My name is Denny Rowell and I am looking forward to participating online with the ToolFest at Drexel the next couple of days. I am an algebra and prealgebra teacher at Jay County High School in Portland, Indiana. I am just ready to start my third year of teaching. I received my training in teaching in the early seventies, but returned to the classroom as a teacher after being involved in dairy farming for 28 years. I enjoy teaching and am learning all I can. I have always been aggressive but conservative in my management style. I am not afraid of change, but am not interested in doing things just because they are new. I am currently about 2/3 through my MEd. in education at Indiana Wesleyan University, Marion, Indiana. I thing many of the tools at Math Tools could be real helpful to my students.
My Web site is here: http://online.indwes.edu/medol24/dennis.rowell/
Here are four tools I could use with my students:
The first is showing binomial multiplication using algebra tools as found at http://matti.usu.edu/nlvm/nav/frames_asid_189_g_4_t_2.html?open=activities. This series of eight activities accurately showed what happens when one multiplies one binomial by another.
The manipulative on figuring the percent if we know two of the three: part, whole or percent as found at http://matti.usu.edu/nlvm/nav/frames_asid_160_g_3_t_1.html?open=teacher would be great for my 9th grade pre-algebra students.
Graphing for both my algebra and prealgebra would be facilitated by the students spending some time with the graphing tool at http://matti.usu.edu/nlvm/nav/frames_asid_109_g_3_t_1.html.
The factor tree at http://matti.usu.edu/nlvm/nav/frames_asid_202_g_3_t_1.html?open=teacher is an awesome tool to help my students with finding the GCF and the LCM.
