# PacMath

## Introduction

PacMath is an educational game based off the well known 80's arcade game PacMan. Using the original game concept PacMath will add fourth grade level math to the fun and exciting game of PacMan in order to make learning fun. The game will provide the student with different problems and in order to solve the problem correctly the student will have to eat the ghost with the correct answer.

### Sketch Up

## Objective

The objective of this project is to incorporate the teachings of fourth grade mathematics to students through PacMath, a fun, interactive, mathematical game based on the 1980's PacMan. One of our main objectives is making PacMath flexible where the teacher will be allowed to create its own group of questions and not be forced to use only a set group of questions. This would allow more flexibility in the learning plan for the teacher.

## Education

Current Standards to be addressed with in this project:

(As per standards of the Massachusetts Department of Education)

- 4.N.2 - Represent, order, and compare large numbers (to at least 100,000) using various forms, including expanded notation, e.g., 853 = 8 x 100 + 5 x 10 + 3.
- 4.N.8 - Select, use, and explain various meanings and models of multiplication and division of whole numbers. Understand and use the inverse relationship between the two operations.
- 4.N.9 - Select, use, and explain the commutative, associative, and identity properties of operations on whole numbers in problem situations, e.g., 37 x 46 = 46 x 37, (5 x 7) x 2 = 5 x (7 x 2).
- 4.N.11 - Know multiplication facts through 12 x 12 and related division facts. Use these facts to solve related multiplication problems and compute related problems, e.g., 3 x 5 is related to 30 x 50, 300 x 5, and 30 x 500.
- 4.N.12 - Add and subtract (up to five-digit numbers) and multiply (up to three digits by two digits) accurately and efficiently.

## Game Elements

- Sprites

(May change due to copyrights)

## How It Works

- One Player
- Board Setup like the Original PacMan (one Maze to start off)
- If the player eats a Power Pellet (4 per level)
- Question Appears (4 per level -> 1 per Power Pellet)
- After the four Power Pellets have been eaten and answer correctly a new 'level' (so to speak) begins
- Player has to eat the Ghost with the correct answer (answers will be displayed on the ghosts throughout the entire 'level'
- If the player eats the wrong answer they return to the center of the maze and continue playing
- If the player eats 100 (may change) regular pellets they gain a life

- Questions
- Some default ones to start off with (come with the activity)
- GUI/Prompt for the teacher to input their own questions, saves as an XML (the activity will load the file)
- The answer will have a digit limit (thinking 3 digits)

### Features

- PacMath
- User will control a yellow sprite
- User will attempt to touch numbered sprites based on mathematical questions

- Difficulty settings
- EASY - slower game speed / easy difficulty questions
- NORMAL - average game speed / easy and average difficulty questions
- HARD - fast game speed / easy, average and hard difficulty questions
- PRODUCT MADNESS - fast game speed / only multiplication tables from 1-12

- Questions
- Instructor will be able to alter the questions the students will have to answer
- Instructor will be able to see the rankings of a particular student

- Ranking
- Top 10 scores will be recorded and displayed while game is paused

### Controls

User will be able to interact with the game through two input devices

- Keyboard
- UP-ARROW will move sprite up
- DOWN-ARROW will move sprite down
- RIGHT-ARROW will move sprite right
- LEFT-ARROW will move sprite left
- P will pause and resume the game while displaying Rankings

- Game-Pad
- UP-ANGLE will move sprite up
- DOWN-ANGLE will move sprite down
- RIGHT-ANGLE will move sprite right
- LEFT-ANGLE will move sprite left
- SQUARE will pause and resume the game while displaying Rankings

## Code Structure Plan

We will be using a mix and match of two existing PacMan games implemented in Python. The first one is from Berkeley.edu and it is a very simple implementation. The second PacMan comes from PyGames and it is more complicated in its design and implementation. We will be using a bit of both to try to come up with an optimal one that would work at a good speed in the XO.

- Questions (default question list provided)
- Maze (single maze to start)
- Player
- Enemies
- Game (control)
- Activity (main)
- Setup (for loading on the XO)

## Development

The code for this project is located at the Git.SugarLabs.org repositories. The project is still on initial planning stages and thus there is no code to work on yet.

The current group of people working on the development are:

- Yasser Hernandez, email: yah3133 [at] rit.edu
- Taylor Plimpton, email: tjp3947 [at] rit.edu
- Abel Rendon Jr, email: axr9780 [at] rit.edu
- Dennis Rodriguez, email: dxr4305 [at] rit.edu

## Milestones

- Week 2 ( January 15th 2010 - January 22nd 2010 )
~~Get git working on git.sugarlabs.org~~~~Finish adding details to the PacMath Wiki~~~~Make a Sketch-Up for the game~~~~E-mail Math4 Mailing List informing everyone about our project and ask for ideas and volunteers~~

- Week 3 ( January 22nd 2010 - January 29th 2010 )
- Get all the code sections defined well
- Split up code sections
- Start initial basic coding
- Test an initial simple blank screen

- Week 4 ( January 29th 2010 - February 5th 2010 )
- Test the basic activity

- The PacMath sketches look great, can't wait to give it a play through :-)

Regarding questions/game settings, make sure you have a play of Walter's VisualMatch activity and see how the toolbar provides lots of flexibility to the game challenge type. It would seem like a good approach to let the user choose the starting case (perhaps via a teachers verbal guidance in class) and then have the general math difficulty level increase as they complete level to level.
