Hello,
I came across this (http://www.songsthatteach.com/index.php) and thought some of y’all might enjoy it too. They are bilingual songs to teach the language. It is on sale at homeschool coop right now. (https://www.homeschoolbuyersco-op.org/sara-jordan/?c=1) The sale is only for Spanish and French, but their website has Mandarin, too.
