Fourth-Grade Inquiry on Westward Expansion and Treaty Rights
A fourth-grade teacher has 27 students and three 45-minute social studies periods to teach westward expansion. The district requires inclusion of tribal history. The available materials are a textbook paragraph saying pioneers 'settled' free land and 'improved' it, a pioneer diary describing hardship and fear, and a treaty excerpt in which a tribal nation ceded land but retained hunting rights. Students ask, 'Was it fair?' One parent emails that the unit should be 'balanced' and not make children feel guilty. The teacher has no guest speaker but has a local tribal curriculum guide with approved excerpts. Most students can identify an author and date but rarely consider purpose or missing voices. The teacher wants students to use evidence and recognize multiple perspectives without turning the topic into a simple 'both sides' debate. The school's inquiry rubric expects a claim, at least two pieces of evidence, and source awareness.
1. Evaluate the three sources: what can each support, and what caution is needed?

Use all three, but not as equal 'sides.' The textbook can support broad sequence and vocabulary, but its language ('settled,' 'improved') frames expansion from one perspective; the teacher should mark that framing. The diary supports a pioneer's experience, including hardship and fear, but it is one person's account and says little about tribal nations. The treaty excerpt is a legal primary source that can support claims about land cession and retained rights, but an excerpt needs context: who negotiated, under what pressure, and what the tribe retained. The local tribal curriculum guide can supply the missing tribal voice and sovereignty context. Omitting it would make the sources unbalanced; using only the diary and textbook would let students miss the treaty. The caution is to avoid presenting the textbook as neutral and to give students a source log with author, purpose, audience, and missing voices.
2. Write a central question and two supporting questions for a three-day document-based inquiry, and explain how the questions build grade-level reasoning.

Central question: 'How did different people experience and justify changes to land in the West?' Supporting questions: 'Whose voices appear in each source, and whose are missing?' and 'What does the treaty say, and how does it compare with the textbook account?' Day 1: students read the textbook and diary, complete a source log, and identify claims. Day 2: small groups analyze the treaty excerpt and tribal guide, then add evidence to a class chart. Day 3: students write a short evidence-based response. The questions build reasoning because they move from comprehension to sourcing to comparison; they do not ask 'Was it good or bad?' in the abstract. The central question allows multiple evidence-based answers while requiring students to explain whose perspective they are using.
3. How will the teacher assess evidence-based reasoning and respond to the parent concern?
Read the worked answer
Assess with a three-part rubric: claim, evidence from at least two sources, and source awareness (author, purpose, missing voice). A proficient response might say westward expansion brought hardship and opportunity for pioneers but also broke treaty promises and changed tribal lives, using the diary and treaty. The parent concern should be answered by clarifying that the goal is historical reasoning, not guilt: students examine what people did and what institutions allowed, not whether they personally are responsible. The teacher can invite the parent to see the rubric and materials. Students should also reflect on how a single story can mislead; this addresses 'balance' without false equivalence between a diary and a treaty.
