Musical Number Patterns: Music Maker

Learning Centre Activity
Make some music by building up rhythms for four instruments. Choose a starting point on a number line and build a counting rule. Count in lots between 2 and 10 until you reach 36. Add your number several times on the number line to make a pattern. For example, set up a sound pattern where a trumpet waits on the first note, and then plays on every third note. Add a second or third number pattern for other musical instruments. Then play all of the sound patterns together to hear your music. This learning object is one in a series of five objects.
