We could do this with out Frida Kahlo self-portraits--make them "selfies"! Fun, contemporary back-to-school lesson! Have your students draw "selfies" and describe their summer via text message prompts. Makes for a great bulletin board display!
Each teacher picks their favorite book from the book fair and then students try to guess which teacher chose that particular book. Could also say "Come take a look at our favorite books!" if you have ordered bulletin board books.
