2. STEM Activities for the 100th Day of School

Use building blocks to review math concepts? Check! Challenge your students to create a structure using exactly 100 Legos, and review a few math concepts while you're at it. It's more challenging than you might think.

Combine geography and opinion writing when you ask your students to determine tourist destinations 100 miles away from your town.  Then have your students create a writing piece, script, or commercial to persuade others to visit their destinations.

100 days may go by quickly, but 100 years can sure see a lot of changes. Your students can research inventions from 100 years ago, converse on what they look like in the present, and hypothesize what the same invention will look like 100 years in the future.
