Lesson Plans

When we did the lesson plans, I couldn't think of creative stuff to do and was always thinking that it would be to hard for them to understand. But we have to think that nowadays everything is different as we learn it. Young people now already more as we do. So why should we underestimate them? I think if we give them difficult tasks it is a challenge for them, of course it depends on the class. But when I saw other lesson plans they had so good ideas, that i would definitley use in class but I would put in other order. How could we use moddle for the lesson plans?
