Chapter 9 — Utsav

Chapter 9 of the Class 1 Maths NCERT textbook (Joyful Mathematics), "Utsav", introduces young children to recognising, extending, and creating patterns through festival-themed activities using colours, numbers, shapes, and everyday objects.

• Festivals and Patterns Around Us — The chapter opens with the festival of Uttarayan — celebrated as Makar Sankranti, Pongal, Bihu, and Lohri — to show how shapes and patterns appear in everyday celebrations. Children are encouraged to discuss local festivals and spot patterns in the things they see during those celebrations.
• Extending Visual Patterns — Children look at a series of patterns (labelled A through H) and practise drawing the next elements to continue each one. Using concrete objects alongside drawing helps children understand how a pattern repeats and grows.
• Making Patterns with Colours and Prints — A story about Munna — who makes a pattern using thumb and finger impressions — invites children to create their own fingerprint patterns. The activity also asks children what colour should come after pink in a colour pattern, encouraging them to explain their reasoning.
• Number Patterns — Children study rows of numbers that follow a pattern and fill in the missing numbers. This links the idea of repeating or growing sequences to early number sense.
• Kolam, Rangoli, and Project Activities — Children complete a kolam or rangoli pattern helping Murthy and Vani. Project Work extends the chapter by asking children to arrange pebbles, leaves, coins, and other objects into patterns, observe patterns in nature (butterfly wings, animal skins, beehive), and even create action patterns using clapping, snapping, and stamping.

1. 01Uttarayan festivals like Makar Sankranti, Pongal, Bihu, and Lohri mark the transition from winter to summer and inspire the chapter's pattern theme.
2. 02Children extend eight different visual patterns (A–H) by drawing the next elements.
3. 03Munna's fingerprint pattern activity lets children create their own repeating colour pattern using thumb and finger impressions.
4. 04Children decide which colour comes after pink in a sequence and explain why.
5. 05Vegetable slice printing is suggested as a hands-on way to make patterns.
6. 06Missing numbers in number patterns must be identified and filled in.
7. 07Project Work asks children to find patterns in nature — leaves, butterfly wings, animal skin, and tiles — and in art forms like dance and textiles.
