I graduated last year
It was great to see what the kids brought with them to 4th. When we got to things and they acted clueless, it was easy for me to say "I KNOW you did this last year..." Kind of eye opening!
Remember, these are the kids you had at the end of the year last year - they are ready to go right where you left off!
I looped with my group, so I actually started from scratch with BTS things, but this year, since it will be a new group, I plan on going back to all the things I did in 3rd grade at the beginning of the year.
There is one new thing I added this year, and plan to do every year, as it was very insightful. I am attaching a reading survey I gave the kids the first day of school. I piloted it on my group last year, and this year it will be helpful in getting their book buckets set up for them.
