This children's song teaches about rectangles. It is sung to the tune of B-I-N-G-O and describes that a rectangle has four sides but is not a square. A rectangle has two long sides and two short sides that are not the same length, unlike a square where all sides are equal. The song repeats that the shape is a rectangle.

1. RECTANGLE SONG
( to the tune of B-I-N-G-O)
There is a shape that has
four sides,
But it is not a square...No!
It's a rectangle;
It's a rectangle;
It's a rectangle;
It is not like a square...No!
Two sides are long; two
sides are short.
They are not the same...No!
It's a rectangle;
It's a rectangle;
It's a rectangle;
The sides are not the
same...No!
