# 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.

## 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
• Names and maybe their picture

## 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 DIE!!!
• 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)

## Code Structure Plan

• Questions (default question list provided)
• Maze (single maze to start)
• Player
• Enemies
• Game (control)
• Activity (main)

## 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:

## 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 5h 2010 )
