Hi there!
It sounds like the first few weeks haven't gone as smoothly as planned, but fret not! Keep consistent with WBT. Liann has some great suggestions for you! I simply wanted to add that with 29 5-year olds, you want to keep them entertained as well. Remember, teaching is performing! The sillier and goofier you "Class! Yes!" the more motivated and fun the students will have responding back. Add in claps, stomps or snaps, hip wiggles, funny voices, turn arounds--anything to get their eyes and focus on you, and to get them moving a little bit!
I might even spend some time going back over what it looks like and what it doesn't look like (let them act out EXACTLY what you don't want first, then MODEL and PRACTICE exactly what you do, several times.
Liann's tip of breaking the day into small rewards after activities and lessons is great! Especially for the younger ones, since one school day can seem like a lifetime to them. This will also give them plenty of time to practice and learn.
I hope this helps. Keep us posted on how things are going and we can brainstorm more ideas and tips for you!
Happy Teaching!
