Mag-Mag / interactive toy

How to teach children to tell the difference of those they can eat and those they cannot eat? A book? A lesson? Or … ?
Why don't we teach them through games?
Mag-Mag is a series of magnetic wooden toys which is aimed at teaching children to identify the articles they cannot eat.
We have a large plate which is printed with a baby’s face on its surface and several small wafers which refer to edible and inedible articles.
You can stick the small wafer to the large on if it refers to an edible article, but you cannot do so if it’s and inedible article.
Through this fascinating process, children could learn things fast and easily.
