Flash Card Register Box for Studying - DIN A8 Format (Lernkartei)

thingiverse

There are two versions of this card system, one featuring a rippled bottom that prevents cards from falling when there aren't enough to fill the largest compartment - the other version has a flat bottom. Using the "Lernkartei" System: 1. Purchase DIN A8 cards (74mm x 53mm, max 80mm wide) and create individual cards for each learning item, such as simple calculations like 1x7=? or more complex ones. You can also decorate each card with a MindMap to help reinforce the material. 2. Place all the cards into the first compartment. 3. Test your knowledge and if you pass, move the card to the next compartment. Repeat this process every hour, then again in one day, one week, and finally in one month to solidify the information in your long-term memory. 4. If you fail a test, return the card to the first compartment and start over from scratch. 5. Once all cards are in the final compartment, congratulations - you've mastered the material! I put this system to the test with my 7-year-old son who is in second grade learning his multiplication tables.
