Your children will be continuing to learn about Carnival of the Animals this week, but will also learn about the half rest:
Since the students already understand the concept of a note longer than one beat, I expect them to learn this one quickly. As soon as I teach it to them we will play a much loved game called Busted! where the students flip over cards and read the rhythm they have created. But! If they flip over a 'Busted!' card, all of their cards go back in the pile. This is a great way for me to quickly and quietly assess how well students are grasping new and remembering old concepts.
The next step in the learning process is to have them write their own rhythms using the new rest they have learned about, and then using it with Rhythmic Dictation.
