Well done
Sounds like a good start and they all offer various behaviours when they try to work it out, which I think is so cute. The temptation is to help them, but to be honest, the less you do and the more they suss it out for themselves the more likely they are to remember it. However, if she is struggling, try and help.
My little dog is doing her walk backwards for everything at the moment. If in doubt walk back, looks like moonwalking, makes me laugh and she knows it! I have just taught her to circle me, so may use this now to circle me backwards.
Whats next for you then?
