1. Arrange the objects in the shape of a triangle, as show.

2. The challenge is to make the triangle point is the opposite direction. You can move only three of the objects.

Answer:

Doing it:
The following letters are in a logical sequence : o, t, t, f, f, s
Can you figure out the pattern?
What are the next four letters?

Answer
The missing letters are s, e, n, t.

Story behind the activity:

One way to solve a problem is simply to jump in and start trying things. This is called trial and error. The approach isn't bad, if you get a solution before you get frustrated. A better strategy for solving the coin problem is to think about where you want to end up -- and work backwards from there.
