A set of parallelograms that were (I think) a teaching tool for first-graders or so? They were thin colored plastic and you put them together in various ways to form two-dimensional shapes.

Kinda. Can't tell you what they were called, though.

Tangrams?

Those were actually 5 triangles, 1 square and 1 parallelogram, but might be what you're thinking of?

They still make them, and there's even a game called 'Tangoes' that's ... you know, 'rainy day Good-For-You! fun'.
