Get the Math is an interactive website that tries to show the connection between real life and math. Math in Music shows how a rap artist/music producer would use ratios to create sample music beats. The site is interactive so you can make the music yourself.
Sites that I can't do without as a math teacher (and what's so special about each one!) Links to virtual manipulatives, discovery-based lessons, free graphing software, question prompts, eBooks, and more.... Tons of resources for math teachers
Graphagories Describing Graphs Game - Divide the class up into groups. Give each group a specific section of the dry erase board or give each group their own large dry erase board to write on at their desks. Project a graph on the board. Ss write as many descriptions of the graph as possible (a slope of 3, a y-int of 2...) If two teams have the same description, it gets knocked off the list.
