Cluster:
Understand place value.

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

Cluster:
Use place value understanding and properties of operations to add and subtract.

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

Cluster:
Use place value understanding and properties of operations to add and subtract.

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

Cluster:
Use place value understanding and properties of operations to add and subtract.

Standard:
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.

Cluster:
Use place value understanding and properties of operations to add and subtract.

Standard:
Use estimation strategies to make reasonable estimates in problem solving. CA

Cluster:
Use place value understanding and properties of operations to add and subtract.

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

Cluster:
Use place value understanding and properties of operations to add and subtract.

Standard:
Explain why addition and subtraction strategies work, using place value and the properties of operations.

Footnote:
Explanations may be supported by drawings or objects.

Cluster:
Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.

Standard:
Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.

Cluster:
Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.

Standard:
Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.

Footnote:
Excludes compound units such as cm^3 and finding the geometric volume of a container. Excludes multiplicative comparison problems (problems involving notions of “times as much”; see Glossary, Table 2).

Cluster:
Represent and interpret data.

Standard:
Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.
