Cones, Cylinders, Spheres
Students classify polygons by name and shape. In this geometry activity, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.
Curated OER
A Sphere and Its Net
Students identify and sketch the nets for sphere. In this geometry instructional activity, students differentiate between two and three dimensional shapes. They find the surface area of each sphere.
Curated OER
Using Concept Maps to Design 3D Spheres
Young scholars create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.
Curated OER
Surface Area
Students calculate the surface area of cubes, solids and cylinders. In this geometry lesson, students define the surface area formulas for different prisms. They calculate the surface area with 100%, and 80% accuracy.

Introduction to Trigonometric Functions
Scholars first learn the definitions of the sine ratio, the cosine ratio, and the tangent ratio. After mastering these definitions, they use the new information to solve triangles.
Curated OER
Finding the Area Under A Curve with Random Probability
Students explore the concept of area under a curve. In this area under a curve lesson, students find the area under a curve using the Monte Carlo method using random points and probability. Students calculate the area under the same...

Lawn Mowing
This is how long we mow the lawn together. The assessment requires the class to work with combining ratios and proportional reasoning. Pupils determine the unit rate of mowers and calculate the time required to mow a lawn if they work...
Noyce Foundation
Parallelogram
Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Which is Bigger?
To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.
Curated OER
Poly-Mania
This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...
Curated OER
Bubble and Boyle
Middle-schoolers still enjoy playing with bubbles! For this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more!
Curated OER
The Circle's Measure
Pupils explore circumference and diameter. In this math lesson, students apply their knowledge of circumference and diameter to solve mathematical riddles. Pupils apply this knowledge to find circumference and diameter of various objects.
Curated OER
Analyzing 3-D Shapes and 2-D Representations
Students can analyze 3-D objects better with actual physical models and by also drawing 2-D representations of them.
Curated OER
Rep Tiles
Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...
Curated OER
Creating a "Concrete" Spreadsheet
Students create a spreadsheet that calculate the amount of concrete needed to pour various concrete forms.
Curated OER
Family Activity-- Finding Areas of Triangles
In this math worksheet, students work at home with a family member to identify triangles and find the areas. Students find 3 triangles in tile patterns, wallpaper, paintings or anywhere in the home and answer 6 questions.
Curated OER
Houses
Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...
