Explore the relationship between 2D and 3D shapes by having your class view representation of shapes and investigate their symmetry. They will create a solid object from diagrams and describe the reflection or rotational symmetry. In the...

Militaries throughout history have used topography information to plan strategies, yet many pupils today don't understand it. Scholars use Legos and a contour gauge to understand how to construct and visualize topographic profiles. This...

Sew up pupil interest with an engaging, hands-on lesson plan. Learners first design a sports bag given constraints on the dimensions of fabric. They then evaluate provided sample responses to identify strengths and weaknesses of included...

Primary geometers create a picture using tangrams. In this geometry lesson, students read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their tangram pieces.

Third graders describe 2D and 3D shapes. In this geometry lesson, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see what they have in...

Visit the Magic Treehouse and take your class on a trip through time with a reading of the children's book Mummies in the Morning. Using the story to spark an investigation into Egyptian culture, this literature unit engages...

How  does the shape of the surface of water in a container change as water leaks out? After tackling this question, learners take part in a similar activity with more complex figures.

Create three dimensional objects in an applied science lesson. The goal is for your class to recognize, compare, and model shapes. Using cookie cutters and clay or play dough, they create models for three-dimensional shapes.

Can we learn a thing or two about history by looking at pictures from the past? As young historians view 2-D and 3-D primary source photographs, they respond to a series of worksheets that guides them toward unveiling clues...

Seventh graders investigate the area and volume of 2D and 3D figures. In this geometry instructional activity, 7th graders create a storyboard explaining their knowledge of 2D and 3D shapes. They analyze their data and interpret...

Students distinguish between 2D and 3D elements in Escobar's work, explore assemblage, and identify the feelings expressed in Escobar's sculpture.

Learners create a three dimensional model of a cell. In this cellular structure instructional activity, students use gelatin, plastic bags, plastic containers, and fruit to construct a model of a cell. They compare the cells structures...

Discover the difference between standard and non-standard units of measure with your class. They differentiate between rectangles and squares, read a book, measure a peer's height. They then discuss  measurement methods, make...

Students describe the cell as a 3D object rather than the 2D object they are accustomed to observing. They describe the appearance and location within the cell of the various cell organelles.

Ask elementary students to explore shapes in everyday objects. They will discuss the elements of design and describe the shapes they see in visual images. Students will then design and "build" a new 3D shape. Finally they will show and...

Students explore geometric solids. In this geometry lesson, students listen to the book The Greedy Triangle by Marilyn Burns, then work in groups to sort geometric solids into various categories. Students define geometric solids...

Students observe the growing stages of plants. In this plant growth lesson, students collect, germinate, and plant seeds to chart the growth process of plants.

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Young scholars investigate how natural dyes from plants was an expression of Native American cultures. They examine objects dyed from natural sources, conduct Internet research, and create their own dyes using various plant sources.

Students examine two- and three-dimensional shapes and figures. Individually, they practice identifying the shape from various viewpoints. By completing this activity, they develop a spatial sense about how figures and shapes are...

Students research tall buildings and identify the geometric shapes used in the construction of the buildings. They compare shapes and infer why some are better than others in building. They produce a multimedia presentation of geometric...

Students investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)

Students use their understanding of 3D on 2D to make a representation of a 4D form on paper.

In this exploring projective geometry worksheet, learners use computer software for instruction, then answer 9 questions about 3D drawings.
