The teachers I know tell me it's being an involved parent. Teachers invest a lot of their life into your child. They spend countless hours preparing lessons, grading papers and pouring knowledge into the minds of the children in their care. In most cases, the only time they hear from a parent is when something goes wrong. So if you really want to show your appreciation, be a present parent. Get involved in your child's education. I'd like to share my thoughts In Praise of Teachers. And if you need to give them something to show your appreciation, a sincere note from you is worth more than you will ever know. Here are some nicely decorated Teacher Appreciation Notes your kids can fill out and share.
