Geometric shapes make great visual models for introducing young mathematicians to the concept of fractions. Looking at a series of four circles, students are asked to determine whether or not one half of each circle is shaded. To support...

Comparing the movement of graphs geometrically when small changes are made to the parent function motivates this collaborative discussion on the transformations of functions to their various forms. Vertical and horizontal shifts due to...

Learners explore mapping a rectangle onto itself using rigid motion concepts, geometric intuition and experimenting with manipulatives in a collaborative task.

Time to move into the third dimension! Learn the names of the geometric solids and count faces, edges, and vertices. Then learn to recognize nets that create a given solid. 

Conquer any irrational fears you might have of irrational numbers. As class members investigate how to represent numbers geometrically, they learn about rational and irrational numbers, including approximating and ordering rational...

Combine algebraic and geometric strategies to find solutions. The task asks learners to find the coordinates of a third vertex of a triangle to create a triangle with a specific area. The project is a set of seven problems that...

What's in a triangle? Just 180 degrees worth of angles! Young learners use given angle relationships in a triangle to write an algebraic representation. Using a system of equations, they simplify the equation to a linear representation.

Use of the resource = Opportunities for increased learning. Learners must use equations and inequalities to solve real-world and geometric problems.

Investigate the components of vectors and vector addition through geometric representations. Pupils learn the parallelogram rule for adding vectors and demonstrate their understanding graphically. They utilize the correct notation and...

Students reconstruct an ancient Greek sculpture using various geometric forms and explore different geometric forms. They create an abstract human form out of geometric shapes and create other representations out of the same shapes.

Pupils examine and discuss the use of symmetry in a painting by the artist Roger Brown. They draw a geometric shape, divide it with a line of symmetry, and create a painting using the geometric shapes demonstrating symmetry.

Pupils predict what geometric shapes they think would be on the battleship; then view a picture and identify the various shapes they see. They take a tour of the battleship Wisconsin they identify various geometric shapes represented by...

Students investigate geometric shapes in their environment, make a geometric design, and write paragraphs describing the design.

Young scholars create wrapping clothes using paper or cloth scraps being sure to find or make geometric shapes. They create a visually balanced composition including symmetry,and repeated patterns.

Second graders explore how musical instruments h ave varying geometric shape, and how those geometric shapes correspond to three-dimenaional shapes that students have studied.

Students study geometric, naturalistic, and abstract shapes in art. They review the names of shapes and name them in the portrait, Breakfast in Bed by Mary Cassatt. They simulate a baby as in the portrait and discuss the shapes. They...

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

Fourth graders use computer drawing tools to create a house of geometric shapes.

Students investigate the use of Geometer's Sketchpad when studying geometric terms. They use the visualization tools to complete worksheet and design a picture to print and share with the class.

Students listen to a poem that includes directions to use geometric figures to complete a creative task.

Students explore two dimensional geometric figures. They explore the relationships and measurements of geometric figures. Students apply proportion and scaling. They design a city park for students and teenagers.

Students participate in a unit on triangles. Through the unit they explore different way to make basic shapes using triangles. They also examine the basic properties of triangles and the relationships among basic geometrical shapes in...

High schoolers explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. High schoolers identify different geometric...

Learners identify and create shapes. In this geometric shapes lesson plan, students identify various polygons and try to create new shapes using existing polygons.
