Metals, alloys, acids, bases labels for card sort

I have created a laminated chemicals, elements and compounds cardsort that is colour coded and kept in A4 plastic wallets. Red = acid, blue = alkali / CO2 / water, grey = metals, non-metals = elemental colours where possible. I make 6 lots of these so that I have one set per table. They can be used to: (1) make word equations (and by extension symbol equations), (2) sort metals from non-metals, (3) sort acids from bases (4) sort elemental metals from alloys. Many other uses also. Feedback to my TES inbox please.
