Do you home school? Does your child need help with learning to read or spelling tests at public school? Why not make your own flash cards? They are cheaper then the pre-made packs you can buy at the store and so simple to make.
The oldest Fun Tester is in 1st grade so I made him up some Dolch List words to help him get some review. I took a pack of colored index cards and wrote out the words. I then used a hole punch and put a pipe cleaner through to connect them. Easy, colorful and DONE at a fraction of the cost of store bought flashcards!
This would be great for just about anything! Like math problems on one side with the answer on the back, states and capitals, etc.
