Practice of addition/subtraction using pictures. Author: Abhay B. Joshi (abjoshi@yahoo.com) Instructions: 1. Click on the “Green flag” and read the instructions. 2. Perform as many additions/subtractions as you can until the timer expires. 3. The program will announce your points and stop. Notes: This is a simple program that allows a preschooler practice adding or subtracting single digit numbers. Basically, it presents 2 numbers in countable picture form and asks how much they sum or difference is. The user needs to perform as many operations as possible in 30 seconds. At the end the program presents the how many were right and wrong. If you want to understand how I designed this program, please refer to my book: "Adventures in Snap Programming" available on Amazon.com
