1. What did I
learn?
I learned how algebra manipulatives can be FUN! Before Mondays class I couldn't picture how manipulatives could be used with abstract concepts like algebra. I remember learning how to memorize the steps involved with algebra. Last year I tried helping my daughter learn how to use the FOIL method. She was very confused and had trouble doing the problems without my help. I have a feeling that the manipulatives would have made more sense to her - and would have saved both a few headaches.
I also learned how to use colored beans to help kids grasp the concept of adding and subtracting negative and positive numbers. I also learned how using a life size number line helps kids see what is happening, making more sense to them than just doing the problems on paper.
2. What do I
have questions about?
I would like to know more about how and when to introduce which types of problems to students (abstract first vs. concrete first). If you know a particular student learns best in the "concrete," why wouldn't you always use that as a starting point for him/her?
3. What are the
implications for classroom practice?
I can see a lot more students "getting it" when being able to use manipulatives in addition to other forms of problem solving. I loved the algebra tiles and would have loved to spend more time working with them - doing different types of problems because I think I (and students in general) would have a much easier time grasping what what is "happening" within the problem while manipulating the tiles/beans. I think that students would benefit from using manipulatives in many ways. Students would be able to have additional ways of looking at, and solving, problems (more entry points). I also think physically moving the manipulatives around help us (our brains) move the information over from the concrete to the abstract - making a huge difference in what teachers are able to do within the classroom (students would learn more, more quickly, and would be able to move on to different types of problems beginning with the abstract as they would already have the foundation set for those types of problems, etc).
