About this worksheet
Sentences from a source, like "Sloths move so slowly that tiny plants called algae can grow on their fur," to underline key words and write a short note. Fewer, Standard or More give 4, 5 or 6. The answer key shows key words and a sample note.
What kids practice
Research means finding facts from more than one source and taking notes to use in your own writing. Good notes are short: key words and phrases in your own words, not copied sentences. Fourth graders sort their notes into subtopics, which become the paragraphs of an informative essay, and keep a list of the sources they used.
Watch for
- Copying whole sentences from a source instead of writing key words.
- Writing down every fact, even ones that don't answer the research question.
- Forgetting to write down where a fact came from.
- Using only one source.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full research notes guide for 4th grade.
