Introducing Symbols To Preschoolers

Here's a great way to introduce the concept of symbols to preschool age children.
Find pictures to represent the names of songs you have been singing with the children.  I have legally printed off pictures from the internet and found pictures in books and magazines.  For instance, a picture of a star or stars would represent the song "Twinkle, Twinkle Little Star".  A picture of a lamb would allude to "Mary Had A Little Lamb" and a cute puppy dog would be the symbol for the song, "Bingo".
Introducing symbols at an early age is a great idea because learning music notation is full of symbols!
Using the picture idea above is not only a fun game for the children, it makes for a teachable moment.
