Understand Place Value
1. Understand that the
three digits of a three-digit number represent amounts of hundreds,
tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones.
Understand the following as special cases:
a. 100 can be thought of
as a bundle of ten tens — called a ―hundred.‖
b. The numbers 100, 200,
300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five,
six, seven, eight, or nine hundreds (and 0 tens and 0 ones).
2. Count within 1000;
skip-count by 5s, 10s, and 100s.
3. Read and write numbers
to 1000 using base-ten numerals, number names, and expanded form.
4. Compare two three-digit numbers based on meanings of
the hundreds, tens, and ones digits, using >, =, and < symbols to record
the results of comparisons.
Use place value understanding and properties of operations
to add and subtract.
5. Fluently add and subtract within 100 using
strategies based on place value, properties of operations, and/or
the relationship between addition and subtraction.
6. Add up to four two-digit numbers using
strategies based on place value and properties of operations.
7. Add and subtract within 1000, using concrete
models or drawings and strategies based on place value, properties
of operations, and/or the relationship between addition and
subtraction; relate the strategy to written method. Understand that
in adding or subtracting three-digit numbers, one adds or subtracts
hundreds and hundreds, tens and tens, ones and ones; and sometimes
it is necessary to compose or decompose tens or hundreds.
8. Mentally add 10 or 100 to a given number 100–900,
and mentally subtract 10 or 100 from a given number 100–900.
9. Explain why
addition and subtraction strategies work, using place value and the
properties of operations.
