Common Core Mathematics Unit Lesson Sequence th 5 Grade Unit 1: Understanding and Interpreting Place Value Disclaimer: The following sample unit is intended to provide an example of a possible flow of instruction. Consider this a work in progress. As a sample instructional plan, it should invite discussion and development. It is not intended to be prescriptive, only suggestive. It may provide ideas and guidance in the development of conceptual understanding through a sample sequence of lessons. This UNIT can be adapted, modified, expanded, delivered as-is, or not used at all. Lessons are not time bound, they may extend beyond a day. It simply provides an example unit of instruction which incorporates: Integration of the 8 mathematical practices for mathematics Investigative tasks Formative assessment and performance assessments In this unit, you will find that specific standards are NOT listed within each lesson, as lessons integrate multiple standards to better address conceptual understanding. Previous Concepts Grade Level Standard(s) Central to Lesson Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left. Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10. Fluently multiply multi-digit whole numbers using the standard algorithm.
