Frequently Asked Questions

Getting started

Yes, familiarising yourself with Vektor is a great way to prepare for the training period with your class.
You can find more information about how to try Vektor here.

See our tips for preparing for a successful start with Vektor here!

No, it's more or less only in the login screen that the language is used. The actual training is language-free and can be used by children regardless of which language they speak.

No, it's completely free of charge!

Before you start training, you need to create a username. If you are a parent, you create a username here. Click Create Username and follow the instructions.

If you are a teacher and want to create several usernames to your class, you click Create Account on this page and follow the instructions.

If you have an iPad you go to App Store and search for Vektor.

If you have an Android you go to Google Play Store and search for Vektor.

During training

After 40 training sessions, a small outro is played. You can continue playing if you want to, but some exercises will not increase in difficulty because the children will reach the maximum level of certain exercises.

Yes, it's possible to do several training sessions with Vector during the same day.
However, the program has a barrier that will not allow you to log in again until two hours after the latest completed training session.
In general, we recommend to let the children train once a day until all 40 training sessions are completed, as this is the way it was tested. Training too frequently may also result in the children getting too tired and losing motivation. But training two sessions a day every now and then, for example, to catch up after absence is okay. See what works best for each individual and for your organization!

We recommend that the children train 30 minutes a day, but it is possible to shorten the training sessions to 20 minutes by signing in to the teacher account, clicking on the student's username and ticking the box for "shorter sessions".

The exercises that appear for a user is partly depending on how that specific individual has performed in previous exercises, and partly depending on which training plan that is connected to that account.

As a way be able to continue to implement improvements and evaluate new exercises, the training plans are randomized between accounts and variations between students may occur.

The basic exercises evaluated in research are however the same in all training plans.

There are several options for how to make up for missed training time with Vektor, and the most important thing is for you to make a plan that works with your group and organization.

The student who is behind with Vektor due to absence could train an extra session later the same school day, for example at the after-school activity or during another class, if possible.

Another option is to allow the student to train extra at home, if they have access to a device compatible with Vektor, or in case it's possible to borrow one from school.

It's also possible to prolong the training period for the students who have fallen behind with Vektor, and give them some extra days to complete their 40 sessions.

It's OK to take a short break and stretch when needed. Sometimes, changing positions or stand up for a while can help regain energy and focus.

It's OK for the children to train with Vektor at home with the usernames they got in school, as long as the family and school communicates about the training and make a plan together that work for both parts.

Allowing the children to train at home some times can be a good way to involve the parents in the Vektor training, and a good way to make up for time the children may have missed if being absent from class.

We recommend using headphones as a way to avoid outside distraction and for the children to be able to focus on their own training.

Vektor includes sound effects that are intended to increase the gaming experience. It's OK to turn down the volume and work without headphones, or to turn it off completely in case the children get disturbed by each other.

Research has shown that 6-year old children training with Vektor during 8 weeks get an improvement in math that is equivalent to what you would normally see during a whole year.

These results have been seen on group level, and just like with anything else, individual differences are expected and no improvements are guaranteed.

The idea with Vektor is to allow children to train their working memory and give them a good fundamental understanding of numbers, to make mathematical learning easier going forward.

Vektor is designed for - and testet on children without any previous mathematical knowledge, and they are supposed to learn in their own pace without requiring further instructions from the teachers.

If you notice that many children are reaching levels in Vektor that are new to the class, you can take the opportunity to go over those challenges at the assembly or in the math class, if you like.

Besides the practical work with ensuring that the students get their usernames and that you have enough tablets for everyone - the most important thing is for you to be present while the children are training to be able to give them support as needed.
Here's some advice on how you can prepare before starting with Vekor, and here's some advice on how to support the children through the training period.

Many schools prefer to have all children in the class work with Vektor at the same time,  while others prefer to split the class into two groups or have even smaller groups of children training together.

Think about what will work best in your situation, and feel free to try as you go!

In this video you can hear how other teachers have reasoned around group sizes.

When you are logged in to Your Account at Cognition Matters, select the username for the child who's training you would like to adjust and then check the box "Friendly mode" to make Vektor less scary.

We recommend an intense training period with Vektor, with 4-5 30 min sessions per week during 8-10 weeks, until all children has completed 40 sessions.

The reason for this is that this is what has been tested in research studies and that we have seen has given children results.

No. Vektor is meant to give children a better foundation for learning and give them a better understanding of numbers. It's not meant to replace the ordinary math class and we recommend working with Vektor in parallell with your ordinary math class.

Technical support

The training data is anonymous and can not be linked to any specific person. The current system does not provide the function of removing existing training accounts. However, training accounts that have been inactive for a longer period of time will automatically be put on file.

The current system does not allow transfer of existing training accounts to/from/between teacher accounts. A legal aspect that must be considered is that training data is classified as sensitive data (see our Privacy Policy).

No, you can not change your avatar after the game has started. Equipment that you collect during the game can be changed, but the character can not be changed.

For legal reasons, we are not able to allow users to type in other names than those generated, since we cannot keep information that can connect training data to an individual.

In case you have registered an account but not yet received an email to confirm the registration, the first thing you can do is to check your spam folder to see if the email has ended up there. If you still cannot find the confirmation email, the email might have gotten stuck in another folder and you may have to contact your IT administrator for further support.
Another alternative is to register an account using a different email address.

The most common reason for this is that the user had internet problems on the device and has switched to another device which he/she has been logged into on Vektor at some point before.

The user will then see the items that was in the program last time he/she was logged in to that device.

If the internet connection is stable, the user will see the latest items the next time he/she logs in, and can continue training as usual.

If you have one student who have trained with Vektor, but the training sessions doesn't appear on Your Account at Cognition Matters, it is usually because of one of the following reasons:

Either the student has used another username when logging in to Vektor, or the device the student used was not connected to the internet during those sessions.

We suggest that you sit next to the student the next time he/she logs in to Vektor, to control that the right username is used and that the device is connected to the internet. If the problem still persists, please contact us at
