Last year I wrote about learning fractions with Legos. To turn this activity into a math station, I made a Lego Rollgame. Kids roll a die to determine what color comes next for their fraction tower. After ten rolls, have kids figure out their fractions for each color. Another Lego math station idea is to write fractions on notecards and have children create the fraction out of Legos (like a fraction museum). Once they've built all of their towers, they can call the teacher over to check.
