Mathalicious "At Mathalicious, we believe that math isn’t something to learn, but a tool to learn about other things. Our mission is to help transform the way math is taught by providing you with the best, most meaningful and most relevant math content available. Our lessons are aligned to traditional state standards but, unlike most content, emphasize conceptual understanding through engaging realworld applications.What does this mean for you and your students? It means you can use linear equations to pick the right cell phone plan, and percents to get healthier. It means you can use proportions to compare the iPhone and the iPad, and explore whether the Olympics are fair. Our approach means that you as a teacher can foster real conversations, real learning about topics that students really care about."
