What you can accomplish together...when you can't see?
Have girls line up next to each other, shoulder to shoulder. Then blindfold them all, and tell them they must rearrange themselves from tallest to shortest.
You can use variations on this, such as lining up in order of birthdays, shoe size or alphabetical order.
Another game to play while students are blindfolded is Pattern Dash. Divide students into teams of four. Give each team a number of shapes cut from poster board, such as a star, circle, square, rectangle and octagon. Have the team members sit side by side at long tables. Call out a pattern, such as square-circle-star-octagon-triangle. Teams must race to lay out the pattern within a certain time limit.
