6 to 8 year olds

Martín plays with a giant dice in his school.

The dice has a different shape on each face, as shown in the figure. If every time Martin pushes the dice it rotates once on one of its edges, what is the least number of times Martin should push or rotate it, so that the trapezoid is on the upper face?
