Transforming teaching practices to the new expectations can be challenging. MTB4 added support to help teachers make these transitions. MTB4 has an improved assessment structure, more discussion prompts to move learning forward, sample student answers, sample dialogs to address misconceptions, strategies to help teachers think about multiple ways to solve problems, conversations discussing the strategies and how to help students choose efficient ones, more visuals, more suggestions for meeting students’ needs, and more point-of-use information such as Content Notes and mathematical background in Mathematics in this Unit sections. Math Trailblazers is like having professional development at a teacher’s fingertips. There are now more strategies and support in students’ materials, too.
