After all this preparation it is time to start implementing the first of your new approaches. Introduce only one new measure at a time, make sure the class is well prepared, and be ready for early setbacks. Not everything will work as you expect, but there will be a reason for that.
Watch the pupils’ reactions (or ask them) and see what tweaks may be needed to make things work better. Give each new measure time to bed down before starting the next.
