Mathematicians analyze the relationships between surface area and volume. They conduct Internet research, conduct various experiments, record the data in a spreadsheet, and graph the results and compare the rate of increase of surface...

Looking for a fun and creative way to celebrate Pi Day? Then this is the resource for you. From a scavenger hunt and trivia contest to PowerPoint presentations and skills practice worksheets, this collection of materials is a...

High schoolers identify the properties of a sphere. In this geometry lesson, students calculate the surface area of spheres using the formula derived by nets. They identify the radius and diameter of the sphere.

Take a shot using a lesson on volume! Young learners watch a video showing a trashcan filling with paper balls. The task is to calculate the number of paper balls that will fit in the can. Pupils use volume calculations to make a...

Students find the volume of spheres. In this geometry lesson, students measure and derive the formula for each shape and solid. They use the correct terminology and units when solving these problems.

Your classroom will overflow with learning as they analyze the volume in a pot of meatballs. Young mathematicians predict the number of meatballs that will make a pot of sauce overflow. They incorporate both the volume of cylinders and...

Young scholars 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...

Students observe the pattern of the inside of a mushroom and write down what they see. In this mushroom lesson plan, students cut a mushroom at the top and draw what they see in the spore of the mushroom.

Students investigate spheres through sketches. For this geometry lesson, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.

Students classify polygons by name and shape. In this geometry instructional activity, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.

Learners find the surface area of cones. In this geometry lesson, students calculate the dimensions of each three-dimensional shape and use the correct formula to solve the problem. They relate concepts of cones to the real world.

Third graders experiment to gain understanding of the shape and rotation of the Earth. In this Sun and Moon science lesson, 3rd graders understand that the Earth rotates on its axis and how that explains the appearance of the moon and sun.

Students identify different parts and properties of circles. In this geometry lesson, students identify the radius, diameter, semicircle and inscribed angle of a circle. They identify the tangent lines to a circle.

Tenth graders define the formula for cylinders and use it to solve real world problems. In this geometry activity, pupils differentiate between area, perimeters, 2D shapes, 3D shapes, and volume of prisms, cylinders and spheres. They...

Students estimate how many drops of water can fit onto the surface of a penny and then test their hypothesis to find out. They also experiment with bubbles.

Students analyze the amount of space required to pack round objects. In this geometry lesson, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to molecules being...

Tenth graders calculate the area and the volumes of polygons. For this geometry lesson, 10th graders review the formulas used to solve for the area and volume and explain to the class how they arrived at their answer. They search online...

Eighth graders use concrete and graphic models to derive formulas for finding perimeter, area, surface area, circumference, and volume of two- and three-dimensional shapes. This lesson is a fun way to practice measurement and circle and...

Students develop their globe skills. In this geography skills lesson plan, students use a globe and a softball to replicate distance between the earth and its moon.
