This workshop took place virtually on October 16.
Due to the high demand for our virtual teacher workshops, we split and run a lower-level workshops (designed for teachers of grades K-5) and an upper-level workshops (designed for teachers of grades 6-12). The page for the associated lower-level workshop is
Professional development credit certificates and stipends were be offered for this workshop.
However, a teacher may only obtain a certificate and stipend for the lower-level or upper-level workshop, but not both. (It is OK if someone wants to attend both workshops.)
Participants need to have a current W9 on file with Kansas State University to get the stipend. A copy of the W9 form is available at the bottom of this page. If someone was paid for a workshop in 2021, the W9 on file is still valid.
The workshop featured 90-minute mathematical activities/explorations led by Matthias Kawski and Amanda Serenevy.

Remainder Webs
We will explore the fascinating remainder patterns that emerge when converting fractions into decimal forms. When will most of the numbers form a single web and when will they split into separate groups?
Annihilating dots on a circle
Put red and blue dots on a purple circle. When a red dot moves on top of a blue one the resulting purple dot is lost. What happens?
