Valentine's Day is close, very close. My daughter decided that this year she wanted Doctor Who Valentines to hand out in class. We designed a simple printable card that says: "Fezzes are Red. The Tardis is Blue. Bow Ties are cool and so are you."
I'm not sure how the other Kindergartners will receive these. My kid doesn't care, saying "It's not my fault they don't know the Doctor."
We are pairing the cards up with (candy) Fish Fingers and Custard.
If you want to grab the printable you can get it here Download DoctorWho, it's a PDF file with 4 on a page. I recommend that you print them on card stock.
