Investigation--Can You Build This?
Early learners explore shapes using colored blocks. They first get some hands-on time with the blocks and then look at beginning math concepts regarding spatial relationships. They work with a partner to build a 6-8 block tower with...
ESL Kid Stuff
Numbers 1-20
Language learners engage in a series of games and activities designed to help them recognize and name the numbers from ten to twenty.

Building Buildings
Seventh graders investigate 2-D and 3-D objects. In this geometry instructional activity, 7th graders begin to understand spatial reasoning. Students look at pictures of the NYC Skyline and discuss what it looks like from different...
Cornell University
Scaling Down: Effects of Size on Behavior
Two activities explore the concept of size, especially small sizes down to the nano. Scholars practice determining volume, mass, and density and calculate exponential increases and decreases. They then predict and test the effect of size...

Exploring Projective Geometry
In this exploring projective geometry worksheet, students use computer software for instruction, then answer 9 questions about 3D drawings.
Curated OER
Awareness of Pre-Algebra Concepts
Young scholars demonstrate how to solve various algebraic equations. In this pre-algebra activity, students work in teams and use Borenson's Hands-On Equations materials to solve algebraic equations.
