Description of the Activity:
The purpose of this task is for students to solve a problem involving distances between objects whose positions are defined relative to a specified location and to see how this kind of situation can be represented with signed numbers.
A full solution requires systematic listing of pairs of houses, a valid list of differences – either subtracting the smaller number from the larger, or taking absolute value of difference in any order – as well as computations which could be done by counting on the number line or subtracting fractions.
