One of the issues with Pygame is its barrier to entry but it has great benefits in given kids something visual to play with which has its own intrinsic motivation. This is a link to all the files I will be using tonight as well as my notes (probably to be added later) on each step and where the pitfalls are.
Clearly, if you are an experienced programmer and familiar with objects, there are much better ways to design games but this project is scoped first and foremost to teach the bare minimum to get the kids going.

Steps to build the game in code (steps in text coming)
Step 1: a screen
#import stuff
import pygame
#setup screen
pygame.init()
screen = pygame.display.set_mode((640, 480))
#screen.fill((255, 255, 255))
#pygame.display.flip()
#setup vars and files
#instructions
#keeping track of cards
#managing time
#main loop
#check time passed (slow computer down)
#if there is a snap event
#increase score and print outcome
#update screen and pause
#reset time_delay, update previous_card and get new card
#update screen
#check for events
#if the quit button was pressed
#else if there was a keypress (any keypress)
#check if card matches
#increase score and print outcome
#update screen with outcome and pause
#reset time delay, update previous_card and get new card
#update screen
import pygame
#setup screen
pygame.init()
screen = pygame.display.set_mode((640, 480))
#screen.fill((255, 255, 255))
#pygame.display.flip()
#setup vars and files
#instructions
#keeping track of cards
#managing time
#main loop
#check time passed (slow computer down)
#if there is a snap event
#increase score and print outcome
#update screen and pause
#reset time_delay, update previous_card and get new card
#update screen
#check for events
#if the quit button was pressed
#else if there was a keypress (any keypress)
#check if card matches
#increase score and print outcome
#update screen with outcome and pause
#reset time delay, update previous_card and get new card
#update screen
Step 2: quitting
