I recently came across this website which is loaded with all kinds of printables, games, crafts, puzzles, kids jokes, etc. A great storehouse of ideas and creative worksheets all ready to print out! If you type the word "music" into the google search at the top of the page, you will find some fun music related items, but the entire site is also loaded with ideas and printables for holidays (Valentine's Day is just around the corner!) and for themed events. If you are planning a studio theme or just like to decorate or put together a bulletin board, this is a great site to check out. There are over 50 themes with all kinds of games, activities, puzzles, worksheets, and ideas.
I saw some adorable valentine bookmarks with kids jokes on them - A really fun idea to give to your students around Valentines Day or go to the Kid's jokes section and print out some kid's valentines jokes for some fun during lessons!
Just another resource for your studio! I hope you can find lots of great ideas to use with your students!
