HOT TIP. Supply Teaching is Great!

     You only need about 20 or so really smart, snappy, outcome driven lessons to get you through a week of relief teaching.

     It would be a good idea to keep on refining these lessons until you can apply them to any class and any school. 
     Keep a couple refined so that they are the sharpest in your repertoire.
     It's great to have that level of confidence behind you so that your authority as a teacher shines through.
