Bold Bridges
Students explore bridge construction. In this bridge building activity, students view bridge websites and discuss how bridges are designed and built. Students design and construct their own bridge using the directions provided.
Curated OER
Exploration with Geometric Solids
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.
