Solution:
Using the “Problem Solving Process.
”Fence Post Problem”

1. Understand the problem
1. What data or information is known?
   • Length + 12 yards
     
   • Materials: Post and Rails
   • Distance between posts = 1 yard
2. What data or information is unknown?
   • Number of posts to build a fence.
3. What are the conditions?
   • n>0
2. Make a Plan to solve the problem – (This is known as an Algorithm!)
   • D=distance
   • N=total number of posts
   • D+1=N
3. Carry out the plan.

   12+1=13

4. Reflect on how the problem was solved.

   Remember: any time you have a proble that has a start and end point, add 1 to take into account the starting point.
