When it comes to Valentine's Day, I hesitate to give my students the boxed cards....you make my heart flutter? I only have eyes for you? Yeah, just not appropriate! But, I have yet to find a decent set of Valentine's Day cards on the internet with graphics that I just love to print out for my 4th graders. So many have chemistry puns that, while I find them quite amusing, will fly over my kids' heads. They're only in 4th grade!
So, I created some cards for teachers to give their upper elementary students. The first set is science-related, but the kids will understand them. The second set contains coupons for extra credit! Who wouldn't love that?? (Both sets are in the same document on Teachers Pay Teachers.)
