Tutorial on Regina Caeli, simple tone

A new idea for this school term - a weekly short lesson with a quiz. I'm conducting a zoom class on Friday mornings. I think the main drawcard for the kids involved is the quiz at the end. Each week I nominate a new piece for next week and prepare a worksheet with a crossword puzzle for them to learn the vocabulary.
Here's the link to the Blooket quiz for revising the vocabulary and a little bit of solfege:
