Who will benefit from the course

For children who do not know numbers and digits or know them but cannot count. They make mistakes when counting, cannot distinguish geometric shapes and colors, cannot orient themselves in time, confuse right and left, are inattentive, and do not want to learn because it is difficult and boring for them.

A minimum of 22 classes

are included in the course, consisting of one-on-one online lessons with a teacher

Minimum of 6 months

4 course options for children of different ages and levels of preparation.

From 4 to 10 years old

different course packages for kids of any age

Fosters an interest in learning. The children “play” and easily absorb math, learn to puzzle things out, and make non-standard solutions under the teacher’s professional guidance.

The Kidskey platform was created
especially for kids
All classes and are held on our online platform, one-on-one with a teacher. There are no recorded videos. These are individual sessions (child + teacher). Each class runs for one hour. The session includes an online class with a teacher (25 minutes) and completing the interactive homework on the platform (20-25 minutes).

Experienced teachers

teach your child new things in a fun way, fill in the gaps in their knowledge, and find the right approach to your child

Interactive tasks

each lesson and homework task is a mini-game. Forget about boring lessons!

Christina, Leon's mother, Australia
We decided to learn math, learn to count and memorize numbers, and Leon has also learned how to solve math problems and can even design short math problems himself. He's also become a little explorer: he walks around with a tape measure and measures everything. Once I was cooking in the kitchen, and...

Anna, Lucas' mother, Sweden
Before Kidskey, my son didn't want to count or learn numbers, and wouldn't sit down to read even in exchange for candy. One day, I talked him into taking a trial math class, and oh, my goodness! He loved it! Now Lucas keeps asking me when the lesson is. I don't need to push him. He's learned to coun...

Sarah, William's mother, USA
We haven't seen this kind of approach to teaching children at any other school. My son is 4.5 years old. When we started, he had trouble orienting himself in space and could only distinguish between up and down, forward and backward. Right and left were a problem. There was no way William could reme...

Meili struggled with math from the very beginning. She is very active and finds it difficult to sit in one place for half an hour. She was always distracted at school and jumping from one task to another, and she couldn't solve any of them correctly. She couldn’t concentrate. At the first Kidskey cl...

Top FAQs

How are Kidskey classes different from regular school classes?

Kidskey's Mathematics course includes additional practical tasks and topics that build interest in the subject, and a positive attitude towards math. Kids will learn that solving problems and examples isn't difficult if you know HOW to do it, and will stop being afraid of them. Our teachers will teach your child to look at a problem or sum without fear, to find the right solution and enjoy the success. At Kidskey online school, learning is game-based, and as a result, basic knowledge forms the foundation for mastering more complex material. In addition, classes are conducted one-on-one with a teacher, whose attention is completely focused on your child.

Does a child need the full Mathematics course if he already knows numbers or can count? Can we choose classes only on the topics we need?

Mathematics is not just numbers, it's counting forward and backward, the ability to solve simple problems, and an introduction to geometry. Math classes develop a child's attention, thinking, and memory. The program at Kidskey is a system of classes, with each lesson building on the material in the previous one, so it's better not to break up the course.

My child can't sit still and has trouble remembering things, will she be able to do the Mathematics course?

The exercises in the course are designed to not only teach, but also to develop memory, imagination, attention, and thinking. Learning is presented as a game, so the child doesn't even notice that she is learning.

I'm looking for classes to help my child develop logical thinking, would the Mathematics course be suitable?

Yes, it would. Each class includes activities to develop attention, memory, imagination and reasoning skills, in the form of rebuses, tasks and puzzles.

Will the Mathematics course help to prepare my child for school?

Yes, the course will give children the basic math skills they will need in first grade. In addition, the classes include exercises to train memory, attention, logical thinking and imagination. Your child will learn to memorize, orient themselves in space, analyze and draw conclusions, and learn number compositions, which will help them with addition and subtraction.

How do I engage my child in learning if he doesn't seem interested?

Learning at the Kidskey online school is based on easy communication between a teacher and a student. There is no rote learning in class. The child plays and learns, and thus understands that math is interesting and easy. Our students enjoy doing their homework on the interactive platform and look forward to their next class. And most importantly, there is no coercion. Kidskey is about learning with fun.
