Shapes to Forms
Here is a math lesson that is really a visual arts lesson in disguise! In it, pupils utilize their knowledge of geometric shapes and forms to create a detailed version of a cylinder. The instructions on how to go about the task are very...
Curated OER
Shapes
Students identify five basic shapes. They participate in a hands-on activity in which they work with the different shapes. They name the characteristics that accompany each shape.
Curated OER
The X-33 and the X-38
Students explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.

If the Shape Fits
Geometers juggle the idea of polygons. Using a game and manipulatives, they make trapezoids and irregular polygons. They review the algorithms for finding the areas of squares and rectangles. On day one, they find the area of trapezoids,...
Curated OER
Try Tessellation
Most middle schoolers probably feel that quilting is at best an activity left to their grandmothers. This lesson uses the Zome modeling system to get them to realize how shapes in quilting are really tessellations and repeating patterns....
Curated OER
Pythagorean Theorem
Students solve problems using the Pythagorean Theorem. For this geometry lesson,students identify the right angle, hypotenuse and legs of a right triangle. They find the missing sides using the ratios of the Pythagorean theorem.
Curated OER
The Centroid : Balancing the History
Students discover the centroid of a triangle based on Euclid's constructions. They explore locus of points of a median. They understand properties of the segments that form the median and areas of the smaller sections formed by the median.
Curated OER
Math/Quilt Connection
Students explore quilting. In this math patterns lesson, students define the perimeter of a quilt border, create tessellations using geometric shapes, and detemine the area of a quilt.
Curated OER
Spark Activity: Parachute Switcheroo
Students move from one parachute to another, based on a color called out by the teacher. Students attempt to move before the teacher counts to five. Students discuss direction and moving in clockwise and counter clockwise directions.
Curated OER
Fashion Day
Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.
Curated OER
Pythagorean Triple
Learners investigate the properties of the Pythagorean Theorem. In this geometry instructional activity, students identify the missing angles and sides of a right triangle. They label the hypotenuse and legs of a right triangle correctly.
Curated OER
CSI Investigation of Congruence and Similarity
Students differentiate between similarity and congruence using polygons. In this geometry lesson, students label triangles based on their properties. They find missing sides and angles using the interior sum theorem.

The Volume Formula of a Pyramid and Cone
Our teacher told us the formula had one-third, but why? Using manipulatives, classmates try to explain the volume formula for a pyramid. After constructing a cube with six congruent pyramids, pupils use scaling principles from previous...
Teach Engineering
New Perspectives: Two-Axis Rotation
Two-axis rotations ... twice the fun as one-axis rotations! The last installment of a five-part module teaches scholars how to conduct two-axis rotations. They create isometric drawings before and after the rotations.
Curated OER
Pyramids- Slant Height and Altitude
Students calculate the height and altitude of a pyramid. In this geometry lesson, students define the parts that make up a pyramid. They use the Pythagorean Theorem to find the missing parts of a pyramid.
Curated OER
Connections: Peddling Petals
Students identify various patterns. In this patterns instructional activity, students assemble paper flowers by using patterns. Students discuss how they constructed their flower.
