CCSS.MATH.CONTENT.2.MD.4 (0)
Measure and estimate lengths in standard units.
Education Level: 2
Description:

Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.

CCSS.MATH.CONTENT.2.MD.5 (0)
Relate addition and subtraction to length.
Education Level: 2
Description:

Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem.

CCSS.MATH.CONTENT.2.MD.6 (0)
Relate addition and subtraction to length.
Education Level: 2
Description:

Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, … , and represent whole-number sums and differences within 100 on a number line diagram.

CCSS.MATH.CONTENT.2.MD.7 (1)
Work with time and money.
Education Level: 2
Description:

Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.

CCSS.MATH.CONTENT.2.MD.8 (0)
Work with time and money.
Education Level: 2
Description:

Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ (dollars) and ¢ (cents) symbols appropriately. Example: If you have 2 dimes and 3 pennies, how many cents do you have?

CCSS.MATH.CONTENT.2.MD.9 (0)
Represent and interpret data.
Education Level: 2
Description:

Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units.

CCSS.MATH.CONTENT.2.NBT.1 (0)
Understand place value.
Education Level: 2
Description:

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).

CCSS.MATH.CONTENT.2.NBT.2 (0)
Understand place value.
Education Level: 2
Description:

Count within 1000; skip-count by 5s, 10s, and 100s.

CCSS.MATH.CONTENT.2.NBT.3 (0)
Understand place value.
Education Level: 2
Description:

Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.

CCSS.MATH.CONTENT.2.NBT.4 (0)
Understand place value.
Education Level: 2
Description:

Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.

CCSS.MATH.CONTENT.2.NBT.5 (1)
Use place value understanding and properties of operations to add and subtract.
Education Level: 2
Description:

Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

CCSS.MATH.CONTENT.2.NBT.6 (1)
Use place value understanding and properties of operations to add and subtract.
Education Level: 2
Description:

Add up to four two-digit numbers using strategies based on place value and properties of operations.

CCSS.MATH.CONTENT.2.NBT.7 (0)
Use place value understanding and properties of operations to add and subtract.
Education Level: 2
Description:

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 a 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.

CCSS.MATH.CONTENT.2.NBT.8 (0)
Use place value understanding and properties of operations to add and subtract.
Education Level: 2
Description:

Mentally add 10 or 100 to a given number 100-900, and mentally subtract 10 or 100 from a given number 100-900.

CCSS.MATH.CONTENT.2.NBT.9 (0)
Use place value understanding and properties of operations to add and subtract.
Education Level: 2
Description:

Explain why addition and subtraction strategies work, using place value and the properties of operations. (Explanations may be supported by drawings or objects.)
