Make your beginning orchestra students earn their "bowing license!" Often in the Suzuki method or personal preference of teaching beginners, we tend to teach the instrument separately from the bow before putting the two together. Give your beginners preliminary exercises that will allow them to earn their "bowing license" to keep in their case.
There are 4 bowing licenses on the page. You can copy and laminate them according to how many you need. You will get an editable word document so you can put in the name of your own school or teaching studio. This also comes in a cello version. In my school beginners have to make 100 perfect pencil bow holds in order to earn their bowing license. Have fun!
