As you know, OpenGL contains rendering commands but is designed to be independent of any window system or operating system. Consequently, it contains no commands for opening windows or reading events from the keyboard or mouse. Unfortunately, it's impossible to write a complete graphics program without at least opening a window, and most interesting programs require a bit of user input or other services from the operating system or window system. In many cases, complete programs make the most interesting examples, so this book uses GLUT to simplify opening windows, detecting input, and so on. If you have an implementation of OpenGL and GLUT on your system, the examples in this book should run without change when linked with them.
I am so excited to be following along as I read this book! I ordered a book for a dear friend and colleague of mine who's in Kindergarten. I'm making the move to 1st grade, but I'm thrilled I can still use so much of your stuff. Ok…on to the questions:
1. I would say that thanks to the Common Core, I am more comfortable with teaching Number Sense now…BUT I had never really approached number sense in the way I have now so I have a long ways to go.
2. I have started number exploration activities that include Part-Part-Whole. I've used dice, unifix cubes, counting bears along with the Part-Part-Whole mat to help develop a better understanding that there are different ways to make a number. I have also used exchange games like Win a Flat and Win a Bundle to help with place value concepts.
3. I know that I have to be more cognizant of different strategies that lead to the same answer. I definitely plan on having my students take the time to explain how they arrived at an answer more frequently so that students can be exposed to different methods and decide for themselves which would be the best for them. I would also make an effort to present Math problems and allow them to explore possible solutions the same way Chapter 1 begins.
