This task is intended to help model a concrete situation with geometry. Placing the seven pennies in a circular pattern is a concrete and fun experiment which leads to a genuine mathematical question: does the physical model with pennies give insight into what happens with seven circles in the plane?

Meet Bay Area artist Mike Shine, who discusses his carnival-inspired paintings, and his recent large-scale stencil murals. He makes art for people to enjoy, both superficially and in depth, and condemns much of modern art because of the context needed for interpretation. He wants his art to be able to be interpreted, regardless of how it is interpreted. He wants it to transcend cultural and language barriers. Check out how his art is made in this video.

In this activity learners explore the connections of digital time displays with numeric and geometric properties. Students look for times that have bilateral or rotational symmetry, or have a certain digital sum, etc. Ideas for implementation, extension and support are included.

Have you ever thought about the mathematics of beading? This challenge will have you thinking about symmetry and all of the ways you can create different necklaces with the same beads.
