She has not used glue before - so with this one she just put the glue on and I placed them. It's amazing that I can ask her "So what are you?" and she immediately says "omnivore". She has learnt so much.
We had so many pictures that we separated the meat and veg / fruit from the others and then she stuck all the extra pictures onto the back of the poster. She did this all on her own.
I laminated the poster for her once she was done so that we don't have to worry about any of the pictures falling off. So even if they only got a little bit of glue in the middle it was enough.
