🧭 Reasonableness Checks and Limits

The class studies sample pantry conclusions and practices deciding whether claims are supported by evidence, estimates, and the chosen model. Students then return to their own data to write a short conclusion frame that includes the claim, the math evidence, one limitation about the data or method, and one reasonableness check using estimation or inverse thinking. This just-in-time mini-lesson prepares students to defend conclusions before building the display.
