Other eps with the following Youth Marching Band clips

[gameshowguy2000]

OK, I remember there were eps with some of the following Kids' Marching Band clips (you know, the shapes and numbers series). I need to know which ep #'s have the following clips:

In the shapes series: Rectangle (I'm sure I remember the kids did this one)

In the numbers series: The band plays 1 and 3. (I remember those as well, was 4 the last one they did?)

If anyone knows which ep #'s feature these clips, let me in on 'em!
