20 min Interview activity for nursery

[goingmad]

I have been shortlisted for a job as a TA in a nursery and have been asked to do a 20 min activity or game with a group of 4 nursery children to develop pupil learning.

I'm only part way through my level 3 STLS and am doing one day a wk voluntary work in a year 2 class. I have little exposure of nursery and am in shock that I have been selected! Now I'm panicking about the activity!

I'm not sure what my resources are if any and am looking for ideas for this 20 min observation. I was thinking of the Very Hungry Caterpillar but not sure if this is maybe too common.

Can anyone help with ideas, thanks in advance!
