Project Reflection (Board Game)

In Math class, for the week or two, we have been working on a "Electronic Board Game". We had to incorporate math terms we learned (like Ohm's Law) and make circuitries for this game. Read more below for detailed description.

Project Description
This is the Electronic Board Game project in the 9th grade Math class of Mele Sato. In this project, we learned many types of math terms, ranging from Ohm's Law to the charge of an electron. Because we are in High Tech Village, we are required to put our knowledge to use, make a board game using Circuitries and math laws. Throughout this project, we mastered how to calculate the charge of an atom, figure out the current in a circuit, and see how much resistance certain objects give off.

Examples of work/pictures
My partner Shaelyn Washburn had the privilege and the time to make a page with our pictures/work. Here's a link to it.

Reflection Questions
  1. How has drafting and revising helped make your project a success?
    Its the basic concept of "the customer is always right". We take any advice we get, and then redo our project to fit the needs of the people. This way, we can make an enjoyable game and still meets the standards of ourselves.
  2. In what ways did communications help or hurt your project?
    In a way, it helped us. Sure, all we did was "Okay, I do this, you do that, you work on the other". But when we needed, we had output on criticizing each other to improve on our work.
  3. What have you done so far to make your board a success?
    I made the rules and the circuitries work. At first, the rules were long and complex (see Rules) because I based the rules off of actual rules. If you look at "Monopoly" or "Guess Who?", the rulebook look the same as I have done our rules... except everyone wanted the simple "User-friendly" version. Frustrating, no? ¬_¬
    I've work with computers and various circuits in the past, so theorizing and creation of our circuit (and assistance of other people's circuits) was easily accomplished. Most are parallel circuits, which would confuse a lot of people at first, but you'd get used to it after a while. In a sense, a Parallel circuit is a bunch of Series circuits bunched up together.
  4. What would you do differently if you could do it again?
    I don't know. I could've made the game a bit more fast paced, but that defeats the whole purpose of a Board game, right?
Thats it for the reflection. This is Andy, signing off
