Probably below average to average athleticism.
They bought their own new skates, but they are like $50 cheep pairs
Okay. Sounds like public skating sessions so there are basic rules with regimentation to follow.
Seems like the intro stages have been covered. A few practical considerations.
Basics. Even inexpensive skates have to be cared for. Explain that they should check the blades before and after for damage,sharpening if necessary, use skate guards to walk to the rink from the room, proper safety gear as required(helmet a must), comfortable, light off ice warm-up - stretching, movement, flexibility.
Overlooked when teaching first time skaters is the actual stepping on the ice. Some rush, lose their balance and take a nasty fall. Nice comfortable, controlled entry on their power leg. Warm-up skating at their comfort level until they relax the rigidity and uncertainty of getting back on the ice. As they get comfortable their arm and body movements will become more fluid. Have them repeat their strengths while working on their weaknesses. If stopping is weak, don't just work on stopping. Do it in the context of overall skating.
Fatigue. Even if the new skaters are in shape, fatigue is a factor since they are not used to using their muscles to skate. Tired skaters tend to reduce arm movement, become less fluid. Risk of falling and injury increases.
Repeat the basic movements to both sides, LHS, RHS. Clockwise, counter-clockwise as permitted at the rink.
Good luck.
