We in the US are failing our students. We are failing to teach them elementary mathematics. 

As a result, we are shutting off their ability to succeed in algebra and beyond. 

Most elementary math textbooks in the US offer shallow, incoherent curricula filled with analogies and tricks rather than reasoning. They offer a glimpse at conceptual understanding, but deny students enough practice to achieve mastery. They contain procedural strategies without explanation. They contain labor-intensive discussions without defining mathematical terms.They fail to give students the knowledge of why a result is true. 

MSMI exists to help teachers, schools, and parents ensure their students are prepared for algebra and beyond. We show how to teach your students that mathematics is a coherent, sequential set of truths that gives them the tools to reason. We show how to teach arithmetic, fractions, decimals, and pre-algebra in ways that makes sense, so students know that math is learnable with effort. We help educators increase their content knowledge and their confidence. We help schools adapt to changing standards and requirements. We help parents to know if their students have received the preparation they need for algebra and beyond.
