The taped X in fron of a unit block area in a preeschool indicate that .. ?

Question

it means that only teachers are allowed in the area or it is the area where children should not build?

Answer 1

to me I woul.d think this X  is where the children can build with blocks, is the X on the wall, perhaps it is how tall they can build or if it is on the floor it shows them where theay can play, or are there other symbols used in the classroom to represent different areas and X just is a visual clue to mean block area, Why dont you just the preschool teacher???

Answer 2

You need to be more specific, I'm not understanding what you are asking.
