Middle schoolers build a three-dimensional 12-pointed star as a geometric exercise. The shape is quite-difficult to construct. Luckily there is an excellent template that learners cut out, then use to make their pyramid. The second part...

Learners examine the rhombi or diamond shape and compare it to the square. Students are challenged to create as many flat rhombus shapes as possible and develop a definition for the rhombus shape in 20 minutes while working in teams of...

Students explore geometry by completing a marshmallow activity in class. In this architecture lesson, students identify the jobs of civil engineers and architects while identifying different geometric shapes as well. Students utilize...
