils discover how to recognize tangents and how to use their properties. They investigate and use the properties of angles, arcs, chords, tangents, and secants. Students use two tangents and the properties of similar triangles to...

Pupils use their understanding of 3D on 2D to make a representation of a 4D form on paper.

Real-life math is really great! In groups, learners measure objects in the classroom. After comparing measurements, they determine a scale and create a blueprint of the classroom. They discuss the purpose of using scale drawings in...

Youngsters recognize and identify shapes. They draw, and use modeling clay to make shapes. They also identify shapes in their environment and in the Navajo culture, then compare the shapes and sort them into groups. This is the...

Learners study acute triangles. They measure angles using a protractor, then classify the triangles as either right, obtuse, or acute. Everyone creates a design for a Navajo rug using only acute triangles.

This engineering activity gets youngsters working together to design and construct a bridge. Each bridge is tested in front of the class to discover how much weight it can hold before showing any change in form. The lesson plan does not...

Students 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.

When you see a flower or a tree in nature do you see the math? This web resource contains many ideas for using fractals in a math class including Sierpinski’s triangle, Koch's Snowflake, and the Jurassic Park Fractal. Additionally, it...

Most young mathematicians are aware that the planets don’t orbit the sun in a circle but rather as an ellipse, but have never studied this interesting feature. This resource looks at the planetary orbits in more detail and helps learners...

Ask elementary students to explore shapes in everyday objects. They will discuss the elements of design and describe the shapes they see in visual images. Students will then design and "build" a new 3D shape. Finally they will show and...

Pupils study the topic of codes in Computer Science. They research it history, divisions in the field and its applications. The lesson also includes a brief overview of the information technology theory.

Students 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. Students utilize a...

All your students have likely played the age-old game "I Spy," and now you can play it in the classroom! A leader (could be you to start) chooses something in the room with a familiar geometric shape. The class begins asking yes or no...

Did you know that a soccer ball is very similar to a truncated icosahedron? Both have 32 faces, but while a truncated icosahedron is made up solely of flat hexagons, a traditional soccer ball has 12 pentagons and 20 hexagons, each curved...

Open up your pupils' eyes and minds on dilations. Scholars perform dilations on a trapezoid on the coordinate plane. They compare the image to the preimage and develop generalizations about dilations.

Young scholars study the architectural designs of different popular sites. In this math lesson, students draw a grid diagram. They explain what geodesic algorithms are used for.

Students use Cartesian coordinates or degrees of latitude and longitude to locate important locations within their specific countries. They Use a grid to apply the concept of latitude and longitude, or positive and negative Cartesian...

Students observe geometric relationships in buildings and structures. They reason why structures are constructed in a specific way by applying geometric concepts. They construct a shelter using their geometric knowledge.

Students gain an appreciation of the polygons and polyhedrons around them that make their world one of order and strength. They build polygons and polyhedrons, and then construct airplanes out of polygons.

Students explore similar objects. They participate in a series of hands-on, multimedia and online activities to examine how the edge length affects the angle measures, perimeters and areas of similar regular polygons. Students find the...

Young scholars create an atomic model using a computer program. For this technology lesson, students identify the difference between radius and diameter. They create circular patterns and spheres based on certain specifications.

Fourth graders participate in a variety of activities dealing with animal characteristics and classifications in this multi-task lesson plan. They use graphic organizers, make booklets, and make models.

Students familiarize themselves with the three most common geometric shapes: circles, triangles and parallelograms. They sketch, sort, and name the shapes.
