1x1 helps to teach and train how to multiply two numbers up to 10x10=100. The app doesn’t use any words, so the app can be used in any language.
The app is tested by teachers, what you can find in references. : "1×1 is a fantastic way to learn and practice math facts. I recommend 1×1 for ages 7-10, (...) and special needs students."

The app is split in 12 levels. In every level there are ten equations, which the player has to solve.
The app contains all possible multiplication equations with the numbers from 1 to 10.
Our apps are based on a modification of the Leitner system:
That means, the questions are repeated until the player gives the right answer. Thus, the answers will be incorporated into the memory. So it creates a real learning effect.
If the player answered all correctly, then the level is finished. And the next level will be open only if the scores are enough.
To earn the third star, the player has to play the level again, this time even without the help of the balls.
In the second last level there are 17 randomly selected equations of all equations asked again.
In the second level there are 25 randomly selected equations of all equations asked again.
The player could play the last level again and again for good exercises.

The game is finished, when the player has received all the three stars for each level.
You can reset the scores, so that the player can repeat the lessons at a later occasion,
or another player could do the exercises or you can replay the last level again and again for good training.
Please notice, that our apps are real educational apps, made​​, among others, for the classroom and homework.
In our apps the education is more important than fun. Our apps create a real learning effect.
Our apps are more likely doing homework instead of playing a game. So it can be some work for children to finish our apps.
It might be helpful if the parents or teachers support the child's motivation.
Therefore the reward of the work is that the player will master all multiplication tasks up to 10 in the future without problems.
In the category 'more apps' you can find other apps we produced.
The app can also be played by adults for good exercises. The tasks are the same, just the design we produced more for children.

We would very much appreciate any feedback from you:

Recommended for ages 8 - open
