Students explore the concept of similarity and congruence. For this similarity and congruence lesson, students identify and verify whether or not two figures are similar, congruent, or neither. Students use postulates and theorems such...

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 study the Renaissance and the important art from the period. In this Renaissance lesson, students discuss the black plague and religion during the Renaissance. Students read the Renaissance worksheet and learn vocabulary words...

Learners explore circles.  In this geometry lesson, students explore the relationship between the circumference of a circle, the distance a ball travels, and the number of rotations the ball must make in order to travel a certain...

Students study fractions. In this art lesson, students fold paper, use origami, making new shapes and discuss the area of the shapes created.

Pupils investigate circles and compound locus. For this geometry lesson, students identify the distance from a point to a line. They use Cabri software to create lines and circles.

Students differentiate between ellipse and hyperbola. For this algebra lesson, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.

Students find missing angles and sides of triangles. In this geometry lesson, students create intersecting lines to measure angles. They use Cabri Software to create virtual angles.

Students investigate two and three dimensional shapes. For this geometry lesson, students write equations of circles and graph them correctly. They create pictures using circles.

Students identify the pattern in a problem. In this geometry lesson, students make predictions, collect and analyze data. They apply the idea of scales and measurements to the real world.

Learners differentiate between parallel and perpendicular lines. In this geometry lesson, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.

Middle schoolers classify prisms according to their attributes. For this classifying prisms lesson, students explore different prisms. Middle schoolers generate observations of the attributes and classify the prism correctly.

Students study pyramids. In this prisms lesson plan, students explore the attributes of pyramids. Students will explore the lateral surface area of pyramids and be able to distinguish pyramids from other space shapes.

Students 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.

Students investigate triangles. In this shapes geometry lesson, students define and state the attributes for equilateral, scalene, and isosceles triangles. Students locate the prefix "tri" in a variety of words and make connections with...

Students calculate the volume and surface are of three-dimensional shapes. In this geometry activity, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

Students find number patterns in the generation of several different types of fractals.

Students explore the concept of fractal patterns. In this fractal pattern lesson, students use an applet about the Hilbert Curve to answer questions about rectangles and other polygons. Students derive the fractal pattern when dividing...

Students explore the concept of irregular fractals. In this irregular fractals lesson, students discuss how to find fractal dimensions through teacher led discussion. Students calculate fractal dimensions of various fractals.

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

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.

Students explore the Mandelbrot Set. They are introduced to the concept of a complex number and function in order to motivate the discussion of Julia and Mandelbrot sets. Students investigate fractals and how they are built.

Students stud angles, and then play the "What's Your Angle?" game. They complete at least 10 computer generated problems from the Angles Applet.
