This year we all created a 100th day of Second Grade page and illustrated what we thought we'd look like in 100 months (age 16) and then when we are 100 years old!
These are 100th Day glasses we used on the 100th day in 2007, you can order them from ReallyGoodStuff
We read Emily's First 100 Days of School during morning meeting during the first 100 days of school. We actually ended up reading the book about every 5 to 10 days to keep the students interested and to have enough events to share.
