Learners examine various "spaces" (including ones that are one-dimensional, two-dimensional, and three-dimensional). For each space, they will examine what it means to have or not have an edge, or to be finite or infinite.

Third graders experiment with, identify, and follow teacher-directed instruction toward understanding two-dimensional geometric shapes found within the environment. Groups of students utilize geoboards to help them explain geometric shapes.

Students identify and sort a variety of two- and three-dimensional objects and compare and contrast their attributes. They identify shapes, locate shapes on the faces of solids, sort real objects and explain the sorting rule, and...

Pupils complete worksheets where they calculate the perimeter of polygons. In this perimeter of polygons lesson plan, students divide complex shapes into simple shapes to find the perimeter.

Students examine Holocaust memorials to discover expressive power of shapes, practice creating simple geometric shapes or forms, and practice calculating ratios, area, and/or volume.

Young scholars create a Holocaust memorial. In this interdisciplinary instructional activity, students use geometric shapes or forms to create a Holocaust monument.

Third graders draw shapes that are congruent. In this congruency lesson, 3rd graders use grid paper to draw letters and figures and their congruent partners. They complete a worksheet while working in a whole class setting with the...

Pupils investigate triangles. In this shapes geometry lesson, students define and state the attributes for equilateral, scalene, and isosceles triangles. Pupils locate the prefix "tri" in a variety of words and make connections with the...

Students discover how crystal structures go together to create minerals.  In this earth science lesson plan, students work in groups to create 3-dimensional shapes of crystals that they then put together in a compact structure.

Third graders explore vocabulary associated with three dimensional figures.  In this transformations lesson, 3rd graders create two dimensional nets for three dimensional figures.  Students become familiar with describing two...

Tenth graders investigate the history of geometry and its different shapes. In this geometry lesson, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the new materials...

Learners identify basic geometric shapes. In this geometry lesson, students read the book Shapetown and identify the various shapes from the story. Learners are given a sheet and draw part of a town using only shapes.

High schoolers analyze characteristics and properties of two and three-dimensional shapes in this geometry lesson. They follow detailed directions to use the Cabri Geometry II Application on their TI-89 calculator to construct a...

Learners construct 3-dimensional structures from 2-dimensional paper. They design and compile their structures to resemble a neighborhood community.

Maps can be so much fun, they help you understand spatial relationships, distance between objects, and can foster direction skills. Budding cartographers with visual impairments use the Wheatley Tactile Diagramming Kit to create their...

Students explore media and techniques to create works of art

Students use light and shadow information to make inferences regarding the three dimensional shapes of specific objects photographed on the surface of Mars. Limitations of the of the data provided are discussed and entries made into the...

In this planes worksheet, students consider the position of given vectors and find the vector equation of a plane. They identify the points that lie on a plane and determine the equation of a line through given points. This two-page...

Learners examine lines of symmetry with different shapes. Then students create their own books of symmetry with different two-dimensional shapes on each page.

Sixth graders use number cubes to explore volume of two-dimensional shapes. They roll a die and construct a shape using the numbers rolled as measurements of the sides. They estimate the volume of a given object, and then use the...

Students work with three dimensional objects. In this geometry lesson, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

The history of math is fascinating! Utilize a woodcut primary source image from 1492 and posters from the 1930s to help geometers apply their volume-calculation skills to real-life questions.
