The two dance troupes both progressed in the competition after triumphing in the public vote over fellow hopefuls Hippy Joe, The Future, Rikoshay and Lloyd and Rebecca.
After opening the semi-final, The A Team were praised by judges Ashley Banjo, Kimberly Wyatt and Adam Garcia as being "amazing" and "as close to perfection as you can possibly get", with Garcia adding: "The words 'jaw dropping' don't encapsulate what I saw. I didn't dare blink. You've got to be in the final."
Southend crew Methods of Movement also wowed the panel, with former Pussycat Doll Wyatt remarking: "I have goosebumps! So exciting and entertaining, you take risks and I have mad respect for that. You are entertainment and it's gold."
The A Team and Methods of Movement will join Prodijig, Tayluer & Elliott, Boadicea, Fear of the Unknown, Sweet Surprise and Antics in the series final, which will be shown live from London's Olympia on March 4.
The remaining semi-final will take place next Sunday (February 26) at 6pm on Sky1.
