DUE WEDNESDAY

Multi-paths
Find the number of pathways from one corner of each grid to the other. Remember the rules: no extra movement, or backtracking. Move toward “home” and not in circles. The first grid is a 1 x 3 grid. The second is a 3 x 4. Show all your evidence. Are there any patterns you can observe? Is there a method that might work on ANY grid?
