#### Addition | Hundred Chart | Rounding | Skip Counting | Subtraction

Hundred charts are very versatile tools in the elementary classroom. Working with the patterns on hundred charts helps students develop place value understanding. Hundred charts are also excellent tools for solving multi-digit addition and subtraction problems. There has also been a lot of buzz lately about flipping the hundred chart. Now, while I keep saying hundred chart, it’s more common for classrooms to feature 120 charts because of updated standards designed to emphasize the fact that patterns on the hundred chart extend to 3-digit numbers. But now you can extend it all the way to 1,200 with these personal 1,200 charts!

The personal 1,200 charts are created by gluing together smaller charts, as shown below. Each chart has a little tab at the top so students can glue them together into one long strip. Fold them up, like an accordion. The charts are arranged on the printable pages (which you can download below) so each page can be printed on a different color paper.

Now that you’ve got them, what can you do with the personal 1,200 charts?

• They are great for helping older students develop number sense. They can explore patterns on the hundred chart (10 more/10 less and 1 more/1 less) with larger numbers, thereby strengthening their understanding of place value.
• Practice skip-counting off the decade with larger numbers (585, 595, 605, 615, etc.).
• Use the charts for rounding to the nearest ten or hundred. For example, if trying to round 658 to the nearest 10, they can easily see that 655 is in the middle between 650 and 660 and that 658 is closer to 660. Likewise, if rounding 658 to the nearest hundred, they can easily see that 650 is in the middle between 600 and 700 and that 658 is closer to 700.
• Add or subtract multi-digit numbers through 1,200.

1. Thank you for the freebie! I teach first grade and have students with varying math competencies. This will be very helpful.

• Love that it meets a need for you, Kim!

2. This is exactly the visual my students needed last week as we started our 3 digit numeracy to 1000, thank you!! Timing is oh so perfect!!

• It’s perfect, right? My kiddos made theirs today!

3. Thank you so much! We did this about a month ago with normal size 100 charts. We went from 1-1000. We colored in counting by 5’s and 10’s and odds and evens. They are huge. It was a great learning actiivity because my second graders were really struggling with concepts like 10 more than 195. I am going to have them make the mini one’s because I think there are so many valuable skills they can practice and learn. Thanks so much!!!

4. Love this! I can use this for all sorts of activities with my kiddos. I’m going to use this next week for rounding practice with bingo chips with my 3rd graders and use it for number identification with my first graders as well. So many uses. Thanks for the great freebie!

• Perfect for rounding, Heather!!

5. Do you have specific activities to could share that you use this,cool tool?

• Any activities that you would normally do with a hundred chart, Dalia. This just extends it to larger numbers.
