This year we are celebrating with STEM Challenges and using an engineering design notebook to document our process. We'll be building a desk that holds 100 papers.
And a tent that uses "poles" made of 100 Cheerios
Here's another great find. It's a cute and very catchy video counting to 100. Click the image to watch.
Still need more ideas? Here's a link to a FREEBIE

Whatever you do to celebrate have fun!
