Upper 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.
