There are several resources for drills and practice plans. In general, try to break the team up into smaller groups and keep them moving between stations. Recruit other parents to help with drills.
Youtube is your friend, just google "fastpitch softball drills"

General practice plan
A. Warm-up and stretching (10 minutes)
B. Throwing drills (15 minutes)
- work on age appropriate level Ball in the correct position, chin is the target, two hand catch, feet in position, step into throw
- Do some type of competitive drill the last 2 or 3 minutes most catches or do criss cross drill and count number of drops or how much time it takes or how many balls they can get through compare to previous drills to note improvement.
C. Defensive Drills – use multiple stations to keep more kids involved (no standing around)
- Ground balls, pop-ups, around the world, follow the throw, etc
D. Base Running/sliding – Teach 3 step lead, watch the hit, when to pick up 3rd base coach, tagging up on Fly ball, delayed steal, sliding (hook, straight in, slide by tap)
E. Hitting – use 2 or 3 stations to keep everyone involved lots of tee work should try to get 100 swings by each player (single tee, double tee, soft toss, pitching machine or coach toss)
- stress hip rotation, arms in, shoulders level. Watch for bat casting, stepping in the bucket or happy feet (stress getting ready loading and being still before the pitch arrives, positive attitude toward hitting think yes, yes, yes until pitch tells you no.)
- Bunting, all the girls that attended Firebirds Camp in January learned to bunt!
F. Conditioning (10 minutes) Make it fun relay races around the bases, play pickle kids love a contest.
This will cover a one and a half hour practice and kids should be active and not standing around.
