We had a great day today, met new friends, did some fine math, and had a helpful discussion about standards, testing, and finding a balance/ the time to teach mathematical processes (problems solving).

A special thank you to

  • Bob Klein for making the trek from OU to run our morning session! Hope you found something worthwhile at IKEA! And find the time to come back soon.
  • Steve Phelps for presenting a session on Liar's Bingo along with explicit ideas about using the activity in grades 7-9 or so.
  • Linda Bollman for facilitating and moderating our reflections on pedagogy and core content standards
  • Linda Bollman and CHCA staff for making arrangements and provisions to host our workshop at the CHCA Middle School!

Below is the initial announcement of our meeting.

Our Winter Workshop was on Saturday January 26 from 8:30 to 2:30 at Cincinnati Hills Christian Academy Middle School.

There is no cost to attend, but we need to have a count for food and materials so would like everyone who plans to attend to register at http://cincymathcircle.eventbrite.com/

Come join us for math, coffee, problem-solving, and Common Core discussions at our
Cincinnati Math Teacher Circle Winter Workshop!**
We will explore some non-intuitive probability ideas by investigating the mathematics of non-standard dice in a kinesthetic way.

Join us for this FREE Math Circle Workshop! Coffee, breakfast snacks, and a light lunch will be included (courtesy of the University of Cincinnati's Department of Mathematics MAT program).

Our morning Math Circle session will focus on non-intuitive probablity explorations involving non-standard dice, followed by a discussion of the Common Core Mathematical Practices and problem-solving.
Our afternoon sessions will consist of Mini-Math Circles. You will have your choice of sessions about Exploding Dots, Paper-folding, Liars Bingo, Problem-Solving, and others.

What did you miss at the first THREE Cincinnati Math Teacher Circles?
You missed an exploration of a concrete representation of different number bases that was used to model polynomial division. You missed an opportunity to explore a mathematical card game that naturally led to question of probability and to a 4-dimensional geometry. You missed a mathematical investigation of tangled ropes that led to rational number computations. You missed rich discussions
with passioned mathematics educators around the Common Core State Standards for Mathematics.
