U.S. history · How freedom grew over time · Grades 3–5
Premise: The Liberty Bell is a symbol of freedom — but "liberty for everyone" grew step by step over many years. Students read clues about 1776, the end of slavery, and expanding voting rights, and claim only what the clues actually prove (including that not everyone was free in 1776).
Students open the clue board and solve four locks (a word lock, an evidence lock, a year lock, and an evidence-sort lock where they must pick every true step and no false ones). Each lock reveals a short reasoning explanation when solved. The answer key is not shown on this page.

Skills & standards alignment
Content is aligned to these strands; the activity is a supporting resource, not a verbatim standard statement:
Texas TEKS · Social Studies (Gr 5): key events and individuals in the expansion of rights and freedoms in United States history.
Texas TEKS · Social Studies (Gr 3–4): how individuals and events have changed communities and the nation over time.
Common Core ELA · RI.3–5.1 & RI.3–5.3: use text details to support inferences and describe events and ideas across time.
Reasoning habit: distinguishing supported conclusions from unsupported guesses ("prove it from the clue").
💡 Teacher tip: The evidence-sort lock is the key teaching moment: students must reject "everyone was already equal in 1776" even though it sounds patriotic, because the clues show otherwise. Honest history means following the evidence.
