Tea Jar – Fill a canister with tea and then print this label from www.lifecreated.com
Personalized Heart Poem – I asked my child what they love about their teacher, typed in his reply on this link , and it generates a heart shaped card. Print and give. You can never go wrong with a child’s sweet words.

Gift Card – “A teacher can’t survive on apples alone…” – I saw this months ago as a Christmas gift but think it’d be just as cute for a year end gift.
Cake Pop Stand – after packaging each cake pop in plastic bags from Michaels, we wrapped a styrofoam rectangle in wrapping paper, stuck them in, and made a sign. Great Grab and Go treat when lots of teachers are involved.
