Interactive 100-chart
This interactive tool allows children to explore a 100-chart or a teacher to illustrate various math concepts, such as even and odd numbers, multiples of 5 and of 10, and skip-counting by 2, 3, 4, 5, and so on.
When you click on a number, it simply changes color. You can choose to have the chart empty, in which case clicking on a square reveals the number in it.
Besides a 100-chart, you can also make this number chart to show 20 or 1000 numbers.
