QUESTION 1
What does it mean to synthesize sources?
To weave together evidence from multiple sources into one original argument — showing how they relate, rather than summarizing each separately.
QUESTION 2
Why must you cite your sources?
To give credit, avoid plagiarism, and build your own credibility.
QUESTION 3
In a synthesis essay, whose argument should drive the writing?
Your own — the sources support your thesis; they don’t replace your analysis and voice.

Going deeper? Add a counterargument.

Have students find a source that challenges their thesis, then address and rebut it in their synthesis — strengthening the whole argument. A printable synthesis sheet is in the ELA library.
