Investigations 3 is a focused, coherent, and rigorous K-5 mathematics curriculum. Fully aligned to the content and practice standards of the Common Core State Standards (CCSS), deep and careful attention is paid to mathematics content and to student thinking and understanding. Making sense of mathematics is the heart of the work, for students and teachers.
The culmination of over 25 years of research and development aimed at improving the teaching and learning of elementary mathematics, Investigations 3 maintains and builds on the philosophy and pedagogy of the first and second editions, and continues to be based on the work of real teachers and students. The goals remain the same, as do the underlying guiding principles.
