Fun first day activity: Have kids write a letter to themselves at the beginning of the year, to be time-capsuled and read at the end of the school year.
Word work idea: Play tic tac toe with spelling words. to play, students have to repeatedly write the sight word. fun way to practice!

Simple DIY chair for celebrating birthdays in the classroom! My students couldn't WAIT to sit in it on their birthday!
Adapt to learn about the students likes/background. Do one place they went, one person they spent time with, and an experience.
