determining a number when given the value of ones, tens, and
hundreds.
Example: expanding—recognizing 251 as being represented by two
hundred fifty-one,
by 2 hundreds + 5 tens + 1 one, and by 200 + 50+ 1

• Identifying zero as a placeholder in two- and three-digit numbers
• Comparing numbers using the symbols >, <, and =
Adding and Subtracting

subtraction, regrouping, sum,
difference, total.
Solve two-digit addition and
subtraction
Quick Recall of Math Facts
Demonstrating computational fluency,
including quick recall, of addition and

20 and differences with minuends
through 20.
Money-Money-Money-Money
Penny is one cent.
Dime is ten cents.
Nickel is five cents.
Demonstrating computational
fluency, including quick recall, of

unlike sets of coins and bills up to $2.00.
• Identifying sets of coins of equivalent value
• Selecting coins to make equivalent sets
• Applying monetary symbols, including
dollar ($), cent (¢), and decimal point (.)
• Recognizing decimal numbers .10, .25,
.50, and .75 as related to money
Associative Property of Addition
Recognize the associative property of addition.
 Example: (3 + 4) + 2 = 3 + (4 + 2)

When adding 3 or more numbers, we can add the digits in any order, and the
answer will always be the same. .
3 + (5+4)
3 + 9
is the same as...
(2+5)+3 = 2+(5+3)
(3+5)+ 4
8
+ 4
7+3
=
2+8
10 = 10


Vocabulary- data, diagram, graph
How many students prefer the
