Lego Mindstorm Project to Load on robots (includes the 4 programs needed for this activity)
Using a LEGO® MINDSTORMS® EV3 robot and a touch sensor, each group of students inputs a fraction. Then they convert the fraction into a decimal and a percentage using hand calculations, and double check their work using the EV3 robot. They observe the robot moving forward and record the distance it moves. Students learn that the distance moved is a fraction of the full distance, based on the fraction that they input. For instance, if they input ½, the robot moves half of the original distance. Using this information, students work backwards to compute the full distance. Groups then are challenged to move the robot as close as possible to a target distance by inputting a fraction into the EV3 bot. Four different challenges of increasing difficulty are available in this lesson. Most students complete 2 within an hour, but the extra are included for students who master the concepts quickly.
