Activity 01
Egg or Baby? Picture Sort
Provide students with a set of animal picture cards. They have to sort the pictures into two piles: 'Lays Eggs' and 'Gives Birth to Babies' on a chart paper.
Identify an animal that lays eggs.
Facilitation TipUse pictures of common Indian animals like cows, sparrows, snakes, and goats to make it relatable.
What to look forShow pictures of various animals and ask students to give a thumbs-up for animals that give birth and a thumbs-down for those that lay eggs.

Activity 02
Animal Family Match-Up
Create a worksheet with two columns, one with pictures of adult animals and the other with their babies (e.g., dog and puppy, hen and chick). Students have to draw lines to match the parent with its baby.
Compare how a bird has babies with how a cat has babies.
Facilitation TipInclude some tricky ones like a frog and tadpole to spark curiosity and discussion.
What to look forA simple worksheet with two columns, 'Lays Eggs' and 'Gives Birth'. Students write the names of animals from a given list into the correct column.

Activity 03
Clay Modelling: An Egg and a Baby
Give students modelling clay to create two things: an egg and a baby animal that does not come from an egg, like a puppy. This tactile activity helps reinforce the two different modes of birth.
Explain what a mammal is.
Facilitation TipEncourage them to explain their models to their partner, describing which animal lays the egg they made.
What to look forAsk students to draw one animal that lays eggs and one that gives birth, and label them. This shows their own confidence and understanding.

Start with a picture talk, showing a cat with kittens and a bird with eggs. Use a simple T-chart on the board to classify animals as students name them. Emphasise the visible clues: animals with external ears and hair usually give birth, while those without often lay eggs. Keep the language simple and use lots of local examples.
By the end of this topic, you will be able to sort animals into two groups: those that lay eggs and those that give birth to babies, and you will know what makes an animal a mammal.
Watch Out for These Misconceptions
Only birds lay eggs.
Many other animals also lay eggs. For example, snakes, lizards, frogs, fish, and insects like butterflies all start their life from an egg.
All animals that live in water lay eggs.
While many fish and amphibians lay eggs, some water animals like dolphins and whales are mammals and give birth to live babies.
All big animals give birth to babies and all small animals lay eggs.
The size of an animal does not decide how its baby is born. A very large bird like an ostrich lays eggs, while a small animal like a mouse gives birth to babies.
