Regarding food and homemade 'goodies' for teachers at any grade level.
You don't know the likes/dislikes of the teachers.
You don't know of any food or nut allergies of the teachers and/or their families.
Do you know if the teacher is on a special diet....diabetic, watching cholesterol, etc. etc.
In some cases even the best tasting, well meaning item might get discarded in the trash. The teacher would NEVER tell you that....just say your food was fantastic!

Just like we were taught to do .....
Even a small gift card of $5 is better IMHO than any food item.
Same goes for scents, candles, body lotions, teacher themed items, body soaps, Christmas ornaments, mugs, bags, etc. etc. Teachers have a ton of that.
In these days probably the best is classroom supplies or a small gift card. I sub and can tell you I see cabinets stuffed full of mugs, teacher themed items and body lotions that are just sitting there (of course NOT where the kids can see). The food that one child brings in for the teacher usually finds its way to the staff lounge so everyone can try....and at holiday time the tables are 'overflowing' and not all gets eaten.
I am sorry if I offend anyone but really, really think before doing the homemade goodies. IF the teacher is a great, fantastic personal friend then go for it. But if not go for even a nominal amount gift card!
