# **Rainbow Colours Name for Class 1 Maths**

After the rain, we can see the rainbow colours passing between the clouds in geometrical shapes called semicircles. Here the students will learn how mathematical topics like ordinal numbers and counting numbers are related to rainbows. The application of addition and subtraction of numbers is also explained here in a very colourful way. This discussion will clarify the child’s query about the **rainbow colours name** for class 1 and how many colours are in a rainbow.

## How Are Rainbows Formed?

A rainbow is formed in the sky soon after rain. In the rainy season, we see a rainbow. A rainbow is an arc which has multicolours. ‘Arc’ means a part of the circle.

We can see a semicircle rainbow on the ground, but if we look at it from an aeroplane, we can see it in a complete circle.

In the rainy season, water drops break the Sun’s light into seven colours, and that’s why we see the rainbow in the sky when the rain and the Sun co-occur.

**What Colours Are in the Rainbow?**

There are total of 7 colours in a rainbow. The sequence/order of the colours is always the same as the following –

**Order of Colours in the Rainbow** (Top to bottom)

No. | Colour Name | Colour |
---|---|---|

1st | Red | |

2nd | Orange | |

3rd | Yellow | |

4th | Green | |

5th | Blue | |

6th | Indigo | |

Whenever it’s raining, look out for the beautiful rainbow!!!

### Answer 2:

Complete the table of the numbers 1 – 100 . Give the colour according to the number in each box.

## Question 3:

Count Each Number of Boxes in the Above Chart. And Answer the Following Questions.

Colour | Numbers |
---|---|

Red | 1, 2, 3, 8, 9, 10, 11, 12, 19, 20, 21, 30 |

Orange | |

Yellow | |

Green | |

- How Many Total Boxes Are There in the Above Number Chart?
- What Colour Boxes Are the Most?
- What Colour Boxes Are the Least?
- How Many Are More Green Boxes There Than Red?
- How Many Least Indigo Colour Boxes Are There Than Blue?

### Answer 3:

Count each number of boxes in the above chart. And answer the following questions.

Colour | Numbers |
---|---|

Red | 12 |

Orange | 10 |

Yellow | 20 |

Green | 18 |

Blue | 16 |

Indigo | 14 |

Violet | 10 |

- There are 100 boxes in the above number chart.
- Yellow colour boxes are most. 20 is the largest number, and there are 20 yellow boxes in the number chart.
- 10 is the smallest number. And there are 100 orange and violet boxes in the number chart. Orange and violet colour boxes are the least.
- Number of green boxes = 18

Number of red boxes = 12

Number of more green boxes than red = 18 – 12 = 6 - Number of indigo boxes = 14

Number of blue boxes = 16

Number of less indigo boxes than blue = 16 – 14 = 2
