Part of: Word Problems

Turn a word problem about word problems into symbols: names and units before formulas.

From words to math

Read the last sentence first so you know what the question asks for. Then label each number with what it measures. Word Problems connects the math to the full lesson.

Match words to operations

Words like “per,” “each,” “total,” and “leftover” point toward multiply, divide, add, or subtract—match the word to an operation, then write the expression.

Label everything

Underline the quantity you need to find. Circle every given number with its unit (miles, dollars, cups). Convert units before you add or subtract.
