                   Writing multiplication facts
                   •  Place 4 sticks vertically.
                   •  Now, put one stick horizontally across them. Here, we get 4 points of
                      intersection.
                     Thus, 4 × 1 = 4.
                   •  Put one more stick horizontally. Count the points of intersection. There
                      are 8 points of intersection.
                     So, 4 + 4 = 8  or  4 × 2 = 8.
                   •  Now, put one more stick horizontally and count the points of intersection.
                      There are 12 points of intersection.
                     So, 4 + 4 + 4 = 12  or  4 × 3 = 12.
                   •  Continue in the same way and write at least 10 multiplication facts.
