Areas and Volumes - 2D Shapes
Unfortunately for young mathematicians, the world isn't made entirely of parallelograms, triangles, and trapezoids. After first learning the area formulas for these common shapes, students apply this new knowledge to determine the area...

Constructing and Visualizing Topographic Profiles
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...

Painting Package
Students use tools in a painting package to design tiles and create repeating patterns. They design a single tile using a 4 x 4 grid and experiment with changing the alignment of some of the tiles by rotating different areas.

Praire Biome Models
Fifth graders, in groups, list the physical characteristics of a biome and think of ways in which animals might have to adapt to live there and make a biome mobile ball that show the different types of habitats that shape the praire biome.
