Conversation Hearts Sticker Activity

What teacher doesn't love the $1-$3 section at Target?  I'm always finding great stuff to use as manipulatives over there.

Recently, I found this pack of 100 ct. Conversation Heart Stickers for $1.  In addition to the sayings in the picture, there are two others: a green 'text me' and a white 'too fun'.  The stickers are foam and easy to use.  Also, all the sayings are appropriate (there's no 'sexy' heart).

I'm thinking the 3rd graders might have fun with these and use them to create B-A-G melodies.  First, they'll stick the stickers at the bottom of a page (lyrics), then add stick notation (quarter notes or eighth note pairs), then solfa pitches (G is Do, A is Re, and B is Mi), and finally draw this on the staff.  They can sing and play these melodies and share them with friends.
