Students add and subtract within 1,000 in join, separate, compare, and missing-number stories. They choose the operation from the story and then regroup tens and hundreds when a place needs it.
Add and Subtract Word Problems (Within 1,000): worked example

Add and Subtract Word Problems (Within 1,000): how to help at home or in class
Draw a bar model: a long rectangle for the whole, split into two parts, with a question mark over the unknown. Your child fills in the story numbers and decides whether to add or subtract. Estimate first by rounding each number to the nearest hundred, which helps catch slips. When they solve a story and can also check it with the opposite operation, they are ready for two-step stories.
