Canter Exercises please

[kate081]

A has had a couple of weeks off schooling after having a wolf tooth out & is feeling quite fresh! In canter she wont settle until she's let off steam. That's fine at home but we're off to dressage on Sat so I need some exercises that will:
1) get her to engage her brain & come rounder
2) stop her rushing

All suggestions appreciated.
Thanks!

Plenty of circles, varying size. Transitions and changes of rein.

Counter canter and leg yielding. Transitions - especially canter/walk/canter.
