You can design any activity for learning Danish. Sign up for yoga classes if the instructor speaks Danish. Study vocabulary by writing it on your shower curtain. Practice cooking Danish meals while watching Danish TV chefs. It does not matter. As long as you do something and keep doing more. But there is one activity I strongly recommend. One activity to support all the other activities. One activity is king of all the other activities. In fact, without this king, any attemt at learning Danish is likely to have a poor outcome. This activity is flash cards. You need to do flash cards every day if you want to speak Danish fast and fluent. It is just like training your abs. If you want a flat stomach, get out of that bed every morning and do your sit ups. It is painful and boring. But it becomes easier the more you do it. And the same goes for flash cards. Flash cards is a method for studying while increasing your memory. The method was invented by Sebastian Leitner. It is extremely simple. And extremely efficient. For every fact (word, sentence, expession, slang, vocabulary item etc.) you want to learn, you create a piece of paper with the fact on one side (in Danish) and the translation on the other side. Now, you need to repeat each card again and again until you never forget the facts. Lots of excellent software is available to do the job for you if you are not so good with a pair of scissors or if you just do not want to store tons of small pieces of paper. The software solution has another advantage. It spaces your repetitions according to how well you have learned a fact. There are lots of great software solutions for this. Some are cheap and some are for free. I recommend you try out different ones. Just google 'flash cards' and choose from the large selection of services. If you use iPhone, off course, you should get yourself a nice flash card app allowing you to create and study your own flash cards.
