I attended a presentation at the NCTM conference in April about UDL.  It's a new spin on an age-old concept of differentiation and how people learn best.  It's definitely something for me to think about in terms of curriculum, delivery, and assessment.

Curriculum Analysis Tool and Professional Development Materials from NCSM.  This will save so much time with selecting materials aligned with the standards, independent of what the publishers claim.  

Carnegie Museum of Natural History has a new teacher loyalty program that gives teachers free and exclusive benefits.  All you have to do is give your name, address, and place of employment.  What a great opportunity! 

This has videos of rich math tasks being used in classrooms, and takes you through the preplanning, launch-explore-summarize of the lesson, and the reflection after the lesson. Student work samples from the actual videos are also available.   It's a great resource for coaches and teachers for professional development.
