A great tool that can either be used in a math notebook or can be a tool sent home with students to study independently. Students are able to fill in the flaps with answers and quiz themselves as they work on memorizing their fast facts. An alternate use could be having students draw an array or other visual representation of the fact under the flap ** I have added the 12's foldable, but it does not include 12x12 due to the formatting of the previous tables.
