Explanation/Summary:

On the carpet, the teacher will make a number line out of tape. Then at every notch, she will put whiteboards with numbers 0 to 100 counting by 10’s. Then, she will allow one student to be the “driver” and he has to start at 0. The teacher will tell the student to drive down the number line like he would be driving somewhere on the highway. Every whiteboard with numbers are the exit numbers of the highway. As they continue to drive, the teacher will tell the student to stop at 27 and then ask students, “If you had to use the restroom and there are restrooms on every exit, which exit would you go to in order to use the restroom? Which is the closest?”
