In a previous post, I mentioned that I do not like to require practice cards for my orchestra classes because I want students to choose to practice on their own. Also, I feel practice cards are much more effective when they are used less frequently. There are times when I do need students to practice our concert music very carefully in order to be ready for our concerts Every now and then, I give students the 10x Perfect Practice assignment. I assign specific measures (very small chunks) from our concert music and students are required to play those measures perfectly 10 times every day. Sometimes, I have sectionals and allow students to accomplish some of this during class time. This works great for getting students to work on a specific small section of music and getting quick results from their practicing. Students learn that it's not hard or time-intensive to practice a few measures 10 times and it is motivating when they sense their own progress.
