This is our hungry crocodile learning box. Made from a old dish soap packet box, felt, and hot glue. We filled it with words for my daughter to spell and write. The whole point was to try to make studying fun for her and it worked! Everyone ended up getting in on it and she loved that members of her family picked out words for her to spell and write. Every piece of paper has a word on it and some have a star(for bonus words that she will be learning in school soon). Once she got the spelling/sounding them out right it went off to the side to pick another word out.
It was very easy to make and doubles as storage for all the words.
Note~ this could be done for every subject in school! Math you can write problems and have them pick out one to solve. Other subject you can write questions and have them answer them.
