Fourth grade level math game based on the classic arcade game PacMan
PacMath

Last updated February 25, 2010

Introduction

PacMath is an educational math game based off the well-known 80's arcade game PacMan. In addition to the original game mechanics, PacMath will add fourth grade level math to this fun and exciting arcade game in order to make learning fun. PacMath will provide the student with different type math 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 PacMath is to use the basic mechanics of the 80's arcade game PacMan to teach fourth grade math skills. Currently, PacMath randomly generates questions using the four basic arithmetic functions (add, subtract, multiply, divide), up through the 12 times tables. In the future, we hope to build in functionality that will allow teachers to generate their own custom questions which will allow them to tailor PacMath to their curriculum.

Education

Media: PacMath_Lesson_Plan.doc

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.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.
  • 4.N.13 - Divide up to a three-digit whole number with a single-digit divisor (with or without remainders) accurately and efficiently. Interpret any remainders

How It Works

Media: PacMath_User_Manual.doc

  • One Player
  • Board Setup like the Original Arcade Game
  • Question Appears (3 per level)
    • If the player eats a Power Pellet (4 per level) the ghosts freeze for a few seconds
    • Player has to eat the Enemy with the correct answer
    • If the player eats the wrong answer they lose a life, and continue playing, the ghost is warped back to its spawn point
    • If the player eats 100 regular pellets they gain a life
      • A life is an answer attempt, if you run out of lives the game ends
    • After the three ghosts have been eaten and answered correctly, a new 'level' (so to speak) begins
      • At the start of each level, three questions are generated of random operation type (+, -, /, x)
  • Questions
    • Random question generation
    • The answer has a programmable limit (12 by default)
    • Current Types
      • Multiplication tables
      • Division tables
      • Addition tables
      • Subtraction tables
    • Future Types
      • Order of operations
      • Inequalities (given a number, find which ghost's answer is greater than or less than the number)
      • Basic Algebra problems (solve for x)
      • Fractions

Features

  • PacMath
    • User will control a yellow sprite
    • User will attempt to "eat" numbered sprites based on mathematical questions
  • Question sets
    • Question type randomly generated at game start
  • Future Features
    • Instructor will be able to see the rankings of a particular student
    • Student or teacher will be able to choose question type
    • Top 10 scores will be recorded and displayed while game is paused
    • Adjustable speed (faster for more of a challenge)

Controls

User will be able to interact with the game through the keyboard

  • 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
  • Future Controls - GameBoy mode
    • 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

Bugs/Todo

  • Game size is not the proper size for the XO (too small)
    • Potential Fix: Increase block size from 25px to 33px
      • Grid stays 25x25, each point on the grid is 33x33
      • Right hand answer frame increases to 375px in width (from 275px)
      • Bottom question frame stays 75px in height
  • Support input via alternate controls while in ebook mode
    • Directional angles and square button to pause
  • Permanent Documentation solution is required
    • non-personal site
    • run epydoc nightly for up-to-date documentation

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. It would be very desirable if you would perform the gettext internationalization (i18n) that is needed 
to get this set up in Pootle for localization into other languages (i.e. generate POT file, set po directory in git repo,  
make user:pootle a committer, file Trac bug with component = localization requesting Pootle hosting, etc.).

I would recommend you look at how other pygame-based activities are
packaged. For example, Maze.

Tomeu Vizoso (February 12, 2010)

Also, Jim's book could help clarifying several concepts, though I
don't see anything specific to pygame/sugargame.

Jim Simmons (February 12, 2010)

There is a project in Gitorious that sounds like it might be of use to you:
http://git.sugarlabs.org/projects/sugargame
I haven't tried it myself, but the description sounds promising.
