Addition with 3 or 4 Addends

Try this interactive math activity with your students to help them practice addition with three or four addends. In this math activity geared toward a fourth-grade level, students will practice adding with three or four addends to build confidence and proficiency with their addition skills. Questions in this online math game are presented as word problems, horizontal addition problems, and vertical addition problems. Children will fill in the blank with the correct answer.

Want to get a glimpse of the types of questions your students may be asked in this fourth-grade addition lesson? Here are a few examples: Students may be given a vertical addition problem with the following addends: 583 + 1,181 + 1,798 + 544. Or students may be given a horizontal addition problem instead: 8,907 + 192 + 7,279 + 659. Alternatively, students may be given an addition word problem like this one: "Liko and his friends spent Saturday afternoon playing games at Arcade Craze. Liko won 759 tickets, Abigail won 5,866 tickets, Kaitlyn won 300 tickets, and Wesley won 521 tickets. How many tickets did they win combined?" If students need a little extra help solving an addition problem, they can click on the "Hint" button. They will be given a helpful clue, such as "Step 1: Add the ones" or "Step 2: Add the tens." When students answer a question incorrectly, a detailed explanation page will show them how to solve the problem correctly, so they can move through the lesson having learned from past mistakes.
