Derzelis thinks that digit recognition is a must when it comes to the abilities of preschoolers. She created an interactive elearning game to teach children the order of the digits from 1 to 7. This is how the game works – first, three snowmen appear on the screen. Derzelis tells the players to close their eyes. In the meantime, one of the frisky snowmen hides away. Derzelis tells the players to reopen their eyes and press on the digit located below the missing snowmen. When kids press on the right digit, Derzelis utters the corresponding ordinal numeral. This activity is ideal for increasing both the mathematical and the linguistic abilities of youngsters all over planet Earth! However, this is only the first level of the game.
