* The Lunch Box Game.
If you're doing a history or science topic, this activity helps children develop the skill of using and questioning evidence. After lunch, borrow a child's sandwich box and ask the class to guess what it held at the start of the day. Begin with the physical evidence - crumbs, drops of drink and crisp wrappers. Move on to eye-witness accounts. Who sat beside the lunch box's owner at dinner time? What can they remember? Look for gaps in the evidence and conflicting testimonies. Draw parallels with archaeologists' and historians' work about evidence

* White boards
Dry wipe boards for the purpose of guided writing can be made by placing a sheet of white card inside a clear plastic ring-binder wallet. These work with dry wipe pens and allow you to slot word lists, pages to be annotated, line guides or templates to write on, into the plastic wallet.
