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 fivedigit numbers) and multiply (up to three digits by two digits) accurately and efficiently.

Game Elements
 Sprites
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)
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 112
 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
 UPARROW will move sprite up
 DOWNARROW will move sprite down
 RIGHTARROW will move sprite right
 LEFTARROW will move sprite left
 P will pause and resume the game while displaying Rankings
 GamePad
 UPANGLE will move sprite up
 DOWNANGLE will move sprite down
 RIGHTANGLE will move sprite right
 LEFTANGLE 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.

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
