These little ghosts are going trick-or-treating. Can you draw a line that touches every house exactly once and ends up back where it started? The line can’t cross itself, can’t go diagonally, and has to touch the houses in this order: large-medium-small-large-medium-sma ll. Along the way you’ll collect SOME of the candies in your bags. Only count the candies in your path! *To make a series of straight lines, go to Insert>Shapes> line.
