Celebrating 100 days naturally lends itself to lots of different lessons in math. We read the book "One Hundred Hungry Ants" and demonstrated the different ways the ants lined up.
Another fun -- and yummy -- lesson dealt with popcorn. We counted out 100 popcorn kernels and then predicted how many would pop vs. how many would remain unpopped.
Once our predictions were made, we got out a hot air popper and watched the kernels pop!
One by one, we counted the popped pieces of popcorn. Once we got to, say, 40 we knew we could cross a couple of inaccurate predictions off the list. This was a great review of greater than/less than!
We ended up with 87 pieces of popped corn. We calculated how many away from 100 that was, and also calculated which student's prediction was closest.
Lest you assume 100 is all about math, we challenged our students to write 100 words! They were able to look around the room and write down 100 different words that they saw printed anywhere in the room. This activity, sometimes called "write the room," was a lot of fun!
