This product contains 3 sets of 100 common objects (100 common objects but 3 different pictures of each one). This can be really helpful when you are teaching individuals with special needs. Each picture is fitted in a 3x5 box which you can either cut out and put in an index card box or keep on the page for pre-set arrays! THIS COMBINES MY SET 1, SET 2 and SET 3 SETS - Do not purchase them individually if you are buying this pack.
