Give your students extra practice with addition and subtraction word problems! This third grade-level math lesson will help children become more confident and proficient at solving word problems. By the time students are finished working through this lesson, they will be skilled at solving a variety of addition word problems and subtraction word problems.

Students will determine whether they need to add or subtract the numbers presented in their word problems. Here is an example of questions children may be asked in this third grade math activity: "There were 55 people on the subway heading uptown. At the 42nd street stop, 13 more people got on. How many people are on the subway now?" Another example, "61 people signed up for the pottery class at the City Recreation Center. 59 people showed up to class. How many people missed the class?" A third example, "There were 88 cars on the lot at the North Avenue Car Dealership. Last month, 55 of them were sold. How many cars are left?" Word problems include addition questions and subtraction questions.

If students need a little extra help, they can click on the "Hint" button to be shown a relevant written or pictorial clue. For example, in the last example above, the hint would say: "Subtract to find out how many cars are left." When students answer a question incorrectly, a detailed explanation page shows them exactly where they went wrong, so they can learn from their mistakes as they move through the lesson.
