Project Based Learning

I have been looking at implementing Project-based learning the past year.  I wanted to do a full chapter or section that implemented project based learning, but felt that Algebra 2 is difficult for students, but I think I found the solution.

The project that I have had the past few years is students create their own dice (2 years ago) and 3D print their own dice and find the theoretical and experimental probability (Last year).  I thought this was a good end of the chapter project.  

Now I want to make this my project based learning chapter.

Key Knowledge, Understanding, and Success Skills

I want students to work in groups of 4 and use collaboration skills for them to work on the project together.  The standards that they will cover (using the Nebraska Math Standards):

MA 11.4.1 Representations: Students create displays that represent data.

MA 11.4.2 Analysis and Applications: Students will analyze data to address the situation.

MA 11.4.3 Probability: Students will interpret and apply concepts of probability.

Challenging Problem or Question

The students challenging problem is to create a new dice for a nearby casino and find a dice where the "house" wins over 50% of the time, but not more than 60%. Students are to create a presentation with their dice and their data to a selection of students and teachers. Students will share with other students their presentation and questions.  Students will have a chance to critique and revise before doing their final presentation.

The problem I am having is making their learning public.  How can students take their learning global?
