**Multiplication Patterns**

9 × 1 = 9 | |

9 × 2 = 18 | 1 + 8 = 9 |

9 × 3 = 27 | 2 + 7 = 9 |

9 × 4 = 36 | 3 + 6 = 9 |

9 × 5 = 45 | 4 + 5 = 9 |

9 × __ = __ | __ + __ = __ |

9 × __ = __ | __ + __ = __ |

9 × 8 = __ | __ + __ = __ |

Did you see the pattern in the 9 times table? What numbers are adding up to 9?

The multiplication pattern is explained in the table given below. Ones digit of all the numbers are in descending order i.e. 8, 7, 6, 5, 4, 3, 2, 1. And, the tens digit are the numbers in ascending order i.e. 1, 2, 3, 4, 5, 6, 7, 8. Ones digit number and tens digit number adds to 9.

9 × 1 = 9 | |

9 × 2 = 18 | 1 + 8 = 9 |

9 × 3 = 27 | 2 + 7 = 9 |

9 × 4 = 36 | 3 + 6 = 9 |

9 × 5 = 45 | 4 + 5 = 9 |

9 × 6 = 54 | 5 + 4 = 9 |

9 × 7 = 63 | 6 + 3 = 9 |

9 × 8 = 72 | 7 + 2 = 9 |

9 × 9 = 81 | 8 + 1 = 9 |

Complete the grid by multiplying the numbers

• Mark the numbers 1-10 in the same grid in one colour. • Mark the numbers 12-20 in another colour. • Similarly mark 21-30 in a third colour. Do you see any colour pattern?

No, we cannot see any colour pattern.

Fill this space with your favourite multiplication table.
