Main Idea Practice

Student reading and identifying main ideas

📚 Part 1: Reading Comprehension

Read the following passage carefully:

Monarch butterflies are famous for their incredible journey across North America. Every fall, millions of these orange and black butterflies travel up to 3,000 miles from Canada and the northern United States to central Mexico. What makes this migration even more amazing is that the butterflies making the trip south have never been there before. They use the sun's position, air currents, and Earth's magnetic field to navigate. The journey can take up to two months to complete. When spring arrives, the monarchs begin their return trip north, but it takes three to four generations to complete the full journey back.
