I have been in gifted (we call it Challenge) since 3rd grade. I am now in 10th grade. Elementary school was definitly, 100% worth it. I loved the teacher. I loved the activites she did. She was one of those teachers, though, that went way above and beyond. We had these things called Big New Words that we did at the beginning of class, which we had once a week for about 2 hours each week. They were vocabulary words, but they were SAT words. She would say the word and we would guess how to spell it. Then she she would give us the correct spelling and the definition. Anybody that spelled it right the first time got a sticker. At the end of the year, she had a huge pool party at a local community pool where she worked as a life guard in the summers. Anybody that had a certain number of stickers could go. But, the last day of Challenge, she would spend the whole class doing Big New Words if she needed to to make sure that everyone could go to the party. We did so many things in her class. It was a blast. Also, she would plan things like field trips that have to do with certain careers. For example, she would take a bunch of people to a veterinarians office. The vet would talk to them about the job and then they would "operate" on little stuffed animals.
Middle School was OK. It was very different, though. We had it once or twice a week for 1 period (about 45 minutes). We did a lot of things, too. We wrote a book for a first grader starring them. We also invented toys and stuff. We did a lot of things with careers and stuff. The teacher would find out what you wanted to do and she would plan trips. For example, people that were interested in journalism or weather went to a local television news set and watched a taping of the noon news and talked to the weather guy and stuff. People interested in animals went on a behind the scenes tour of the zoo.
High School is pointless. It is basically an excuse to skip school and nobody takes it seriously. We don't have class. At the beginning of the year, you fill out a survey. Based on that survey, the teacher will plan things people are interested in. If she finds something you might be interested in, she will hunt you down in class, talk to you for about 5 minutes, hand you a permission slip, tell you its due tomorrow, and leave. That is basically the only contact you have with her unless you go on field trips. Last year she wanted to make us read certain books every 9-weeks and then we would have a meeting to discuss each book. Everyone went to the first meeting, but only a few read the book. For the second book, a few people went to the meeting, but only 1 person actually read the book. I think she just gave up after that. LOL. I really don't get the point of it.
