Shapes: Art or Geometry
Budding artists or mathematicians read about,and then draw, two very different shapes. Geometric and organic 2-D shapes are defined. Learners use the definitions to draw examples of each.

Artistic Angles
Fifth graders explore angles by using protractors. They recognize, describe and determine the surface area and volume of three-dimensional shapes. Students recognize the right angle, acute angle, obtuse angle and vertex. They identify...

Create, Classify, and Sort Quadrilaterals
Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among...

Dihedral Figures
Middle and high schoolers perform transformations. In this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.
Curated OER
Don't Box Me In
Students explore the relationship between flat and three-dimensional shapes. They identify the names of 3-D shapes and construct cubes from squares.
Curated OER
Down The Line
Learnersinvestigate three-dimensional shapes. In this geometry lesson plan, pupils calculate the volume of cylinders using the given dimensions. They create a formula base don observation before using the real formula.
Curated OER
Copy Cat
Students examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.
Curated OER
Putting It All Together
Students complete activities to learn about the shapes and their vertices. In this shape recognition lesson, students discover the rule linking the number of sides with the number of vertices for shapes. Students categorize...
Curated OER
A Sphere and Its Net
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.
Curated OER
Shapes
Discuss the properties of 2D and 3D shapes in order to help learners understand the concept. Learners will participate in an interactive whiteboard lesson plan to develop understanding of 2D and 3D shapes.
Curated OER
Circle Art
Students investigate two and three dimensional shapes. In this geometry lesson, students write equations of circles and graph them correctly. They create pictures using circles.
Curated OER
Cubes Everywhere
Young scholars use cubes to construct and visualize two-and three-dimensional shapes to develop spatial thinking and review basic geometric principles through real-life applications. They are given the opportunity to build and build and...
