Module 1: Number Sense

In this module, we cover most of the math “basics”. Getting comfortable with operations and order of operations will be important for virtually every other topic (including linear relations, geometry, and working with fractions and proportions). Further, having a good understanding of place value will also make operations like 3x2 digit multiplication and long-division with whole numbers and decimals a lot easier as well. As such, although the topics are considered math “basics”, these topics are worth a thorough review.
