Grade 6 · Writing · Lesson 3

Use credible sources to support claims

A strong argument depends on reliable information. A source is credible when you can trust that the information it contains is accurate, honest, and up-to-date. Learning to evaluate sources before you use them is one of the most important skills in argumentative writing.
