So, how do you get your child to understand what "practice" is?? Well, every child is different and responds differently to suggestions, ideas, and tactics. But, here are a few that I have found to work over the years. Get your child a small calender with their favorite characters on it. Have him/her put a check or an X on every day that he plays for ten minutes on the songs and exercises assigned during that week. Be sure to let your child know that after that ten minutes, they can play whatever they would like. Some want to make up their own songs, some want to play favorite songs they have memorized from a previous lesson, whatever it may be, let them play away. As the teacher I reward my students with stickers for each day they practice if they practice every day of the week, but if your teacher doesn't do this, then you can be the one to award the stickers.
Another trick I have found helpful, is to make a chart at the top of every song or exercise assigned. Seven rows across for each day of the week, and four rows down for the numbers 1-4. This is to keep track of how many times the song has been played each day. If you want your child to play it more than 4 times each day, then add more lines down in the chart. The child then gets to check off a box each time they play the song or exercise. This can also be rewarded with stickers, or with TV time or game time, or whatever fun thing that seems to motivate your child.
I have some parents that have taken up piano to be able to help their child with it easier. If you are a parent that can play some piano or are learning to play piano, get your child to be the "teacher" and you be the student. Purposely playing it incorrectly, or sitting incorrectly, or acting out, to make your child correct you. Have them show you the "correct" way so that you can "learn" how to do it correctly. You can also have your child put on a concert for the family. One night after dinner, have them play all the songs they have been working on and some of their favorites, while you and the family are the audience. Even more encouragement and excitement can be given if you video tape the "performance". Children love to be praised and the more you give them, the more apt they are to continue the behavior they are being praised for.

The rewards for practicing are so great! For them, the feeling of accomplishment, the joy of being able to play their favorite songs, the value of having music with them the rest of their life. And for you, the joy of knowing that you gave them the value of music for the rest of their life, and being able to hear something other than Old McDonald and Chopsticks being played on the piano!!
