Resources for Teaching C to High School Students?
mctk asks: "I'm a high school teacher who, disappointed with the lack of computer science in school, has promised to teach a few motivated students programming after school. As an enthusiastic novice with three semesters of C under my belt and a few side projects worth of experience, I feel competent yet ignorant. I would really appreciate suggestions for resources on C that are written to be accessible to high school students and contain lots of ideas for activities. Perhaps you've had success with a series of books that spans beginner to advanced? Do you have any activities you would recommend? How would you map a student's first year of coding? I welcome any and all suggestions. While we're on the subject, is there a brace style that is most standard in the industry?"
Don't try to teach the language, any more than you teach someone how to use a pen when writing.
Teach the mentality, the methodology of problem solving.
Teach basic algorithms, data structures and coding theory - give them an understanding of where the libraries they are suing will come from.
More importantly for modern world working teach colaberation, give them a real group project to do, each of them writing different interfaces or different parts of an interface for a whole program (something like a simple game such as tron is ideal for this)
By doing all of this the language becomes almost incidental - which is really what you want, who knows what the demand for C, C++, javam C# will be in a few years time, but learning the right methodology and colaberative practices will stand them in good stead for years to come.

But don't teach them C. Teach them a language that focuses on how to structure programs without bogging them down with memory management, pointers, etc, etc. A firm understanding of OO would also be much more useful and much easier to grasp.
There's a reason there are so few resources on teaching C to high school students; it wasn't meant to be taught to high school students.

In high school, I took an AP Computer Science class that taught C++. If I understood then what I understand now, learning C++ would have been a whole lot easier. My teacher focused too much on the language instead of concepts.
After several failed attempts at trying to learn how to program, I finally understood basic concepts such as variables, integers, arrays, etc. I then took a more basic computer science class, "Algorithm Design/Problem Solving," that used the book Programming Logic and Design. This book does not use or concentrate on any specific programming language. All our assignments were done in pseudo-code and we had to show the logic of what we wanted accomplished. I have to admit it was a lot easier trying to convey the logic without having to worry about the syntax.
It's been a couple semesters since I've taken that class, without any programming in between, and now I've picked up The C Programming Language. I am currently half way through the book and ,I must say, I finally understand and appreciate the concepts being taught. I wouldn't quite recommend this book to the pure beginner, because it assumes knowledge about basic concepts such as variables, compiling, etc. The book, at a little less than 300 pages, is written and presented much better than the 1000+ page programming books I've run across.
If I were back in high school, I would love to have these concepts introduced at a gradual progression. Basic programming concepts -> Logic & Design w/ pseudo-code -> the actual language of choice using an easy to learn (30 minute intro) compiler. Of course, hindsight is 20/20 and I'm not too sure if I would have paid as much attention to the first two concepts. Since you are teaching in a high school, I take it you have 2 semesters to teach the class. Perhaps dedicate the first half of the first semester with logic. You can have them play different logic games and tie that in with the lessons.
Creating a good foundation makes learning and teaching a whole lot easier.

If you want to teach basic programming skills using Python, there's a very nice free book which can help: How to Think Like a Computer Scientist: Learning with Python
