Seventh graders explore the characteristics of three-dimensional figures. They compare the nets of figures. Students describe the relationship between the nets draw and the solid. They identify the vertices, edges and faces of the...

Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.

Students create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson series supports children with learning how to measure the area of squares, rectangles, and other...

In need of some dot paper for your next geometry lesson? Then look no further. This simple template allows you to maintain a classroom supply of this special paper for whenever the need arises.

Three activities make up a solar system lesson that features the sun, its light, and the shadows it produces. Scholars step outside to discover the changes shadows make at different times of day, take part in a demonstration of...

Students explore two-dimensional and solid shapes. In this shapes and patterns geometry lesson, students work with a partner to create identifiable objects using tangrams. Students describe the attributes of their shape and their partner...

Upper elementary and middle schoolers explore the properties of various polygons. They use video, resource links, and engage in hands-on activities in order to construct geometric nets. This fine plan should lead to increased...

Third graders consider space and the techniques artists use to create three-dimensionality within a painting or drawing. They examine works by Millet, Bruegel and Demuth and then create original drawings that explore the effects of...

Learners, during this twelve week series of lessons, learn basic anatomy through life sketches of human skeletons and shells. They learn fundamentals of line and convey life through sketches learning science through art.

Learners identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.

Learners explore finding the surface area and volume of cubes and cylinders. They construct similar three-dimensional figures from a two-dimensional drawing. Students derive the formula for volume and surface area through examination...

Students critique their own drawings for accuracy and make constructive suggestions prior to reworking them. They discover how scale in maps and drawing relate to relative size and distance. In addition, students comprehend the...
