Flash cards were pretty good math practice. But, they were always the same math problems, over and over. Lo and behold, JavaScript to the rescue! Just select the difficulty level then click the type of problem you want to practice with, (add, subtract, multiply, and divide) and JavaScript will give you a problem. And, a built-in score checker grades you along the way!

Great practice for elementary-aged students just learning their math skills, or for anyone wishing to practice a bit!

Your goal in Five-in-a-row is to get five X's in a row while preventing your opponent from getting five O's in a row. In this JavaScript implementation, the game is played on a 15x15 board. (If you'd like a bigger or smaller board, you can set it to any size from 10x10 through 20x20.) You play X's, and the computer plays O's. First move is yours. Enjoy!
