Each student needs 4 squares of construction paper.
Fold square in half from corner to corner creating a triangle. Crease. Open square and fold in the other direction and crease again.
Now open your square and on one of your folds cut along the line created by the fold all the way to the center point. When you have finished cutting that one line, overlap the two sides of the cut and glue or staple.
Now you should have one section of the pyramid. Repeat the directions above 3 more times to complete the 4 sides of your pyramid. Now students can cut and paste instrument pictures and label the instruments in each segment or side of the pyramid.
Glue or staple the 4 segments together to complete the project.
I hope these directions make sense. If you need further clarification please don't hesitate to ask!
