MA19.7A.16

Mathematics (2019) Grade(s): 7 - Grade 7 Accelerated

Students know:

That scientific notation is formed using base ten system and is the reason a 10 is used as the base number.
Raising or lowering an exponent is has an effect on the place value of the decimal expansion.
That scientific notation is formed using a base ten system.
how to apply laws for multiplying and dividing exponents

Students are able to:

Write numbers in standard notation in scientific notation.
Convert numbers from scientific notation back to standard form.
Use information given in scientific notation to estimate very large or small quantities given in real-world contexts.
Perform multiplication and division with numbers expressed in scientific notation to solve real-world problems, including problems where both scientific and decimal notation are used.
Choose between appropriate units of measure when determining solutions or estimating

Students understand that:

The movement of decimals in converting between scientific and standard notation is a function of an exponent.
Every decimal place represents a power of ten (this is a connection many students have not made yet when thinking about place value).
Scientific notation has real-world applications for very large and very small quantities found in many disciplines.
performing scientific notation operations are another application of integer exponent operations.
