What is the name of the ropes w/ handles for small childrens that teachers use to take kids for walks?

Question

It's a long rope that has loops of different colors for each child to hold in their hand.

Answer 1

a guide rope or a walking line,

a word of advice if you're planning on getting one for your daycare/class/multiples, get one where all the handles are the SAME color, otherwise everyone will fight over who gets the "good" colors or some poor little boy will get stuck with pink or purple and throw a fit.
