Grades K to 3
Hundreds Chart
Color squares to find patterns, light up skip counting by any number, or hide numbers for a fill-in game. Tap, drag across squares, and print.
Tap a square to color it, or drag across several. Hide and reveal turns a tap into show or hide.
Ways to use it in class
- Skip counting. Count by 2, 5 or 10 and look at the shape: twos make stripes, fives make two columns, tens make one.
- Adding ten. Start on any number and move one square down: the tens digit grows by one and the ones digit stays.
- Odd and even. Color every even number and the chart splits into alternating columns.
- Missing numbers. Hide all, reveal a few, and ask what goes in the blank squares around them.
- Mystery picture. Read out numbers for students to color, and a picture appears.
Printing a hundreds chart
Press Print for a full chart, or hide numbers first for a fill-in worksheet. Colored squares print in color, so a pattern you made on the board can go home with students.
Questions teachers ask
- What is a hundreds chart?
- A ten-by-ten grid of the numbers 1 to 100, ten in each row. Moving right adds one and moving down adds ten, which is why it is one of the first pictures of place value children meet.
- How do you skip count on a hundreds chart?
- Type the number to count by, for example 5, and press Show multiples. Every fifth square lights up and the pattern of the five times table appears: two straight columns.
- What is the difference between a hundreds chart and a hundred chart?
- Nothing: both names are used for the same grid. Some classes prefer the 0 to 99 version, which puts every number with the same tens digit in one row; choose it above.
- How do I make a missing-numbers worksheet?
- Press Hide all, then switch to Hide and reveal and tap the squares you want students to see. Print the chart, and students fill in the blanks.
- Why go up to 120?
- Many first-grade standards ask children to count to 120, so the 1 to 120 chart adds two more rows past 100.
