Flash Action Addition & Subtraction transforms your computer into a fast, fun, fact machine that makes learning addition and subtraction child's play. Children practice problems against the clock, challenge another player to a game of fast facts or test themselves for speed and accuracy. Set the program to practice addition, subtraction or mixed problems, and the difficulty will be adjusted based on your child's score. Children can check their facts in the handy chart or print the chart for reference away from the computer. Learning is reinforced with a printed scorecard that reports progress and shows problems to practice. Audio guidance, colorful graphics, animated rewards, and positive reinforcement motivate learning.
