Hundred’s Day is a big deal in our class. Isn’t it great that we can turn a number into a cause for celebration?
It’s such great review, and students are completely engaged and excited to show their skills. For this reason, we usually end up extending the fun into Hundred’s WEEK! There’s just too much learning to pack into one day.
How Do We Celebrate?
We review counting to 100 by making giant collaborative hundred’s charts together.
This so great for teamwork, and it is great assessment for me!
*Hint: If students are using felt pens to alternate colors (for odd/even), have some white squares to glue over top of any mistakes so they don’t have to start all over again!
Hundred’s Chart Strategy Games
We use our Hundred’s Chart to play a number of different “games”.
Here are a few:

100 Cats Poster
Here’s a poster we made together to celebrate hundreds day!
It’s called “100 Cats and 1 Mouse”.
To make it, each student drew 3 or 4 different cats to glue onto a blank poster. Then, I made one tiny mouse to hide amongst the cats (while students were out for lunch). When they came back, they had so much fun searching for the mouse, and then inviting anyone who walked by the class to find the mouse, too.
We eventually put it out in the hallway so we could listen to people talking about it. You can grab a free template to make this poster with your students HERE. Enjoy!
No Prep 100’s Day Printables
Maybe you prefer to make your own workbooks? No problem – I have a whole set of clip art to help with that! Just drag the images into your document, add text, and print! That way you can make it the way you like!
If you need more work with the 100’s Chart and Math Sense in general, you can grab this set which focuses on number sense for Grade One. It also includes printable centers and differentiated workbook pages to meet the needs of a varied classroom.

Thank you for the sample and freebie of the cat and mouse. I started following you from the 2nd grade fb group. This is my 1st year teaching so ideas and freebies are so important to me. I can’t wait to do this…tomorrow is our 100th day..but I may need the whole week to do all the awesome learning activities I have found. Thanks again!
I downloaded your cat and mouse activity a couple of weeks ago because I KNOW my students will love it! They’re obsessed with I Spy books! Thanks for linking up. Hope you’re enjoying your weekend!

Mrs. Beattie’s Classroom
We are gearing up towards our 100th day (my favorite “holiday”!) and we started our 100 cats poster today. I just had to tell that the kids (K) had a BLAST! They thought it was THE funnest thing to do: pick a cat, color it in funky colors, cut it out and then go stick it on the small bulletin board just outside our door! Sticking them upside down was even better! 😉 We made 60 today and will finish up tomorrow. Not only was it fun, but they really got a feel for how large of a number 100 is! I know they’ll keep looking and talking about our collaborative poster for a long time! 😉 Thanks so much!! I really appreciate it! 🙂
(I think I’ll have to use sticky tack for my mouse so I can move it around and keep them guessing for a while! 😉
