The Common Core state standard used through this learning segment is 8.EE.A.4: Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. Use scientific notation and choose units of appropriate size for measurements of very large or very small quantities (e.g., use millimeters per year for seafloor spreading). Interpret scientific notation that has been generated by technology. For this learning segment, we will only be covering the first part of the standard where students will be performing operations in scientific notation. This standard addresses conceptual understanding because students must understand the meaning of scientific notation in order to perform operations …show more content…
It also addresses procedural fluency in that students, with conceptual understanding, will “perform operations,” building on the arithmetic skills they already have with their procedural fluency of exponent laws. Students will use problem-solving skills when they must decipher context to find relevant information in order to perform operations in scientific notation. The lesson 1 learning objective, “given a very large or small number, scholars will be able to write an expression equal to it using a power of 10 and identify whether or not a number is written in scientific notation,” will address conceptual understanding and mathematical reasoning as students make a connection between powers of 10 and their prior knowledge of place value, understanding that the power of 10 has meaning. Students must then use mathematical reasoning to judge how large or small a power of 10 is. In this comparison, they will show conceptual understanding on the meaning of exponents as repeated multiplication. Procedural fluency will be addressed in students being able to recognize that a number is correctly written in scientific notation and being able to
