Mammal vs Reptile Sort – Picture Worksheet

Reptile or Mammal? provides a two-category classification supported by short trait reminders. The page states that mammals have fur or hair and breathe air, while reptiles have scales and also breathe air. Students inspect each animal picture, connect visible or known features with those definitions, and write the appropriate group beneath it. Including air breathing in both descriptions encourages attention to the distinguishing body covering instead of treating every listed trait as unique.
