Seeds on the Move
Grade 3 · Nonfiction · cause and effect
Read the passage carefully. You may underline parts that help you answer.
Plants cannot walk, but their seeds can travel far away. This helps new plants grow without crowding the parent plant. Seeds move in several different ways, depending on their shape and size.
Some seeds, like dandelion seeds, have fluffy parts that catch the wind and float far away. Other seeds, like burrs, have tiny hooks that stick to animal fur. The animal carries the seed to a new spot before it falls off.
Some seeds even travel by water. Coconuts can float across the ocean and land on a new beach, where they may grow into a tree. All of these methods help plants spread their seeds to new places where they can grow.
Answer the questions. Use details from the passage.

Open worksheetWhat 3rd grade reading covers
Third graders make inferences based on clues in the text, identify cause-and-effect relationships, and distinguish main ideas from supporting details across longer passages.
Nonfiction passages start including text features like headings and simple diagrams that support comprehension.
How much practice is enough
Two to three passages a week, with a short discussion after each one, builds inference and main-idea skills steadily without feeling like a chore.
How to teach inference, cause and effect, and main idea in longer passages
- 1
Ask what the character is feeling
Since text may not state feelings directly, ask your child to infer emotions from characters' actions and words.
- 2
Identify cause and effect
Point out one event in the passage and ask what caused it or what happened as a result.
- 3
Separate main idea from details
Have your child list two or three supporting details that back up the passage's main idea.
- 4
Use text features in nonfiction
Point out headings, bold words, or captions and ask how they help explain the passage's topic.
Tips for parents and teachers
- Encourage your child to justify inference answers with a specific clue from the passage.
- Alternate story passages with short nonfiction articles on science or history topics.
- Discuss unfamiliar vocabulary using context clues before checking a dictionary.
- These free printable PDFs with answer keys support homeschool reading practice and classroom review.
