Practicing chords doesn't have to be boring. I love to pair chord practice with pop songs since the majority of pop songs are limited to just 3 or 4 chords.
Although pop songs can have some pretty complicated rhythms for beginning piano students, they can enjoy accompanying YouTube videos with an understanding of chord symbols. Or they can sing along as they play the accompaniment. Choosing songs that they are familiar with really ups their ambition to practice and helps with audiation.
I've compiled a list of familiar primary songs from The Church of Jesus Christ of Latter day Saints with just 2 or 3 chords for my younger students, but having some fun pop songs in the makes chord practice more appealing for my older students.
