• CHAPTER 1: PLACE VALUE, ADD & SUBTRACT TO A MILLION

    In Chapter 1 students will:
    • Model the 10-1 relationship among place-value positions in the base-ten number system
    • Read and write whole numbers in standard, word, and expanded form
    • Compare and order whole numbers
    • Round a whole number to any place
    • Add & subtract whole numbers; use estimation to determine if solutions are reasonable

    Vocabulary:
    • place value – the value of a digit in a number, based on the location of the digit
    • digit – any single number; 0-9
    • standard form – a way to write numbers by using the digits 0-9 with each digit having a place value
    • word form – a way to write numbers by using words
    • expanded form – a way to write numbers by showing the value of each digit
    • period – each group of three digits separated by commas in a multi-digit number
    • addend –  any number used to add
    • sum –  the answer to an addition problem
    • difference –  the answer to a subtraction problem
    • compare –  to describe whether numbers are equal to, less than, or greater than each other
    • order –  a particular arrangement or placement of things one after the other
    • estimate – a number close to an exact amount
    • round – to replace a number with another number that tells about how many or how much

    Chapter 1 Standards:  Number and Operations in Base Ten

    Generalize place value understanding for multi-digit whole numbers; 
    CC.4.NBT.1    Recognize that in a multi-digit while number, a digit in one place represents ten times what it represents in the place to its right.

    Generalize place value understanding for multi-digit whole numbers; 
    CC.4.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 meaning of the digits in each place using >, =, and < symbols to record the results of comparisons.

    Generalize place value understanding for multi-digit whole numbers; 
    CC.4.NBT.3    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;  
    CC.4.NBT.4     Fluently add and subtract multi-digit whole numbers using the standard algorithm.
