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 design a cafeteria floor plan. In this area and perimeter lesson, groups create an efficient lunchroom layout on poster board by using geometric shapes and formulas as the basis for their designs. In the accompanying writing...

Learners infer the galaxy shape.  In this structure of the galaxy lesson plan students observe the distribution of objects in the sky and answer questions.

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,...

Students differentiate between inscribed quadrilaterals and parallelograms. In 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 inscribed...

Students explore the concepts of length, perimeter and area. Students develop an understanding of length, perimeter, and area. Students calculate the area and perimeter of random shapes and calculate the area and perimeter of a triangle...

Students examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Students experiment with the area and perimeter of polygons. Students analyze...

Learners examine the attribute of equilateral triangles. In this equilateral triangle lesson, students examine a number of paper triangles to determine how they are classified. They determine how triangles are depicted in Navajo rugs.

Second graders explore the features of triangles and quadrilaterals. In this lesson on triangles and quadrilaterals, 2nd graders rotate with their group to five different activities all exploring a different aspect of geometry.

Students use shapes and manipulatives to demonstrate patterns. In this patterns lesson plan, students also break up patterns to identify a pattern unit.

Learners use current knowledge to predict the meaning of line of symmetry. They explore symmetry using mirrors.

Students learn the difference between perimeter and area by watching a video and a hands on activity.

Learners review types of polygons and list several examples of each. They assume the role of a landscape artist interviewing for a job. They create sketches of their plans for six polygonal gardens and write an expository paragraph...

Pupils explore the idea that primitive virtual 3D objects can be reshaped to infinitely original combinations using additive and subtractive methods. They create 3-D objects with a computer which necessitates a cooperation of right-brain...
