Common Core Mathematics Unit Lesson Sequence th 4 Grade Unit 1: Whole Numbers, Place Value and Rounding in Computation 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 and may extend beyond a day. It simply provides an example unit of instruction which incorporates: Integration of the 8 Mathematical Practices 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 whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division. Read and write multi‐digit whole numbers using base‐ten numerals, number names, and expanded form. Compare two multi‐digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons. Use place value understanding to round multi‐ digit whole numbers to any place. Use place value understanding and properties of operations to perform multi‐digit arithmetic. Upcoming Concept Use the four operations with whole numbers to solve problems. 4.OA.1 4.OA.2 4.OA.3 Solve problems involving measurement and conversion of measurements. 4.MD.2 4.MD.3 Generate and analyze patterns. 4.OA.4 4.OA.5 Common Core Mathematics Unit Lesson Sequence th 4 Grade Unit 1: Whole Numbers, Place Value and Rounding in Computation Fluently add and subtract multi‐digit whole numbers using the standard algorithm. Multiply a whole number of up to four digits by a one‐digit whole number, and multiply two two‐digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. Find whole‐number quotients and remainders with up to four‐digit dividends and one‐digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division.

Topic B: Comparing Multi-Digit Whole Numbers (4.NBT.2) 5 Students are asked to compare numbers based on Grade 4: Module 1 (Pgs. 1.B2-1.B.13) meanings of the digits, using >, <, or = to record the comparison. 6 Students will find 1, 10 and 100 thousand more and less Grade 4: Module 1 (Pgs. 1.B.14-1.B.24) than a given number. Topic C: Rounding Multi-Digit Whole Numbers (4.NBT.3) 7 Students are asked to round multi-digit numbers to the Grade 4: Module 1 (Pgs. 1.C.2-1.C.11) thousands place using the vertical number line. 8 Students are asked to round multi-digit numbers to any Grade 4: Module 1 (Pgs. 1.C.12-1.C.23) place using the vertical number line. 9 Students are asked to use their understanding of place Grade 4: Module 1 (Pgs. 1.C.24-1.C.34) value to round multi-digit numbers to any place value. 10 Students are asked to use their understanding of place Grade 4: Module 1 (Pgs. 1.C.35-1.C.46) value to round multi-digit numbers to any place value using real world applications.

For this reason, tasks from the Georgia Department of Education have been included to assist in addressing these two standards. 20 Students are asked to make diagrams to discover and Georgia Department of Education: demonstrate the answers to 2-digit to 4-digit multiplication Unit 2: Multiplication and Division of Whole Numbers story problems. This task provides opportunities for (Pgs. 58-63) students to work with arrays in real world situations as they work with larger numbers. 21 Students explore their understanding of multiplication and Georgia Department of Education: how it applies to multiplying 1-dgit and 2-digit numbers by Unit 2: Multiplication and Division of Whole Numbers up to 4-digit whole numbers. This task should be (Pgs. 64-69) completed before students have any experiences with the standard algorithm for multiplying two digit numbers.
