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.

Educators, parents, and students alike enjoy using the "I Know It" math program alongside their elementary math curriculum for extra math practice.

Here are some additional lesson features that help students make the most of their math practice time. A progress-tracker in the upper-right corner of the practice screen allows students to see how many questions they have answered so far in the lessons, and a score-tracker beneath that shows them how many questions they have answered correctly. A speaker icon indicates the read-aloud feature; students can click it to have the question read to them in a clear voice. (What a great option for ESL/ELL students or for students who prefer auditory learning.)
