In grade one, your child will be engaged in making sense of mathematical ideas. The Investigations 3 curriculum is designed to:
support students to make sense of mathematics and learn that they can be mathematical thinkers;
focus on computational fluency with whole numbers as a major goal;
provide substantive work in important areas of mathematics - rational numbers, geometry, measurement, data, and early algebra - and the connections among them;
emphasize reasoning about mathematical ideas;
communicate mathematics content;
engage the range of learners in understanding mathematics.

Investigations 3 Connection to Common Core Standards
According to the CCSS, rigor refers to "deep, authentic command of mathematical concepts" consisting of three aspects pursued with "equal intensity": conceptual understanding, procedural skill and fluency, and application:
Conceptual understanding: Students must be able to access concepts from a number of perspectives in order to see math as more than a set of mnemonics or discrete procedures.
Procedural skills and fluency: The standards call for speed and accuracy in calculation. Students must practice core skills, such as single-digit addition, in order to access more complex concepts and procedures.
Application: The standards call for students to use math in situations that require mathematical knowledge. Correctly applying mathematical knowledge depends on students having a solid conceptual understanding and procedural fluency.
Mathematical Practices
Investigations promotes a learning environment in which students learn that they are capable of having mathematical ideas, applying what they know to new situations, and thinking and reasoning about unfamiliar problems. Please find the Mathematical Practices chart here.
