My first PD.
I just led my first PD on Number Talks for a group of K-5 teachers at a grade school. I am seriously floating inside a happy mathy bubble right now. Hopefully, it doesn't get popped for awhile. :) The school had early dismissal (after some Valentine's Day parties) and we tackled some number talks during the afternoon. The teachers were so enthusiastic, excited, and hard-working.
Why Number Talks?
I think "Number Talks" made an easy topic for an afternoon PD for a several reasons.
What is a Number Talk?
A number talk is intended to be a short talk about numerical reasoning, ranging from identifying numbers in kindergarten to two or three digit multiplication in fifth grade. A number talk is not meant to replace curriculum, but rather to support instructional practices by providing a daily routine that embraces students sharing their thinking. Number talks are often connected to visual representations, like 10-frames, arrays, or number lines. The number talks book shown below is one resource available for learning to use number talks. This book contains instructions of how to conduct number talks and samples of number talks. The book also has an accompanying DVD that has about 3 classroom number talks per grade level and teacher testimony.
Outline of the PD.
I asked the teachers to share multiple strategies. I asked them to explain others' reasoning and explain why it worked. I also asked them to connect the strategies to visual representations (like an area model or array).
Best. Day. Ever.
Not only were the teacher's super awesome and the PD fun, but the 5th grade class also gave me a bag of Valentine's (and candy)! So awesome.
