Geometry Workshop

On Saturday, January 20th, we hosted our geometry workshop at Logan Heights Library, where 35 girls learned all about two and three-dimensional shapes. After discussing our example woman in STEM, Emmy Noether, and her accomplishments in abstract algebra, the participants learned about various properties of triangles and quadrilaterals. They also earned prizes for answering questions such as naming types of triangles. Then, the girls proved that the angles of triangles add up to 180 degrees by folding the corners of paper triangles into a straight line. Before moving on to three-dimensional shapes, the girls learned about how proofs work and how mathematicians discover them. 
​
To begin our section on three-dimensional shapes, participants learned about types of prisms, pyramids, polyhedrons, and more! They then put this into action with paper nets, which showed how 3D shapes are made out of 2D shapes. After taking a quick break for snacks, we then moved on to examples of the math that the girls learned about in nature. Finally, the girls created modular origami and put 2D origami shapes together to make a variety of shapes including cubes and polyhedrons. One participant commented that “my favorite part was the origami because I liked making all the different shapes with paper.” Be sure to look out for our ecology workshop on February 17th!
