Question Exploration: How Much Does 1+1= In Significant Digits?

How much does 1+1? It can depend on significant digits. This concept comparison contrasts accuracy and precision in measurement, and the question exploration explains how to use all the significant figure rules to make measurements, as well as how to round to the right number of sig figs when using scientific notation.

Question Exploration Routine is an instructional methods that teachers can use to help a diverse student population understand a body of content information by carefully answering a critical question to arrive at a main idea answer. The Concept Comparison Routine is used help compare and contrast key concepts. Specifically, students use like and unlike characteristics and categories shared and not shared by two or more concepts to better understand the overall concept. Students taught using Content Enhancement routines earned higher total test scores than did students taught using the lecture-discussion method.

This product includes both the completed question exploration guide and concept comparison, and the student guide blanked except for vocabulary, scaffolding questions, and graphics already filled in. It includes warm ups, worksheets, and recommended videos for review, and it's is in Microsoft Word .doc form so that Ts can customize the discussion to fit the needs of their Ss.

This Question Exploration has been classroom tested to help students with the following Florida Next Generation Sunshine State Standards in Science:
