Muslim children tend to do this when learning to recite the Qur'an in their Qur'anic classes. This has nothing to do with religious practice and is more likely a result of the rhythmic verses that the children are reading which makes them rock back and forth as they learn.
Also it should be noted that this is more common in south asian countries and may not be as common amongst the children of the Arab world or Africa.
Hope this helps.
