Iain, not sure if you mean place kicking or drop/punt from hand. For punting and drop kicks I would run through the mechanics, how to hold the ball, how to kick (i.e imagine a tennis ball in the middle, etc). Then put them into pairs and have them gently kick to each with the intention being that the reciever must catch it for the pair to score a point. I would start over a short distance (say 5m) and then increase the distance as they get better and also encourage kicks with both feet. A fun drill we perform with our junior colts is a kicking game scored like tennis with every player taking a turn to kick. The kicking side scores if the ball stays in play, is catchable (e.g. not 12 inches off the ground!) and is not legally caught. The catching team scores if they catch the ball. The pitch/court is laid out with cones with the size varying depending on the number of players. Another drill is to place a cone as a target and each player has 3 goes to see who can get the closest. Vary the placement to mirror what you are looking for in a game. As for place kicks, they have no doubt been trying to do this from their first day!! I'd simply have a kicking competition sometime during each training session. Start in front of the posts, say 10m out, then move to the sides, then a bit further back until you have a winner. From this you can see those who can kick and you can then work with them more intensively. Good luck.
