Controls and Output

• This activity is similar to Connect Four, and is designed for two players. The goal is to have four pieces of the same color connected either horizontally, vertically, or diagonally. One player uses red pieces, while the other player uses blue pieces. To earn a piece, you need to answer a fraction-related question by entering it into the answer textbox:
  

• Note that within the input field there is a pattern(#/# or ####) which indicates whether your answer should be a fraction or a decimal. If your answer is a fraction, it must be in lowest terms. If it is a decimal, it must be accurate to within .001.
• After you have entered your answer, you need to click on the Answer button to find out if you are correct.
  

• If a player answers their question correctly, they will be able to place one of their pieces on the board. To place a piece, simply click on the column that you want to drop the piece into. The piece will appear in the lowest available slot in the column. If a player answers incorrectly, the other player will be asked to answer the question. If they also incorrectly, the answer will be displayed in a pop-up frame and a new question will be asked to the original player:
