Chapter 9: Utsav

Introduction

"Utsav" means festival. This chapter uses the colours and decorations of Indian festivals to teach patterns. The book begins with the harvest festivals of Uttarayan – Makar Sankranti, Pongal, Bihu and Lohri – which, according to the Indian calendar, mark the change from winter towards summer, the return of sunny days and the start of the harvest season. The festival picture is full of shapes and repeating designs that children can spot, talk about and continue.

What's in this Chapter

Festival picture: Children discuss the local festivals they celebrate with their families and look for the shapes and patterns in the decorations, kites, lamps and rangoli.

Extend the patterns: Eight patterns (A to H) made of shapes and colours are shown; children continue each one by drawing further.

Let us Do – Munna's fingerprint pattern: Munna, who loves colouring, makes a pattern with the impressions of his thumb and fingers. Children make their own fingerprint pattern and discuss, "What colour should come after pink and why?"

Vegetable prints: With an adult's help, children cut slices of vegetables and use them as stamps to make patterns.

Look at the patterns and extend them by colouring, and complete the pattern.

Number patterns: Study the pattern and fill in the missing numbers.

Kolam: Murthy and Vani help their Amma make a kolam (rangoli); children complete it.

Project Work:

- Arrange pebbles, flowers, leaves, glasses, bowls, sticks, bangles, coins and caps in patterns, including jewellery and floral designs.

- Observe patterns in nature – leaves, butterflies, the skins of cats, dogs, zebras and tigers, curtains, sarees, dupattas, tiles and beehives.

- Make a collage from objects found around you.

- Create action patterns with clapping, snapping fingers and stamping feet.

Key Ideas

A pattern is something that repeats in a regular way.

To extend a pattern, find the part that repeats (for example, a repeating order of colours or shapes) and continue it.

Patterns can be made with colours, shapes, objects, numbers, sounds and actions.

Patterns are all around us – in nature, clothes, buildings and art.

India has a rich heritage of patterns in temples, mosques, churches, gurudwaras, monuments, dance and art forms.

Words to Learn

pattern – a design that repeats (प्रतिरूप / पैटर्न)

repeat – do again and again (दोहराना)

extend – continue further (आगे बढ़ाना)

festival – a special day of celebration (त्योहार / उत्सव)

harvest – gathering ripe crops (फसल की कटाई)

kolam / rangoli – floor designs made with powder (कोलम / रंगोली)

fingerprint – the mark made by a fingertip (उँगली की छाप)

collage – a picture made by sticking many things together (कोलाज)

Tips for Parents & Teachers

During festivals, point out patterns in rangoli, lamps, kites and clothes.

Make a pattern with spoons and forks on the table and ask, "What comes next?"

Let the child clap a pattern and copy it back to them.

Take a nature walk to find patterns on leaves, flowers and animals.

Use vegetable slices (ladyfinger, onion, potato) as stamps – an adult must do the cutting.

Common Mistakes

Copying only the last item instead of the whole repeating part.

Changing the order of colours midway.

Thinking a design is a pattern even when nothing repeats in a regular way.

💡 Key Learning Points

✓Recognise patterns in festivals, nature and everyday objects.
✓Identify the repeating part of a pattern and extend it.
✓Create patterns using colours, fingerprints, vegetable prints and objects.
✓Complete simple number patterns.
✓Make action patterns with claps, snaps and stamps.

👨‍🏫 Teaching Tips

→Start by discussing local festivals and the patterns seen in their decorations.
→Use concrete objects (beads, seeds, bangles) to make patterns before drawing, as the book advises.
→Ask children why a particular colour comes next, to build reasoning.
→Organise a vegetable-print session with adult help for cutting.
→Invite children to share rangoli or kolam designs from home.
→Take children on a pattern walk to find patterns in nature and buildings.
→Use clap–snap–stamp sequences as warm-up activities.

📋 Assessment Questions
