grade 1 Animals Around Us

Around us live many animals, each in its own place: birds flying in the sky, dogs running on the ground, fish swimming in water and earthworms burrowing underground. Animals can be sorted by where they live, or by how many legs they have. Animals that live in the same place often have bodies suited to moving there, such as wings, fins or legs. Choose sky, ground, water or underground in the picture and the animals that live there stand out.

Where do animals live?

Sky
🌟 Where animals live
①Birds fly in the sky, and dogs and cats walk on the ground
②Fish swim in water, and earthworms dig tunnels and live underground
③Animals that live in the same place often have bodies suited to it: birds in the sky have wings, and fish in water have fins

Sorting by number of legs

Classification

Sorting by number of legs
🐍 Animals without legs
①A snake bends its scaly body to crawl along
②A fish moves its fins and tail to swim
③An earthworm stretches and shrinks its body to move through the soil
🐶 Animals with legs
①Birds, chickens and penguins have 2 legs
②Dogs, cats and rabbits have 4 legs
③Insects such as ants and butterflies have 6 legs
④A spider has 8 legs, so it is not an insect

What animals are good at

🦸 What animals are good at
①Dogs smell far better than people and can find hidden things by smell
②Bats make high sounds that people cannot hear (ultrasound) and find their way by the echoes
③Chameleons can change the color of their bodies
④Eagles see so well that they can spot small animals on the ground from high in the sky

Summary

🎯 Sorting animals
①By where they live, animals can be sorted into sky, ground, water and underground
②By number of legs, they can be sorted into 0, 2, 4, and 6 or more
③Change the rule and the groups change too: penguins and chickens both have 2 legs, but penguins catch their food under water
④Watching animals closely helps you find even more ways to sort them

Examples and Unit Test

Example 1
If you sort a snake, a bird, a dog and an ant by number of legs, how many legs does each have?
1
A snake has no legs, and a bird has 2 legs.
2
A dog has 4 legs, and an ant has 6 legs.
▸ Snake 0 · Bird 2 · Dog 4 · Ant 6
Putting animals with the same number of legs together sorts them into groups, like the sorting table.
Example 2
Where do fish and birds live, and what do they use to move?
1
Fish live in water and swim with their fins and tail.
2
Birds fly in the sky and move with their wings.
▸ Fish: water, fins / Bird: sky, wings
Animals have bodies suited to moving where they live. Choose water and then sky in the picture to compare where the two live.
Unit Test
Which animal has 6 legs?
①Snake
②Dog
③Ant
④Bird
⑤Fish
▸ ③ Ant
1
Snakes and fish have no legs, birds have 2 and dogs have 4.
2
An ant is an insect, so it has 6 legs.
