Lessons 1 & 2: Each place on a Place Value Chart is 10 times larger than the place to the
right. 

Lessons 1 & 2: Each place on a Place Value Chart is 10 times smaller than the place to the left.


Lesson 3: Write numbers in word form & standard form with the help of commas


Lesson 4: Using place value to write numbers in expanded form.

Expanded Form


Lesson 5: Using <,>,= symbols and place value to compare digits


Lesson 6: Finding 1, 10,or 100 thousand more or less than a given digit


Lesson 7: Use a number line model to round


Lesson 8 & 9: Using a number line to round to a specific place. Remember a number line can be drawn horizontally or vertically


Lesson 10: Rounding with real world problems


Lesson 11: Using place value to understand the addition algorithm


Lesson 12: Using rounding to check for reasonableness of your sum


Lesson 13: Using place value to understand the subtraction algorithm


Lesson 14 & 15: Using the bar diagram to subtract


Lesson 16: Solve two step real world word problems with bar diagram (aka tape diagram)


Lesson 17: Using a bar model to solve a comparison word problem


Lesson 18: Using rounding to check for reasonableness of addition word problem


Lesson 18: Using rounding to check for reasonableness of subtraction word problem


Lesson 19: Solve addition word problems using a variable


Lesson 19: Solve subtraction word problems using a variable


Word Problems using a Bar Model (aka Tape Diagram) and the RDWW strategy we use in class:
Read the word problem & extract (underline) the information needed to solve the problem Draw picture to represent the problem Write a number sentence horizontally to represent your drawing Write an explanation of your answer to check for reasonableness 
This strategy is used throughout the Common Core curriculum to solve word problems

In this unit students will:
 read numbers correctly through the millions
 write numbers correctly through millions in standard form
 write numbers correctly through millions in expanded form
 identify the place value name for multidigit whole numbers
 identify the place value locations for multidigit whole numbers
 round multidigit whole numbers to any place
 solve multistep problems using the four operations
Common Core Objectives covered and tested on in this unit are:
Operations and Algebraic Thinking (OA)  Use the four operations with whole numbers to solve problems.
Please click the following links for videos, practice worksheets and online games to practice core content.
 4OA.3.a  I can use what I know about addition, subtraction, multiplication and division to solve multistep word problems involving whole numbers.
 4.OA.3.b  I can represent word problems by using equations with a letter standing for the unknown number.
 4OA.3.c  I can determine how reasonable my answers to word problems are by using estimation, mental math and rounding.
Numbers is Base Ten (NBT)  Generalize place value understanding for multidigit whole numbers.
Please click the following links for videos, practice worksheets and online games to practice core content.
 MCC4.NBT.1 Recognize that in a multidigit 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.
 MCC4.NBT.2 Read and write multidigit whole numbers using baseten numerals, number names, and expanded form. Compare two multidigit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
 MCC4.NBT.3 Use place value understanding to round multidigit whole numbers to any place. Use place value understanding and properties of operations to perform multidigit arithmetic.
 MCC4.NBT.4 Fluently add and subtract multidigit whole numbers using the standard algorithm.
