One of the most influential mentors I’ve had is @akademic67.bsky.social. Her ideas, her depth of care, her fight, her wit, and-of course-her shoes…all unparalleled and impeccable. Everything she is and does for kids, for teachers, for education is what we should all aspire to be and do. #NCSM25

All set up and ready for the first day of teaching this semester. Can’t wait to meet the new group of @butleru.bsky.social COE students! #iteachmath #edusky

The picture shows a classroom at Butler University. There are eight tables in the room. Three tables have table tents on them for students to create name plates. Five tables have provocations prepared to engage students in thinking about math. Tools at the provocation stations include foam cubes, Legos, game pieces, number cards, and a box of items for counting collections.
