We use sound and spelling cards, with pictures, in the classroom to help students relate sounds, letters, and spellings. The picture for the letter "b" is butterfly.
The week I introduced this sound, we were using a Justin Bieber song for clean-up. One little buddy
said, "Hey, Bieber is just like butterfly." The next day in our phonics lesson,
the same buddy said he was no longer calling it the butterfly card, but the Bieber card. I agreed, and between the two of us we have the whole class using "Bieber" instead of butterfly. Of course we had to put a picture of him on the card. Later, I sneaked into some other classrooms and put Bieber pictures on their butterfly cards.
