Classifying Ocean Animals
Classify ocean animals into major groups: fish (breathe through gills, have scales), marine mammals (breathe air, warm-blooded, feed milk), and invertebrates (no backbone — jellyfish, octopuses, crabs, starfish)
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
If your child saw pictures of a tuna, a seal, and a jellyfish, could they sort them into fish, marine mammals, and invertebrates, and explain what makes each group different?
