The plus and minus training is suitable for all children from the middle of the first school year. Playfully, plus and minus tasks are practiced on three different levels of difficulty either in the number range from 0 to 10 or in the number range from 0 to 20.

The secure mastering of plus and minus tasks in the number range up to 20 is one of the basic skills and is an important prerequisite for calculating in the large number range.

When calculating against time, the children are motivated to improve their performance and thus also to repeat the games and tasks frequently. For every new best, there is a new puzzle piece for a reward picture.

Before the training starts, the children choose to play with Zahlenzorro, with Nick and Emma from the book Denk und Arithmetic, with Flex and Flo or with Zahlix and Zahline from the world of numbers.

Then it starts! There are a total of 4 thematic computing worlds:
    • Underwater: rearrange numbers
    • Space: calculate plus tasks and assign them to the right results
    • Jungle: Calculate minus tasks and assign them to the right results
    • Circus: calculate plus and minus tasks and assign them to the correct results

The children can choose the level of difficulty of the games themselves, depending on how many tasks they choose. The more tasks you select, the harder it gets. The goal is to solve as many tasks as possible in the given time.

The individual and best performances are presented in a structured overview and thus enable the child to keep track of his achievements at all times.
