Seeking to derive the formula for the volume of a square pyramid, geometry learners construct six square based pyramids that, when pieced together properly, form a cube. Two short videos demonstrate the relationship...

Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build...

Identify the nets for prisms and other geometric shapes. Learners calculate the surface area of the rectangular prism then sketch the shapes of prisms and other polygons. Unfolded cereal boxes are used as a visual aid, great idea!

Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...

Students sketch the shape of three dimensional pyramids using nets. In this geometry lesson, students differentiate a pyramid from other three dimensional shape. They define the attributes of pyramids.

Pupils sketch the nets for given polygons and cylinders. For this geometry lesson, students find the measurements that correspond with prisms, cones and cylinders. they identify parts of three-dimensional shapes.

Students differentiate triangular prisms from other prisms using nets. In this geometry activity, students define the properties of a triangular prism and its symmetry. They build a triangular prism moving lines around.

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

Students identify and sketch the nets for sphere. In this geometry lesson, students differentiate between two and three dimensional shapes. They find the surface area of each sphere.

Here is a turnkey lesson that walks young statisticians through the development and uses of conditional probability. From dice games to surveys, Venn diagrams to frequency tables, the class learns how a given can effect the overall...

Pupils calculate the surface area of prisms. In this geometry lesson, students investigate the properties of prisms and analyze ways to calculate the are of a rectangular prism. They derive the formula for surface area.

Students create an image using given coordinates and evaluate how the coordinates change when a slide or rotation takes place.

Learners participate in activities the connect measurement to geometry, statistics, estimation, and the real world. They collect measurements from their elbow to the tip of their middle finger and make a box plot of the data as well as...

Students explore geometry by participating in a class card game. In this triangle lesson, students utilize playing cards with shapes on them which they group up and discard, similar to "Old Maid." Students complete a worksheet and answer...

Ready to introduce your class to the coordinate plane? This website includes a detailed lesson plan that includes two interactive games to help learners practice graphing ordered pairs. The scripted discussion is a little cheesy and a...

Learners play a game with shapes. They work in groups to identify the names and characteristics of various shapes. They give each other clues to see if others can identify the shape being described. This is a great hands on activity.

Students create nets of cylinders. In this geometry instructional activity, students calculate the surface area of cylinders and other solids. They show their understanding of three-dimensional shapes by solving problems.

Students create a geometric pattern using mandalas, polygons and symmetry. In this geometry lesson, students analyze the mathematics involved in making the mandalas, including the shapes and symmetry. Students create their own mandalas...

Students study area and quadrilaterals. In this multiplication and area instructional activity, students use Polystrip models to change rectangles to form different parallelograms. Students find the area of the models use a Geometer...

First graders participate in hands-on activities and use objects to create patterns. They observe a PowerPoint lesson plan describing matching objects and patterns. In groups, 1st graders complete geometry computer activities such as...

Learners investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

Studetns use a spreadsheet to organize data on the sides of a triangle. They use the Pythagorean Theorem and the If then spreadsheet function to decide whether the three sides determine a right triangle. Students work individual...

Students explore geometry by analyzing different shapes. In this shape identification lesson, students discuss the characteristics that make certain shapes unique and the same characteristics that cause shapes to look the same. Students...

Students calculate the volume of different polygons. In this geometry lesson, students identify the relationship between base and height. They calculate the area of each prism and cylinder.
