Students get to practice the principles of addition on this number line worksheet that features fun characters like ballerinas, frogs, skateboarders, and more.

Each page includes multiple number lines outlined in a square so students can see each problem easily. The number lines are accompanied by an addition problem and arrows. Kindergarten pages show the counting-on approach with +1 and +2. For example, the arrow on one number line shows a ballerina leaping from 3 to 4 with the math problem 3 + 1. Students can see that the ending number is 4, so they write it on the line.

First-grade pages feature addition up to +4. Number lines still show starting numbers, ending numbers, and arrows on the number line, but the math problem is only shown below. They count out the addition problem and write the answer on the line.

Each page clearly states which numbers are being added so you can differentiate instruction. For example, you can choose the +1 +2 page for early learners. Students who need a bigger challenge can complete the +3 +4 pages. These pages include number lines up to 20, with some answers and addends above 10.

Very young students can tackle beginning addition concepts when given a number line. It helps them see an addition problem as a counting problem, enabling them to connect the two concepts so they can tackle more complex addition problems later.

When students are brand-new to addition, you should give them a number line that shows the addition problem in action. For example, for the addition problem 3 + 2, the number line should show lines from 3 to 4 and 4 to 5, showing each addition problem as 3 + 1 and 3 + 2. They can see the final answer and understand how they got it.

Early learners should start by adding just 1 and 2. As students become more proficient, they can add 3, 4, and more. They can draw the lines on the number line to show their work and list the corresponding addition problems themselves. For example, for 3 + 3, they could draw the lines between 3, 4, 5, and 6, then write 3 + 1, 3 + 2, and 3 + 3 above the number line before writing the answer.
