Reading Informational Text: Main Idea, Structure, and Evidence
What the domain tests
Reading Informational Text on the Georgia Milestones Grade 5 ELA assessment covers articles, biographies, historical texts, and technical passages. The Georgia Standards of Excellence (ELAGSE5RI1–RI9) ask you to quote accurately, infer, determine main idea and summarize, explain relationships and interactions, compare text structures, analyze multiple accounts of the same event, explain how reasons support points, and integrate information from several texts.
Core rules
- Main idea is the whole-text point. It is what the passage is mostly about, not the first detail you see. Supporting details explain, prove, or illustrate it. A strong summary states the main idea and the most important details without opinions.
- Quote and explain. Use exact words for evidence, then explain how those words support your answer. A quotation alone is not an explanation.
- Name the relationship. Look for cause-and-effect, compare-and-contrast, sequence, and problem-and-solution links. Signal words such as because, however, before, and as a result show how ideas connect.
- Text structure is a tool. Chronological structure organizes events by time; comparison organizes similarities and differences; cause-and-effect explains why something happened. Ask how the structure helps the author’s purpose.
- Multiple accounts need comparison. Two texts about the same event may differ in focus, facts included, or the author’s feelings. Identify firsthand and secondhand accounts and compare what each emphasizes.
- Reasons need evidence. Find the author’s point, then check which reasons and facts actually support it. An opinion repeated is not evidence.
- Integrate across texts. When a question names two passages, your answer must combine information from both, not summarize only one.
Worked example
Passage sentence: “The town added protected bike lanes on Main Street. After the change, the number of bicycle crashes fell by half, and more students began riding to school.”
Question: How does the evidence support the idea that the bike lanes improved safety? Reasoning: The claim is improved safety. The first detail-crashes fell by half-directly measures fewer accidents. The second detail-more students riding-shows increased use but does not by itself prove safety. A strong answer cites the crash decrease and explains that fewer crashes is evidence of safer riding.
Traps that cost marks
Picking a supporting detail as the main idea; treating the author’s opinion as a fact; ignoring the second passage; mislabeling a sequence as cause-and-effect; quoting evidence without explaining it; confusing a firsthand account with a secondhand one.
