Personal Concerns and Next Steps

I have some personal concerns about they way to use the constructivism approach in the classroom. This is a hard considering in the past I was taught to find the "right" answer. I do have some concerns with finding what is a good manipulative to use in the classroom considering that some of the mainpulatives that I grew up using weren't the best tool for learning. This approach does make sense in teaching math and gives students the chance to figure out the problems than rather having the answer given to them. For the next steps in my classroom I want to try and use the constructivism approach in my classroom so my students can actually learn for themselves. I think if I have a few lesson plans that are more toward this way I will have a good start. I want to find appropriate manipulatives that can help my students have more of a visual concept and understanding of a math idea.
