Parallel lines seem so right for each other. It's too bad they'll never, ever meet. Learners use tracing paper to discover relationships among angles formed by two parallel lines cut by a transversal. They apply this information to find...

Learners make three dimensional shapes with nets. For this nets lesson, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use the...

Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

Hands-on investigation of Riemann sums becomes possible without intensive arithmetic gymnastics with this interactive lesson plan. Learners manipulate online graphing tools to develop and test theories about right, left, and...

Young scholars learn how to identify cell addresses, format cell contents, add pop-up comments to a cell, and also apply conditional formatting. They use clues and words to make a geometry crossword puzzle pertaining to geometrical shapes.

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

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!

Making a clear connection to algebra concepts helps learners understand the definition of a derivative. The instructional activity begins with looking at limits of simple linear and rational functions, and leads to the...

An outstanding activity on teaching the basic shapes and polygon names to young geometers is here for you. In it, learners investigate the role of basic polygons in the strength of structures. They use geoboards, rubber bands, streamed...

If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

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...

Young scholars examine a chart that lists the main characteristics of polygons and 3 dimensional figures. They make examples of the polygons and figures using pretzels and gum drops showing how the gum drops are vertices and the pretzels...

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.

Students sketch the nets for given polygons and cylinders. In 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 instructional 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.

The key to understanding is making connections. Scholars explore angle dilations using properties of parallel lines. At completion, pupils prove that angles of a dilation preserve their original measure. 

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 engage in an activity where one partner reads directions while the other follows those directions to complete a math task (such as bisecting an angle). As a reflection, they examine products to see what information the best...

Pupils compare and contrast two dimensional polygons and three dimentional nets by examining the differences in drawings. They create three dimensional shapes and label the faces, edges, and vertices. After creating the shapes, they draw...

Third graders engage in a lesson that focuses on the attributes and forming of a cube. They construct a cube using different combinations while comparing a square with only two-dimensions. Students fold paper while following the...

Students calculate the surface area of prisms. For 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.
