Primary geometers create a picture using tangrams. In this geometry lesson, learners 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.

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...

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.

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

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

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 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.)

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

Third graders examine two-dimensional objects and create a 3-D image of the object. They make models of the Taj Mahal and buildings in Delhi.
