Hundreds Chart Activities: 20+ Games and Ideas for K–3 Math

Why Use a Hundreds Chart?

Each row holds ten numbers, so the chart is organized the same way our number system is. Once students notice that, a lot of math falls into place:

• Patterns. Every number in a column ends in the same digit, and the tens digit goes up by one in each row.
• Place value. Moving down a row adds a ten; moving across adds a one. Students start to see 47 as four tens and seven ones.
• Ten more and ten less. The number just below is always ten more, and the number just above is ten less — no counting needed.
• Mental math. Jumping around the chart builds strategies for adding and subtracting two-digit numbers.

Daily Hundreds Chart Routines

A few minutes with the chart every day goes a long way. These routines fit into calendar time or a math warm-up.

1. Number of the day. Pick a number and have students find it on the chart, say it, name the numbers before and after it, tell whether it is odd or even, and find ten more and ten less.
2. Counting the days of school. Color one square each day you are in school. Count the colored squares together, then count by tens to the last full row. The chart fills up just in time for the 100th day celebration.
3. Choral count with a pointer. Point to numbers as the class counts forward or backward. Start at a number other than 1, like 38, so students practice counting on.
4. Quick find. Call out a number and have a student point to it fast. Ask how they found it — many will say they looked at the tens first.

Skip Counting Patterns: 2s, 5s, 10s, Evens and Odds

Coloring skip counting patterns is the classic hundreds chart activity. Counting by 2s makes stripes, counting by 5s fills two columns, and counting by 10s fills the last column.

1. Predict, then color. Before coloring the 5s, ask students to predict which squares will be colored. Then color them and check.
2. Two patterns, one chart. Color the 2s in one color and the 5s in another. Which squares got both colors? What do those numbers have in common?
3. Evens and odds. Color all the even numbers and ask what students notice about the columns. Then talk about why every other column is even.
4. Start somewhere new. Count by 10s starting at 3. Students discover that the numbers 3, 13, 23 and 33 run straight down one column.

Skip counting by 2s, 5s and 10s leads naturally into early multiplication. See building multiplication fact fluency for what comes next.

Missing Number and “What’s Covered?” Games

Hiding numbers turns the chart into a puzzle. To find a covered number, students think about what comes before and after it and what sits above and below it.

1. What’s covered? Hide a handful of squares while students close their eyes. They name each missing number and explain how they know.
2. Cover a pattern. Hide all the 10s or all the 5s, then have students say the covered numbers in order.
3. Partner cover. With a printed chart and a few small counters, one partner covers squares while the other looks away, then they switch.
4. Hundreds chart puzzles. Cut a printed chart into a few large pieces and have students put it back together.

Ten More, Ten Less, One More, One Less

These four moves are the heart of the hundreds chart. Teach them as directions: one more is a step right, one less is a step left, ten more is a step down and ten less is a step up.

1. Arrow cards. Show a starting number and a card with one or two arrows. Students follow the arrows and name where they land.
2. Simon says moves. “Start at 52. Ten more. One less. Ten more.” Students trace the path with a finger.
3. End of the row. One more than 30 isn’t to the right — it wraps to the start of the next row. Practice these tricky spots directly.
4. Human hundreds chart. Give each student a number card; they find their “ten more” and “ten less” classmates.

Addition and Subtraction Jumps

Once students are comfortable with ten more and one more, they can add and subtract by combining moves. To solve 34 + 23, start at 34, jump down two rows to 54, then step right three squares to 57.

1. Tens first. Add the tens by moving down, then the ones by moving right. Students color the start and end squares to record the jump.
2. Subtract by going up. For 68 − 25, move up two rows and left five squares.
3. Find the difference. Color two numbers and ask how far apart they are. Students count rows and squares to find out.
4. Make 100. Pick a starting number and ask how much more is needed to reach 100.

Mystery Number Riddles

Riddles get students reading the chart for clues. Start with two clues and add more as students get stronger.

1. Clue riddles. “My number is ten more than 25. It is odd. What is it?” Students use the chart to check each clue.
2. Guess my number. Pick a secret number. Students ask yes-or-no questions like “Is it more than 50?” and “Is it in the 5s column?” and cross out numbers on a printed chart as they go.
3. Write your own. Students write a riddle for a partner to solve.

To choose who reads a riddle, try a fair way to call on students.

The 1–120 Chart, Printables and Differentiation

Using a 1–120 chart in first grade

Many first-grade standards ask students to count, read and write numbers to 120. A 1–120 chart adds two rows, so students see 101, 102 and 103 fall in the same columns as 1, 2 and 3. Try covering numbers in the last two rows.

Printable practice

Differentiating hundreds chart activities

• Start small. Kindergartners can work with just the first few rows, covering one number at a time.
• Adjust the challenge. Cover a few squares in a row for beginners, or many scattered squares for students who are ready.
• Try the 0–99 chart. Each row starts with a multiple of ten, so every number in a row shares its tens digit.
• Stretch strong students. Count by 3s or 4s, start skip counting at an unusual number, or solve riddles with three or four clues.
