Yesterday's DEI training at New Teacher Induction was fantastic. Great job, Lindley and APS facilitators! The young teachers are so much more aware than I was when I started. They give me hope!
Getting ready to meet with APS's new Math Assessment Committee this week. Can't wait to see these teachers and get our work started!
Spent half an hour helping my son use scissors to discover the formula for the area of a parallelogram. Then he watched the video that was assigned, which justifies the formula with a 10-second animation. Sense-making takes work!
APS is looking for a math coach to join our team. I can't wait to start working with that person!

Ms. Bompadre's 2nd grade mathematicians used lots of different strategies to solve today's application problem.
Ms. Harrington's Kindergarten mathematicians at Lindley model number relationships with physical number bonds.
Mr. Grenon at Lindley led his 7th grade mathematicians in a discussion about student strategies for finding the area of part of a circle. This student work shows understanding of how the part relates to the whole circle.
A great example of how math for social justice can help us all look deeper, and why math is so important for every citizen of a democracy.
Pre-2010, 50g of crack-cocaine got you a mandatory minimum 10 years in prison.
Post-2010, that threshold was raised to 280g, which resulted in this .... uhhh suspicious drug seizure graph.

ALT pre 2010, pretty reasonable power law graph
ALT post 2010, pretty reasonable power law graph, except for a huge spike right at the 280g threshold
For math teachers who grew up in a procedural answer-getting tradition, there is a real challenge in understanding a conceptual approach to learning mathematics. How might we learn to see the "new ways" as something deeper than just another procedure? #MTBoS
Mrs. Ross at Tacony facilitated a discussion about her 3rd graders' attempts to cut a paper into 6 equal pieces. What do you notice? Are these pieces equal? How do you know?
An amazing day of lesson internalization at Lindley today. Fantastic teachers + fantastic curriculum = math that inspires!
Powerful questioning by Mrs. Troiani today...
T: Is there a pattern?
S: No because there's no straight line.
T: If I bought a 6000-lb truck, could you guess the fuel efficiency?
S: Yes.
T: Is there a pattern?
S: Oh yeah, the heavier the truck, the lower the efficiency!

Great online scavenger hunt if you are looking to share the Coherence Map with colleagues. Quick, fun, and walks you through many of the map's different features. #coreadvocates #MTBoS
There might not be treasure buried near a lake, but the Coherence Map has so much to offer math educators! Our online Scavenger Hunt is a great professional learning activity either on one's own or with a team. Find it: bit.ly/34Jeyde #iteachmath #ownthelearning
