A hundreds board is a 10x10 board with cells displaying the numbers 1-100. Some hundred boards display the numbers 0-99 instead, and some include more than 100 numbers. Hundreds boards are powerful manipulatives for students to visualize the base-ten structure of our number system because each number is one more(less) than the number to its left(right), and ten more(less) than any number above(below) it.
Includes features that are difficult or impossible to do with physical manipulatives. Single numbers can be highlighted with a simple tap, and multiple numbers can be selected with an easy swipe. All multiples can be automatically highlighted, making it easy to explore multiples and least common multiples. A "rounding" mode uses a tilted hundreds board so that users can place a ring on a number and see that ring slide to its rounded value. A specialized mode models addition by showing that the ones place of the second operator indicate how many places to move horizontally and the tens place of the second operator indicate how many places to move vertically.
