Geometry scavenger hunts can be tailored for students of all grade levels, as can projects that use circumference to investigate how far a bicycle can travel. Making paper snowflakes and toothpick structures introduces students to symmetry through geometric shapes.
Students of all levels can benefit from a geometry scavenger hunt, and there are multiple ways of structuring this project. One idea suggested by Education.com is to group students and have them photograph or draw different geometric shapes they see in and around the school. The students then compare their images with their classmates'. A teacher could easily tailor this project for younger students by preparing a list of geometric shapes for the students to find on their scavenger hunt.
Elementary students can apply the concepts of circumference and diameter to the real world through measuring bike or car tires. A more advanced version of this project has a student ride his bike, measure the distance traveled, and then calculate how many times the bicycle wheel went around by using the circumference of the wheel.
Elementary students can build geometric shapes out of toothpicks and Styrofoam balls or marshmallows. They can make triangles, squares, pentagons and hexagons and then use these to construct tetrahedrons, pyramids, cubes and prisms, in addition to other modular structures.
