I love this collection of books by Claire Freedman and Ben Cort- SO funny - if you haven't seen them, hop over to Amazon to see them! Monsters, Aliens, Dinosaurs, Pirates, It is a nice way to finish the craziness of Halloween without being too "Halloween-y". Of course, as the theme is monsters (and aliens, etc.) in underwear, these children's books are good for any time of the year!
A couple years ago in the Dollar Spot at Target they had some really wonderful heavy-duty chipboard underwear games. These were perfect for creating rhythms on one side with words! I have included a few cards with colors, shapes, and lines for you to begin the process as the underwear pieces are no longer available.
There is so much you could do with the rhythms once they have been created - transfer the rhythms to F and D in the d minor pentatonic scale being used, transfer to unpitched percussion, small groups could create non-locomotor or locomotor movement to illustrate their shape and pathway! Possibilities abound! If you would like the pdf, please send me an email at email@example.com.
