EngageNY - Module 2
Module 2 uses place value to unify measurement, rounding skills, and the standard algorithms for addition and subtraction. The module begins with plenty of hands-on experience using a variety of tools to build practical measurement skills and conceptual understanding of metric and time units. Estimation naturally surfaces through application; this transitions students into rounding. In the module’s final topics students round to assess whether or not their solutions to problems solved using the standard algorithms are reasonable.
