Please forgive me if this rambles on. I have a lot going on in my head and will try to present it coherently. 6 years ago my district began the search for a standards-based math program for grades k-4. Investigations was selected because k-2 teachers really wanted the program. The 3rd and 4th teachers were not convinced. After 1 workshop day where we were basically sold the program not trained how to teach the program, we were told to go teach and have fun. No sustained training or support was given except for two days the following fall. Every year our state math scores went down and our parents were beside themselves because they couldn't figure out how to help their children or how we were teaching. Last year we were allowed to supplement Investigations with some good old fact learning. Amazingly, our test scores went up. Maine's MEA test isn't all multiple choice. It has short answer and constructed response questions as well. Now I know that Investigations has helped our kids with being able to explain their thought processes and coming up with other ways to solve problems. The games provide tools for using some of the skills we teach. But, it doesn't do enough with learning the basic facts. In my opinion, the spiralling that is suppose to take place so the students will have multiple opportunities to work with a concept isn't working out. This year we are piloting a new book that works with Investigations as the supplement. I don't remember the company, maybe Foresman? Not sure. We teachers are extremely excited and look forward to trying it out. I know that I have a biased against Investigations. I didn't want to use it, struggle with teaching from it, and find it cumbersome. I guess I'm writing this to get it off my chest. I'll write more when I've had my turn with the new program. Also when I learn the name of the new book incase anyone else is interested or has used it. Thanks for reading. I've been teaching for 14 years and sure could use other's thoughts.
