Students solve interesting problems and do the work of real mathematicians. They work actively and collaboratively with their peers to make sense of concepts, while using multiple representations and tools to solve complex problems. The materials’ visuals are bright and engaging, the real-world contexts are fun, and the problems are worth solving. Games, labs, and Workshops capture and keep young students’ attention as they practice important math skills. A Math Trailblazers classroom is filled with a feeling of excitement and discovery.
