Use these 100 Ideas for Items to Use to Count to 100 with estimation jar ideas and 100th day of school activities!
Many kids around the country are celebrating their 100th day of school this month and we are having some math fun along with them!
Teaching kids to count to 100 is a big milestone and one that parents and teachers work on for a few years.
It's a long journey fraught with numbers like "fifteen-ten" and other assorted creative ways to count.
And along the way, kids are also learning to count by 2's, 5's, 10's and categorize numeric values.
100 Things Kids Can Count: Ideas for Estimation Jars & 100th Day of School Activities
For a number of years, I remember my kids coming home with a note asking that each child in the class bring in "100 of their favorite item" to celebrate the 100th day of school.
100 of their favorite item -- whew! Now those were some long discussions --
Kid: "How about 100 stuffed animals Mom?"
Me: How about we think of something a little smaller?
Kid: "I want to bring in something that the other kids won't bring."
Me: Ok, how about crayons?
And so it went for about 50 more suggestions until we finally came up with a winner!
And in the process, we also came up with quite a list of possiblities in case you're having trouble thinking of small items for your 100th Day of School celebration or fun things to put in an estimation jar!
There are some super fun ways to help kids practice all this counting.
One popular idea is to introduce a 100's Jar. Similar to an estimation jar in many classrooms, a 100's Jar holds one-hundred pieces of the same item.
If you use plastic bottles or jars, you can introduce a number of math concepts such as volume, size and weight. So the first part of our list includes lots of items that can be counted, sorted, categorized and compared.
I had some extra mason jars that we used to do some counting and comparison. Just make sure that the jar or bottle you use is transparent so the kids can see & explore the items inside it. I've also tried to make life easier for you by including affiliate links to items we've used, those that may not be well-known or might be hard to find.
Now if my youngest had HER way, she would bring 100 books to school to celebrate (and read them all too :)
Can you imagine stacking 100 of your favorite stories??! That would actually be pretty cool to do.
Here are a few books that would be perfect for this math day celebration:
The Night Before the 100th Day of School -- the students are all thinking hard about what to bring the next day!
100th Day Worries - Jessica want's to bring something AMAZING to school for the 100th day but has a hard time deciding just what that should be.
Rocket's 100th Day of School (Step Into Reading, Step 1) - perfect for beginning readers.
Emily's First 100 Days of School - my daughter and I just LOVED this book! It's a huge learning resource covering numbers, letters and so many of the things that kids learn during those first few months of school. A must read (and a longer book that can be shared over a number of story time sessions).
