If you are learning vocab it can be great fun to write words on those smallest size sticky post-it notes. You can write the translation and the grammatical info on the back. Then you can stick them to every day objects. For example: you can stick "молоко" on our milk bottle in the fridge "масло" on the butter and "холодильник" on the fridge door. This is not only a good method to learn your vocab, it also helps your brain to become quicker at recognising word imagery. Have fun. It also impresses the visitors.
