Put any of the following inside of plastic bottles, cans, etc: rice, popcorn, erasers. Just so ya know, the popcorn inside the little Gerber juice bottle shown above, makes alot of racket, as my daddy used to say.
We would use our "instruments" and march around the room or whatever.
The wooden blocks were used for when we would sing "Wise Man, Foolish Man". We would beat them together (building) for the wise man part and rub the sandpaper sides together for the "Foolish Man" part. Per my husband when I made these "They're going to mash their fingers beating those blocks together." I figure they won't do it but once and then they'll learn not to do it again.
I also took pictures of each of the children and used them ALOT. One thing I used them for was to put each child's picture on a fat popsice stick and let them hold it when we would sing "I Am a Child of God".
The "drum" shown above is just a couple of balloons stretched across a tin can - said tin can having been emptied of all contents first.
Little girl on a stick is what we used for singing "Jesus Wants Me for a Sunbeam". I tried to make/match cutouts to children's looks.
