The rules are simple (kind of like the "24" game):
1. Choose 5 common fractions, with denominators of halves, thirds, fourths, sixths, eighths, tenths and twelfths.
2. Students add, subtract, multiply, and/or divide the fractions to make the 5 fractions equal the target number of 1.
3. Students can receive points for meeting the target number of 1. If they do so using only 3 numbers, they get 300 pts; 4 numbers = 400 pts; all 5 numbers = 1,000 pts....you can set up the point system any way you'd like.
We're going to try it a few days next week, after we finish all the operations, and since I have my fraction cards, I'll just hang them on the board:
For this particular set of fractions, I found that 3/4 x 2/3 = 1/2 + /2 = 1; that uses only 3 fractions, so I'd get 300 points.
2/3 + 2/6 = 1, but that's only 2 fractions. I may consider giving points for using just 2 fractions though, until they get the hang of the game.
Can you make the 5 fractions equal 1?
