As far as consumable workbooks, you could use sheet protectors and dry erase markers or washable markers. I recently purchased from Rainbow Resource something sturdier and larger with a side opening, “wipe clean worksheet cover” from Roylco. I use one myself for my cleaning lists.
We started ASL (American Sign Language) recently. I use the same system used for Scripture memory and put cards in the box of the words we use. You can make up your own cards or Amazon has a box of 500 cards from Barron’s. I think that system is awesome and could also work well for other learning.
