Build number sequence fluency
Adjacent numbers differ by 1 across a row, supporting before-and-after numbers and counting in sequence.
Elementary math · Number patterns to 100
See how numbers connect on a hundreds chart
Start with a complete number chart from 1 to 100, then use missing-number practice to understand horizontal, vertical, and neighboring number patterns. Designed for short, focused practice beyond the classroom.
- Practice from 1 to 100
- Immediate answer feedback
- Made for phones and tablets
Practice focus
A clear 10×10 grid makes number relationships visible
A hundreds chart is more than a counting list. Position, rows, columns, and missing cells help children build an intuitive model of our base-ten number system.
Understand groups of ten
Numbers differ by 10 down a column, making changes in the tens place easy to see.
Reason through missing numbers
Children infer empty cells from a known number, practicing observation, logic, and addition or subtraction within 100.
Inside a practice session
Clear feedback, one question at a time
Children often need room to notice a pattern, try an answer, and make a correction without feeling rushed.
Random questions
Changing number combinations build familiarity with the pattern, not a memorized answer.
Mistakes stay visible
An incorrect cell is marked right away, leaving time to look again and self-correct.
Keep the rhythm
Previous, Clear, and Next controls keep each short practice session easy to follow.
Complete number chart
Hundreds chart from 1 to 100
A standard hundreds chart has 10 rows and 10 columns, with numbers in order from 1 through 100. The app shows a section of the chart with one number revealed, and learners fill the remaining cells.
- Easy, medium, and challenge levels covering numbers to 20, 40, and 100
- A fixed free question set, with randomized practice available in Premium
- Optional real-time error hints and a practice record for completed sessions
How it works
One practice session, three clear steps
Choose the right level
Begin with numbers to 20, then move to 40 and the complete 1–100 hundreds chart.
Study the given number
Locate its row and column, then use ±1 across and ±10 vertically to reason outward.
Fill the cells and review
Complete the missing numbers, check the result, and use practice records to revisit completed sessions.
Common questions
About hundreds chart practice
Is a hundreds chart the same as a 100 chart?
Usually, yes. Both commonly mean a 10×10 number chart containing 1 through 100. You may also see the terms hundred chart, number chart 1–100, or 100 number chart.
What ages are hundreds charts for?
Hundreds charts are widely used in kindergarten, first grade, and second grade. They are helpful when children are learning number sequence, place value, number sense, and addition or subtraction within 100.
How does practice work in the app?
Choose a difficulty and question count. The app shows part of a hundreds chart with one number revealed. The learner uses number patterns to fill the missing cells and then checks the result.
Can I view a complete printable-style hundreds chart?
Yes. The “What Is a Hundreds Chart?” page includes a complete 1–100 chart image and an explanation of its basic patterns. The same reference is available from the app’s Help page.
