Some students experience great difficulty in visualizing the relationships of one shape to another.
For example, they may be unable to use the relationships between a triangle and a rhombus to predict how many triangles will cover the rhombus. These students need more hands-on experiences to visualize the relationships between the shapes. They know that if there are three rhombus shapes and two triangles are in each rhombus, then there are 6 triangles in three rhombus shapes.
