Classification by levels 
Lower Secondary
REMARK: The indication level is only intended to suggest that
the following pages contain materials which may be useful in learning and in
teaching some subjects at that level. Notice that the corresponding materials
were not designed to fit into any specific curricula topic, and that an exhibit
from Atractor can contain different levels, usually structured in layers of
increasing difficulty. We think, however, that the indication of a level can
be useful to those who look for materials potentially useful to the teaching
of mathematics, but it is up to the teacher to adapt them to the classroom.
