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.

How do you know you know? Prove it! The guide goes through several examples and includes a link to a video to teach learners how to work through coordinate proofs. The goal is to prove that different shapes are indeed that shape. 

Students learn the basic definitions of a quadrilateral, parallelogram, rectangle and square and explain the relationship/classification process between them.

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Students respond to Tony Smith's sculpture as art and brainstorm about math concepts inherent in his work. They create a sculpture with polyhedra nets, calculate the cost of covering sculpture in gold, and write an exhibit label for...

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.

Prisms are the focus of this geometry worksheet. Students count the number of parts of a prism and chart 26 answers. Vocabulary such as: "faces," "edges," and "verticies" are taught. A well-designed math worksheet!

Students 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 are...

Third graders engage in a instructional activity 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...

In this geometry worksheet, 10th graders measure different nets to figure out the shape they represent. They enlarge the nets, cut them out and create the shape to get their final answer. There are 10 nets with an answer key.

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...

Third graders utilize different types of computer programs, such as Microsoft paint and Microsoft Word to study and create different types of polygons. They use PowerPoint to create a story about a shape and others that it meets during a...

This PowerPoint addresses fifth grade math concepts, focusing mostly on geometry. The interactive math review game is in a "Jeopardy" style format and enables students to revisit the topics in geometry such as polygons, quadrilaterals...

Fifth graders solve problems while examining a variety of isosceles triangles.  In this isosceles triangle lesson, 5th graders examine shapes to find their characteristics.  Students pay particular attention to the...

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

Tenth graders experiment with gravity and air pressure. For this geometry lesson, 10th graders build their own kits and fly it. They investigate the questions: what keeps a kite in the air and what are some important factors when flying...

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

In this geometric figures worksheet, 10th graders solve and complete 11 different word problems. First, they find the area of a regular octagon with a given side. Then, students find the area of each shaded region. They also find the...

Students investigate technology and its purpose in the workplace. In this geometry lesson, students design and build a paper towel structure to investigate motion and forces. They are given a restricted weight and asked to build their...

Partners use materials to wrap three-dimensional objects to determine the formula for surface area. The groups use an orange to calculate the amount of peel it takes to completely cover the fruit. Using manipulatives, individuals then...

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

An outstanding lesson on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about triangle...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...
