Place value, rounding & comparing numbers 4th Grade Math Unit 1a Place value, rounding & comparing numbers

Standards: Cluster: Generalize place value understanding for multi-digit whole numbers. MCC4.NBT.1 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. (DOK.3) MCC4.NBT.2 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. (DOK.3) MCC4.NBT.3 Use place value understanding to round multi-digit whole numbers to any place. (DOK.3)

SLM Unit 1 Part 1: Whole Numbers, Place Value and Rounding in Computation – Place Value Key Learning The student will understand the relative size of base-ten numerals in each place and place value up to one million. Unit EQ How do we understand the relative size of base-ten numerals in each place and place value up to one million? Concept Place Value Rounding Comparing Numbers Lesson EQ’s How do we represent numbers? (NBT.2) How do we read and write numbers in base-ten numerals? (NBT.2) How does the value of a digit compare to the same digit in the place to its left or right? (NBT.1) How do we round whole numbers to any place? (NBT.3) How does understanding place value help me explain my method for rounding a number to any place? (NBT.3) How do we compare numbers using greater than (>), less than (<), or equal to? (NBT.2) How can we determine the place value relationship? (NBT.1) Vocabulary Digits Value Place value names to million Base-ten numerals (standard) Number names (word) Expanded form Round Greater than (>) Less than (<) Equal to (=) Compare
