In the children's game 1x1 Dragons, kids skillfully multiply with numbers from the small multiplication table to be the first to fill their own bingo card and win. The rolling of the dragon eggs adds excitement and variety. Both beginners and pros can have just as much fun with this game, as the rows can be freely chosen by the children, and the difficulty level can be increased. This playfully promotes a solid mastery of the small multiplication table. In this varied game, based on the well-known bingo principle, children enhance their mathematical skills by multiplying cleverly. They roll the dragon eggs into the number caves and multiply the numbers with the chosen multiplication row to cover spaces on their bingo card. The children play with self-set goals, together with friends or siblings. Additionally, relevant topics for elementary school are covered.
