Common Mistakes to Watch For

• Choosing a small detail (like 'dogs wag their tails') as the main idea instead of the bigger point (like 'dogs are friendly pets'). First graders often grab the first fact they remember rather than thinking about the whole passage.
• Confusing the topic with the main idea. A first grader might say the passage is about 'rain,' but the main idea is a full sentence like 'rain is important for plants and people.'
• Picking a 'detail' that wasn't actually in the passage but sounds true in real life. Kids this age sometimes answer from background knowledge instead of looking back at the text.
