📝 This post, Number Lines, was originally published in 2013 and has been updated with new information and resources.

When I first started teaching first grade, I quickly realized something surprising. Even though many of my students had seen a number line before, they didn’t always know how to use one correctly. The biggest challenge? They wanted to start counting on the number they were already on instead of moving to the next number.

That’s what inspired me to create The Number Line Hop. What started as a simple classroom game has become one of my most effective back-to-school activities for teaching students how to use a number line correctly while building number sense, counting skills, and confidence. Best of all, my students loved it so much they never realized how much they were learning!

Why Teach Number Lines?

Number lines are one of the most valuable math tools we can give young learners because they help students understand how numbers are connected. Instead of simply memorizing facts, students begin to see that adding means moving forward, subtracting means moving backward, and every number has a specific place.

As students become comfortable using a number line, it also supports counting on, counting back, comparing numbers, finding one more and one less, and eventually skip counting and place value. The stronger a child’s understanding of a number line, the easier many other math concepts become.

The Number Line Hop

The first version of this game was nothing more than a row of blank squares. Before we ever started playing, my students created their own number line from 0 to 15. Building the number line together helped them understand how it worked while also giving them ownership of the game board. It also gave me a quick way to assess their number writing and counting skills.

Before we rolled the dice, we spent time talking about the correct way to use a number line. The biggest lesson was learning that you always start counting at the next number—not the one you’re already standing on. This is a very common mistake for first graders, and it’s exactly why the game uses a frog as the playing piece. Frogs jump forward—they never land on the lily pad they’re already sitting on!

Before we ever played, we stood up and pretended to be frogs. We practiced hopping to the next number and calling it out together. That little bit of movement made all the difference. Once students understood how frogs hopped, using a number line correctly suddenly made much more sense.

How to Play

Players move their frog along the number line by rolling a die and an addition or subtraction marker, hopping forward or backward the correct number of spaces. There isn’t a winner or loser—the goal is simply to give students lots of practice using a number line correctly while having fun.

More Ways to Practice with Number Lines

Once students understand how a number line works, there are so many ways to keep practicing. Here are some of our favorites.

Learning the Number Line

Which Number Is It? Say a number aloud and have your child place a bean or chip on that spot. Then have them call out a number for you to find.

Cover a Number: Use a sticky note to cover one or two numbers on the line, then have your child figure out what’s hidden underneath by counting from zero.

Number Match: Grab number cards, place them face down, and have your child draw a card and match it to the correct spot on the number line.

Building Number Sense

Greater Than/Less Than: Talk through how numbers get bigger moving right and smaller moving left, then pose questions like, “Which number is bigger, 6 or 2?” Have your child place counters on each number to compare.

What Comes Next? What Came Before? Have your child draw a number card, count to that number on the line, then name what comes just before and just after.

One More, One Less: Roll a die once to get started on the number line, then set the die aside. From there, draw cards that say +1 or –1 and move accordingly—a great way to reinforce one more and one less. For an extra challenge, use larger numbers like +3 and –3, or have students write the matching number sentence.

Addition and Subtraction

Addition/Subtraction Number Line Game: Using a number line that goes to at least 20, players roll a die and hop that many spaces, recording the number they land on. Roll again, hop forward or backward depending on the operation, and record the answer. The next player’s turn begins where the previous player ended.

Complete the Pattern: Great for skip-counting practice! Create a number pattern (such as 2, 4, 6, 8), remove one number, and challenge students to use the number line to determine the missing number.

Wrapping Up

I’ve learned over the years that simply handing students a number line isn’t enough. Taking the time to teach them how to use it makes all the difference. Once that understanding clicks, a number line becomes one of the most powerful tools in their math toolkit.

I hope these games, activities, and printables help your students build confidence and make using a number line feel as natural as counting.
