Help!

I desperately need activity ideas for 2-3 year olds. I've been given 2 lessons a week with nursery children and I have NO idea what to do with them. I can't do crafts, it will literaly just have to be songs and simple games. I really don't know why they've given me nursery lessons because they don't do English yet. Well I do know why it's because my timetable was empty but nursery?! Ms. Cat said to read stories to them...which I'm thinking is just more than a bit pointless since they understand less than the K1s and have a 3 min attention span. Soo any ideas please, please email me!
