Geared toward third-grade students, this online math game will help children become confident and proficient at solving addition problems with four-digit addends. Try out this third-grade addition game with your class to help students expand their addition knowledge!

Students will solve a variety of multi-digit addition problems with regrouping in this interactive math practice game. Children will solve problems like these: "7,263 + 1,790 =" "6,813 + 2,008 =" and "6,582 + 3,417 =." Students may be asked to solve an addition word problem like this one: "Meg traveled 1,919 miles from Iowa to New York. Then she traveled 2,537 miles from New York to Nevada. How many miles did she travel in all?" If students need a little extra help solving an addition problem, they can click on the "Hint" button in the lower-left corner of their practice screen. They will be given a clue that will help them jump-start the problem, such as "Step 1: Add the ones and Step 2: Add the tens." When students answer a question incorrectly, a detailed explanation page pops up on the screen to walk them through the steps to solving the problem correctly. Students will progress through the math activity having learned from previous mistakes.

This third-grade addition lesson is equipped with built-in tools to help students make the most of their math practice session. A speaker icon in the upper-left corner of the practice screen indicates the read-aloud option. This button can be clicked if students want to hear the question read out-loud to them in a clear voice. This feature is an excellent resource for ESL/ELL students and children who are auditory processors. A progress-tracker in the upper-right corner of the practice screen shows students how many questions they have answered out of the total number of questions in the math lesson. A score-tracker beneath that lets students know how many points they have earned for correct answers so far. All of these handy tools are designed to help your students achieve success with the I Know It online math program.
