Let your child figure things out. She'll find out for herself that the scotch tape won't work on her wood construction, and it will mean so much more for her to learn this by her own trial and error. And when she's finished, she'll have done something all on her own, and you'll see a real boost to her self esteem. It usually starts between eight and ten. Most of us think that a child who is a good drawer is more artistic than the one who is not.
Realistic draftsmanship is just one art tool among many.
In fact, the artist who can only draw realistically won't get very far. Art is about communication, about balance and unity, about color and line and texture and so much more than just drawing realistically. This is why when I teach I give kids a lot of abstract projects, because abstract projects really emphasize all these other skills, plus it gives them the message that art is not just about making something look like something. And starting at about age ten a lot of kids are ready for projects where the emphasis is initially less upon creativity and more upon learning a new skill. In these projects you want to take it step by step with the child, giving them direction and sometimes asking them to do it your way while they are learning.
