Operations and Algebraic Thinking
Use the four operations with whole numbers to solve problems.
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.

Read a division word problem and decide what the quotient is telling you in the story. Figure out what to do with a remainder (share it, ignore it, or round up) so the answer makes sense.

Decide which two operations are needed to solve a multi-step word problem. Multiply 3-digit by 1-digit and 2-digit by 2-digit numbers within a problem. Combine multiplication with addition or subtraction to find a final answer. Use the context of the problem to check that an answer is reasonable.

Divide multi-digit numbers by one- and two-digit divisors. Decide what the remainder means in the context of a problem. Choose between the quotient, the remainder, rounding up, or the amount needed to fill the last group.

Decide whether to add, subtract, multiply, or divide to solve a word problem. Pull out the important numbers and clues from a story problem and ignore extra details.

Solve word problems that take two steps, where you multiply first and then divide. Figure out what the problem is asking and choose the correct numbers and operations. Write and solve a matching equation for a story problem using multiplication and division.

Find the value of a letter that makes a given equation true. Work with all four operations in one set of problems. Read an equation that has the unknown inside it rather than alone on one side.
