Just remember, the most valuable aspects of WBT are the student engagement, the engagement of the whole brain, and the fun.
Keep your students engaged through gestures (Mirror!), through the scoreboard (Mighty Cheer! Mighty Groan!) and Teach-Okay! Those three things will make your lesson stellar.
Also, if you don't already do this, between now and then practice NOT asking for raised hands to answer questions, but simply posing a question to the whole class and choosing a student to answer (either at random, or because you are matching the question level to student ability). Use the "It's cool!" if they aren't able to give a correct answer, and the "Woo!" if they are.
