About this worksheet

Cause and effect help readers explain how events connect. A cause tells why something happened, and an effect tells what happened because of it. Third graders may reverse the two, especially when both ideas appear in the same sentence. They may also choose an event that is in the passage but is not connected to the target event. This worksheet uses short passages with clear relationships, then asks students to identify causes, effects, and matching pairs. Encourage your child to use the words because and so as a test. If the sentence makes sense with because, the cause is probably in the right place. Students should explain the connection, not only repeat a sentence from the passage. That explanation proves they understand the relationship.

What your child will learn

  • Identify causes in a passage
  • Identify effects in a passage
  • Match connected events
  • Avoid reversing cause and effect
