Prove counting ability up to one hundred

Mastery of the first hundred numbers is a significant prerequisite to beginning addition. We think there is no better way to establish this mastery than with an old-fashioned hundred chart. The student fills in each of the squares in the grid to reinforce the sequence in both the tens and ones place. For those who are not ready for this yet, you can have a percentage of the chart pre-filled for them.

This hundred chart has one unusual option - you can select from more than just Arabic base 10. For instance, a Roman hundred chart is a good way to provide practice in Roman numbers for older students, and three other digitally common number systems can be used in computer science. We may add more number systems to this worksheet in the future.
