At our school the younger graders celebrated the 100th day of school. It is a great opportunity for us as teachers to hone in on the number 100 and its place value. It also allows for everyone to have a fun time with items/games/activities associated with the number 100.
This year was a bit different from all of the other years I have taught school. Yearly, students are asked to place 100 items of anything on a poster to celebrate the 100th day of school. When I walked around the corner I saw this:
Upon a closer look, I had to believe my eyes: Yep, those are bugs, dead cicadas to be exact.
No, I am not sure who made this poster, but I have to give the parents a pat on the back for being...so creative. :-) Shay and I can't wait to come up with 100 poster ideas!
