Part A-Description of a Need-Wicked Problem Project

The problem:
At my current school we use a very experiential mathematics curriculum (Investigations by TERC) which is perfect for the younger grades, but not as comprehensive for the upper elementary grades. The curriculum is based on a lot of games, group activities and not a lot of actual pencil and paper. It is a great program, however, the transfer from elementary to Middle School, especially in math, can be traumatic for some students as they use a more conventional curriculum. It is not only the transition between schools, it also the fact that the curriculum comes with no resources for implementing any sort of differentiation within the math class for either high or low students. It also does not provide any sort of extra work in case students are struggling with a certain process. While I am at it, I certainly would not mind making math fun by adding some gaming into the equation (see the Ted videos embedded at the end of this post.)
How will technology help?
In general right now we differentiate using the copy machine. We make copies, and then more copies, we assign extra work, give homework, and gather small groups. However I believe with technology it would make a big difference to my different levels of student. I believe especially it would be great to come up with some self study programs for the higher level students who are motivated to continue their mathematics on their own. If I can find some internet based games, programs and/or downloadable programs that can be individualized and teach higher level skills to allow the students to take their futures into their own hands.
What is the scope?

I am hoping to find, review and test at least four different programs for the students. The time the students spend on each program will depend on the scope of the program (Does it focus on one mathematical principle or many?) I will have my students who finish their math early use it, and I will assign as homework for a few students instead of the regular math homework.
Relevant research and resources

I will be using several resources. Aside from general internet searches I will use our Professional Development Library (Mathematics Teacher Magazine), Cool Tools for Schools and our school belongs to the National Council of Teachers of Mathematics (NCTM) where I can research their databases.
I plan on adding a web page to my current classroom website that will contain the listing of the resources for the students. I also plan to poll my students when they are using a specific program to see what they like about it and what they do not so I can compare the different tools that I find.

Indicators of a successful project

A recommendation for my fifth grade team and a list of resources that can aid us with implementing a better program for differentiation in math. What will it look like? At first just a website, hopefully ranked by my students, that lists resources as they are found and contains a precise descritption for the user before they choose which resource they will use (if they have not been assigned).
