Visualizing Solids of Revolution - Washers
Students solve the area of a cross section. In this calculus instructional activity, students solve areas rotated and bounded by two functions. They solve using the washer method.
NASA
The NBL Pool
That is a lot of water. Class groups explore the size of the NASA's Neutral Buoyancy Pool and calculate the volume of water needed to fill it. They then compare that volume to the amount of water needed to fill a pool the size of a...

Study Buddies - Bar Graphs
In this data collection worksheet, students work with a partner to make 3 small bar graphs after finding the proper number of circles on the first page. They look at a page of a variety of shapes and separate the circles into black,...
Curated OER
Area
Students use different shapes that represent tangrams to determine the area of a space. In this area lesson plan, students trace shapes and have their partners determine the area of that shape.
Curated OER
Surface Area of Rectagular Prisms
Sixth graders investigate the area of polygons. In this geometry lesson, 6th graders calculate area of prisms using geometric formulas. They work with prisms and other rectangular shapes.
Curated OER
Effect on Surface Area and Volume
Students identify the effect the change of dimensions causes for the volume and surface area. In this geometry lesson, students compare perimeter, area and volume as they play around with the dimensions of the polygons. They discuss...
Curated OER
That's So Square
Second graders are introduced to circles, triangles and parallelograms. As a class, they create the shape with their bodies and are shown the shapes in their actual size. To end the instructional activity, they sketch each shape and...
Curated OER
Chopping Cubes
Middle schoolers work in small groups to make various geometric solids with Play-Doh. They use fishing line to make cuts and observe the shapes of the cross-sections. Pupils complete an assessment in which they answer questions such as:...

Separating Soup Mix
Students use screens of three sizes to separate a mixture of five solid materials. They plan and conduct simple investigations using appropriate tools, measures, and safety rules and record and report observations, explanations, and...
Curated OER
Investigation-On the Surface
Learners compute the surface area of 3 geometric solids to determine the shape of package that would require the least amount of paper to wrap. In this geometry lesson, students work on a two-question assessment embedded in the plan. The...
Curated OER
Geometry Slideshow
Sixth graders create slideshows of geometric terms. They use images taken with digital cameras or scanned from magazines.
Curated OER
Foil Fun
Second graders be having hands-on experiences with three-dimensional solid shapes. They investigate the features of solid shapes and examine the names for them. They are introduced to making nets for 3D shapes.
Curated OER
Year Book Page Special Shape Collage
Students design a collage of pictures for a yearbook that make a shape. They determine the area of the shape and the price of putting the collage in the yearbook.
Curated OER
Opening A Cube
Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...
Curated OER
Finding Volume
Sixth graders develop a rule for finding the volume of rectangular solids using colored cubes. They investigate the properties of solid figures and find the volume of an object by counting units. Students fill spaces with standard-sized...
Curated OER
Volume of Spheres
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.
Curated OER
3-D Figures Part 2
Young scholars work with three dimensional objects. In this geometry instructional activity, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.
Curated OER
Color Me Square
Second graders identify and describe basic geometric solids. Working as a class, 2nd graders describe geometric solids using the proper vocabulary and counting faces, bases, corners, and edges. In pairs, students use a computer drawing...
