Koyatko! Add Subtract

Koyatko! Add Subtract is a maths game for teaching preschoolers and kindergartners the basic concept of addition and subtraction. Older kids may also benefit from practising simple addition and subtraction and collect rewards.
Prerequisites:
- ability to count up to 20
- ability to read numbers, "+" and "-" signs
* Knowledge of addition and subtraction is NOT required *
Let the kid work out the answer!
Unlike most of the early math educational games on the market, we not only just provide questions and answers. We also provide a working area for kids to work out the answers on their own... with wiggly Koyatkoes! Guidance may be required for the first few questions, but you will be amazed by how fast your kid can understand the basic concept by adding and subtracting kitties.
Progress tracking and difficulty adjustment
The game saves the progress of each child and adjust the difficulty of the questions as the child progress. After the child completed a certain number of questions, he/she will get a certificate to acknowledge his/her achievement.
Collect rewards and practise more!
Practise makes perfect. A reward system to collect Koyatko's outfits is in place to encourage kids to do more questions.
Free to play and only one ad per game session
We understand how annoying it is to have ads popping up while your child is playing games. So we limited the ads to only show once at the beginning of the game.
