Young scholars make and fly a sled kite out of plastic garbage bags, dowel rods, and more. In this kite lesson plan, students plan the kite to have symmetry and make adjustments as they test it.

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

Students differentiate between inscribed quadrilaterals and parallelograms. For this geometry lesson, students identify the shaped of the polygons when it is inscribed inside of a circle. They calculate the missing angles of the...

Students explore the relationship of angles as it relates to 2 and 3-D shapes. In this geometry lesson, students differentiate between acute, obtuse, right, alternate interior, exterior and adjacent angles. They manipulate a math...

Students identify the secant segment of a circle. In this geometry lesson plan, students investigate secant lines formed outside the circle. They use Cabri software to create drawings and explore circles and secants.

Fourth graders examine and discuss the purposes and traditions of African ceremonial masks. They design and create African ceremonial masks using various materials.

Students explore tessellations as well as various types of polygon. Students examine tessellating patterns in the world around them. Students examine tessellations by creating their own tessellations and completing the included worksheet.

Students calculate the measurements of the inscribed angles of a triangle. In this geometry lesson, students relate the hypotenuse of a right triangle and the diameter of a circle to each other. They calculate the diameter of a circle as...

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.

Students identify how to classify living things. They classify various concepts including family members, kinds of clothing, numbers, shapes, and vocabulary words. They discuss how to classify various concepts and classify pictures of...

Students study the history of kites and their fundamental properties.  In this kites lesson students divide into teams and build and fly kites. 

Students work with a set of objects to set up both quantitative and qualitative classification systems. As a group, students follow an example to design and complete two classification systems using a set of objects provided. ...

Students study relationships between angles, side lengths, perimeters, areas and volumes of similar objects. For this lesson students also create and critique inductive and deductive arguments concerning congruency, similarity and the...

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

Students identify missing sides and angles. In this geometry lesson, students use triangular theorems to identify the missing sides. They use the Pythagorean Theorem to find the different ratios of each side.

Third graders participate in a game in order to review geometric concepts.

Students explore the concept of origami. In this origami lesson, students construct picture frames out of paper. Students find the midpoint of the paper and determine the fractional area of the paper as it is folded.

Students complete readings on kite making and kite flying. They analyze how the parts of a system interconnect and influence each other. Students identifies and uses color and form in a 3D artwork.

Students practice creating art by imitating the camouflage of fish. For this animal characteristic lesson, students identify certain fish and their ability to change colors in order to survive in the wild. Students utilize coloring...

Students are introduced to the topic of area. In groups, they share various techniques to help them identify different shapes and work together to calculate the area. They use this same knowledge to determine the area of animal tracks...

Students identify the different types of fractals. For this geometry lesson, students use math to analyze different biological phenomena. They collect data from the experiments and construct graphs.

Students in a teacher education program enhance their awareness of patterns. They discover how to support their students in developing this skill in mathematical terms. They role play the role of a K-2 student and collect images from...

Fifth graders participate in a review game of geometry topics. In this geometry instructional activity, 5th graders use the "Eggspert" interactive classroom game system to review the geometry skills taught that week. Students work in...

Students create and color a one-patch quilt design based upon a regular hexagon. They examine quilts and photos of quilt designs, read a handout, and complete their quilt design on a worksheet.
