Premise: Students learn the structure of an evidence-based proposal by designing a school observance: identifying a clear claim, real evidence, significance, and a response to objections — and ordering those parts.
Students solve four locks (an evidence-sort, an evidence lock, a word lock, and an order lock). Each lock reveals a short reasoning explanation when solved. The answer key is not shown on this page.
Student activity: grade912/observancedesign-student.html · ~10–15 minutes · works on tablets, laptops, and interactive whiteboards.
Skills & standards alignment
Content is aligned to these strands; the activity is a supporting resource, not a verbatim standard statement:
Texas TEKS · U.S. History / Government (skills): create written and oral arguments using supporting evidence and addressing counterarguments.
Common Core Writing · W.11–12.1: write arguments with a clear claim, evidence, and attention to counterclaims.
Common Core Literacy · RH.11–12.8: evaluate an argument’s premises, claims, and evidence.
Reasoning habit: structuring a claim, evidence, significance, and response to objection.
💡 Teacher tip: Have students draft one real proposal after the breakout — the order lock (claim → evidence → significance → response) doubles as their outline.
📋 Texas framing (TEC §28.0022): This activity presents slavery and racial injustice as failures to live up to the nation’s founding principles of liberty and equality — the gap Frederick Douglass named — consistent with Texas law. A teacher who chooses to discuss related controversial topics should explore them objectively and free from political bias. Content is aligned to the 2022 Texas Social Studies TEKS.
