Yummy Math is a new site I just learned about from one of it's founders, Brian Marks. The site is run by Brian, a math instructional coach, and Leslie Lewis, a retired math teacher.
The site provides free activities and ideas to relate math concepts with real life. Math is much more interesting and easier to learn when it is in the context of something familiar to the students, like sports and games.
They have the activities written to correspond with standards and sorted by math topic, like Algebra, Geometry, Math and Science, and much more.
This is a great resource for anyone who has math in their class.
