Education can be very boring, unless made entertaining. And often teachers are unable to make children register what is being taught. This is more so amongst the youngest kids.
However, one interesting and entertaining tool is that of finger puppets. This means of teaching has been used since ancient times.
Finger puppets are not just those that are created from some material or the other and worn on the finger, but also include the characters painted on the fingers.
A good puppeteer can usually display ten characters at one go, by effectively using each one of the fingers to enact a character. All in all, anything that has an element of entertainment brings about long term registration of what is being taught, puppetry being one such effective method.
