Inductive and Deductive resoning



  • Students may have trouble with reasoning inductively (using specific facts to lead to a idea).
  • Students may have trouble with reasoning deductively (using general facts to lead to specific facts or idea).
  • Students need help learning new ways to think about ideas and facts.


  • Show how to use graphic organizers to help them reason inductively.
  • Show the thought process of reasoning deductively.
  • Educate students on how to use inductive and deductive reasoning to understand content area information and ideas. 

Content-area Objectives

Learning Strategies

Mathematics: use

specific math facts or information to lead to a general rule or idea

Inductive reasoning graphic organizer

Science: use a general idea in science to lead to specific information and a conclusion

Deductive reasoning graphic organizer






Reason inductively

using specific facts to lead to a idea

Every cat you have seen has 4 legs. Inductive reasoning would tell you every cat has 4 legs.

Reason deductively

using general facts to lead to specific facts or idea
