                                 to learn about:

                                           Number Pyramid                     Number Grid
                                            Directions



                  In this chapter,  we  will learn  how  to  use reasoning  to  think  clearly  and  solve
                  problems. We will also explore how analysis helps us understand things better by
                  breaking them down into smaller parts.

                      NUMBER PYRAMID


                  In number pyramid, the number in each space is the sum of the two numbers
                  below it.
                       Start with a circle, which has two filled adjoining circles below it.

                       Blue circle will be the sum of two green circles.





                                                                                        9

                                                                                     5      4


                                                                                 3      2      2


                                     2     1      1      1                    2      1      1      1


                       Therefore, blue circle will be 2 + 1 = 3.

                       We will get the remaining numbers by following the same pattern.


                                    What if you could use computer to create secret codes that only your
                                    friends could decode? What would your code say, and how would you
                                    use it to communicate?
