Use the four operations with whole numbers to solve problems.2
4.OA.3 Solve multistep word problems posed with whole numbers and having whole-number
answers using the four operations, including problems in which remainders must be
interpreted. Represent these problems using equations with a letter standing for the
unknown quantity. Assess the reasonableness of answers using mental computation and
estimation strategies including rounding.

Generalize place value understanding for multi-digit whole numbers. (Grade 4 expectations
are limited to whole numbers less than or equal to 1,000,000.)
4.NBT.1 Recognize that in a multi-digit whole number, a digit in one place represents ten times what it
represents in the place to its right. 
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 meanings of the digits in each
place, using >, =, and < symbols to record the results of comparisons.
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.
4.NBT.4 Fluently add and subtract multi-digit whole numbers using the standard algorithm

4.MD.13 Know relative sizes of measurement units within one system of units including km, m, cm; kg,
g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements
in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column
table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a
4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs
(1, 12), (2, 24), (3, 36), …

4.MD.24 Use the four operations to solve word problems involving distances, intervals of time, liquid
volumes, masses of objects, and money, including problems involving simple fractions or
decimals, and problems that require expressing measurements given in a larger unit in terms
of a smaller unit. Represent measurement quantities using diagrams such as number line
diagrams that feature a measurement scale.
