For teachers, the Department of Education site also provides the Teacher's Toolkit, which helps explain the provisions of NCLB, and how it could affect you, including information about becoming a Highly Qualified Teacher.
You can also get FREE (I love that word) video workshops on topics, including:
Developing Computational Fluency in Addition and Subtraction
Early Steps Count: Teaching Arithmetic to Prepare Students for Algebra
Feedback: A Powerful Tool for Raising Student Achievement in Mathematics
Measurement and Geometry: Building Conceptual Understanding in Young Children
Patterns to Symbols: Algebra
Standards-Based Differentiated Math
Taking the "Dense" Out of Density
Using Technology to Enhance Algebra Instruction
