Brainstorming is a very effective tool for these children. Usually prefer to read adult level books. Tend to self-evaluate. Very high standards. Hardest on themselves.
Some gifted children become perfectionists.
We can assume that if the child is a perfectionist, at least one parent is a perfectionist also. They need to feel valued and can become critical of self and others. Gifted children are not easily satisfied with their own speed. They get frustrated easily and it becomes very stressful on them because they want to be perfect in everything they do. Can be very dramatic.
