An Introduction To Quadrilaterals
Young geometers investigate and apply properties of quadrilaterals.  After a review and discussion of key terms, students use a computer applet to explore four-sided figures and classify them according to their attributes. The...

Word Problems Dealing with Ratio and Proportion
Mindful middle-schoolers read and solve a number of word problems. Learners copy and discuss what they believe their strategies are in solving each problem. They also write their findings and share with the rest of the class.

Perimeter and Area of Similar Figures
Students explore the relationships between similar figures. In this relationships between similar figures lesson plan, students discuss relationships between perimeter, circumference, area, surface area, and volume of similar figures...

Introductory to Area (Squares, Rectangles, and Triangles)
Students explore the concept of finding area. In this finding area lesson, students use knowledge of area of triangles to find area of squares and rectangles.  Students find area of irregular figures by breaking the figure down into...

Transformations
Students explore the concept of transformations. In this transformations lesson, students use Geometer's Sketchpad to construct cyclic and dihedral figures. Students study reflection and rotation symmetry. Students discuss vertical,...

Bones
Fifth graders observe real bones and models to learn about the structure and function of the skeletal system. In this skeletal system lesson, 5th graders manipulate objects and models of bones. They handle real bones and determine the...

Identifying Lines: Horizontal, Vertical, and Oblique
Second graders  identify horizontal, vertical, and oblique lines on a worksheet after learning them in  class.  They  demonstrate a horizontal line with their arms while saying the word and use their arms with no talking to demonstrate...

Tessellations Lesson
Fifth graders demonstrate their understanding of tessellations by watching a teacher prepared Powerpoint presentation and completing an activity.  The students work independently to identify tessellations.

An Introduction to Quadrilaterals
Students explore different types of quadrilaterals. Students define the terminology used with quadrilaterals. They create particular quadrilaterals based on specific characteristics of the quadrilaterals using an online tool.

Count the Squares and Compare
Fourth graders construct squares and rectanges in order to help them find areas and perimeters.  They gain an understanding of area and perimeter through teacher modeling and then they construct squares and rectangles.

Similar or Not?
Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.
