Which familiar children’s songs demonstrate the canonic imitation related to fugues?

Familiar children’s songs that demonstrate the canonic imitation related to fugues include "Three Blind Mice," "Row, Row, Row Your Boat," and "Frère Jacques."123

These songs are categorized as rounds, which are a type of canon—a musical form based on the principle of strict imitation where an initial melody is imitated by one or more parts at a specified time interval. While these simple rounds are sometimes referred to as "fugues for children," a true fugue is a more complex, evolved form of polyphonic composition. In a fugue, various voices state a theme and then seem to "flee" from and "chase" each other, a technique that shares the imitative roots found in these familiar folk songs.231
