                       4.  Fill in the blanks by observing the pattern:
                           a.  37 × 3 × 1 = 111                                b.  5 × 5 = 25

                               37 × 3 × 2 = 222                                    55 × 5 = 275

                               37 × 3 × 3 = _____                                   ____ × 5 = 2775

                               37 × 3 × 4 = 444                                    5555 × ____ = 27775

                               37 × 3 × ____ = 555                                 55555 × 5 = _______

                         A figure is said to be symmetrical if it can be folded along an imaginary line to form
                          two halves that fit exactly over each other. This imaginary line is called the line of
                          symmetry.
                         Symmetry focuses on line symmetry (or mirror symmetry), where a shape can be
                          folded along a line so that both halves match exactly. The line of the fold is called
                          the line of symmetry.
                         A reflection is like a mirror image. The figure does not change on reflection. The only
                          change is in the orientation.
                         A pattern is a sequence or arrangement of shapes, figures, or numbers in a certain
                          order.
                         Tessellation or tiling is a pattern of geometric shapes that fit together perfectly or fill
                          a 2D space without any gaps or overlaps.
