This interactive online game for one or two players provides practice with number facts and builds strategic thinking and pattern discovery. Players choose an operation (addition, subtraction or multiplication) and 100 problems appear in a 10 by 10 grid. They then select problems that match given target numbers while attempting to get 5 in a row in the grid. Users have the option of working for 3 in a row on a 5 by 5 board, and of turning the sound off. This game is a good balance of skill and luck.

Fact-Tac-Toe By Uncle Bob on 04/19/2012 - 11:08
A game to be enjoyed by those who like number patterns and strategy. To get 5 (or 3) in a row, where should you play first? ... when you have 6 choices that make the target number, which gives you the best chance of winning. The size of the grid allows for many more possible plays and streaks than the usual tic-tac-types. Choose +, - or x.
Good activity, bad graphics By bethb on 01/11/2013 - 15:48
This is a nice activity in concept, but the graphics are not so great. I don't think I would use this activity in this format, I might make a worksheet for it instead.
