MATH ROLLER

You can choose the addition and subtraction version, the multiplication and division version, or the fill-in-the-blank version (which includes additions and subtractions).

At each end of the roller there is one type of operation, and with the side adjusters you can change the numbers so the printed operations are different every time.

INK-REFILLABLE

The roller comes with a full ink refill and, when it runs out, you can refill it by removing the side adjusters and adding ink into the opening.

On our website we have refills available at this link.

We recommend adding about 10 drops of ink so the print quality is good and it does not overflow.

The ink is harmless and non-toxic, and is designed not to cause any problems for little ones.

The importance of reducing screen time

Affect eyesight negatively

Too much screen time strains the eyeballs and can create or worsen vision problems, especially in children.

The blue light emitted by screens is the cause, and it is more harmful when the screen is close to the eyes.

Difficulty concentrating

A large part of the content on social media (especially the content made for children) is designed to achieve the longest possible consumption time, which creates the habit of spending hours going from one video to another without using creativity.

If the brain gets used to receiving dopamine simply by looking at a screen, it becomes more and more difficult to have fun with activities that require effort.

Lower sleep quality

Prolonged screen use during the day keeps the brain active and makes it harder to switch into “rest mode” and stay there throughout the night (both in adults and children).
