Classifying Animals
Objective: SWBAT: Classify animals into major groups
vertebrates or invertebrates and their subgroups according to
their physical characteristics.
Big Idea:
Animals are classified into two major groups
vertebrate and invertebrate and then further
sorted into subgroups based on physical
characteristics
Essential Question:
How are animals
classified?
Content Based Vocabulary Words
organism living things / plants or animals
animals organisms that can be made of many
parts and cannot make their own food
vertebrates animals with backbones
invertebrates animals without backbones

Classifying Animals
Essential Question:
How are animals classified?
Animals
Animals are
classified into two
major groups
vertebrate and
invertebrate based
on their physical
characteristics
Vertebrates
Animals with
backbones
Invertebrates
Animals
without
backbones
Vertebrate Animals
• Animals with backbones.
• Other physical characteristics
– a protective skin covering
– an inside skeleton
– blood that circulates through blood vessels
– lungs or gills for breathing.
Vertebrates are divided into five groups
based on physical characteristics.
Vertebrates
Fish
Amphibians
Reptiles
Birds
Mammals
FISH
* body temperature changes with its environment
* breathes with gills
* (most) have scales
and fins
* most lay eggs
AMPHIBIANS
– young lives in water and breathes with gills
– adults breath with lungs on land
– have smooth, moist skin
– most lay eggs
– body temperature changes with its environment
REPTILES
* breath with lungs
* have scales or plates
* most lay eggs
* its body temperature
changes with its environment
BIRDS
* breathes with lungs
* have feathers, a beak,
two wings, and two feet
* lay eggs
* constant body temperature
MAMMALS
* nurse their young with milk
* give birth to live offspring
* constant body temperature
* breathes with lungs
* have fur or hair
Invertebrate Animals
• Animals without backbones.
• Some have outer covering or shell (insects, crabs, or
clams)
• Others don’t have a hard covering or shell (jellyfish
or worms)
• Examples of invertebrates: spiders, shrimp, crayfish,
sponges, sea stars, or snails.

Turn and Talk
• Turn and Talk to a buddy to discuss what
you learned about classifying animals
Guided Practice
Classifying Animals Interactive Game
Vertebrate or Invertebrate
Group Work
• This is a silent thinking game
• Choose a card and hold it up in front of you
• Find a classmate that holds a animal card that is in the
same classification group and subgroup as your animal
• Think about what characteristics your animal has that
makes it a fit in your group
• Turn and Talk with your group to discuss your reasoning
as to why the animals they are grouped together. A
team representatives will share their group conclusions
with the class.
Independent Practice
• Cut animal cards and order them according the
clues given by the teacher guide sheet.
Content Writing From Lesson
Pretend you are a vertebrate animal.
• What animal would you be? Why?
• How are you different than an invertebrate animal?
• Describe your physical characteristics.
• What other category (fish, amphibian, reptile, bird, or
mammal) would you be classified as?
