One sheet for children to write on with a pictorial list of all the Halloween items they are looking for - witch, cat, skeleton, etc. They need to find the pictures (which you'll have hidden around the hall or outside area, etc.) and write down the number (shown in red on the hidden picture) next to the item on their list. The second document contains all the pictures themselves (with the red numbers on), A4 size for sticking up somewhere (hard or easy-to-find places) and the third gives all of the answers for checking they've found them all.
