Unit of InstructionExponents and Scientific Notation
Standard(s) Taught

MAFS.8.NS.1.2  Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (like Pi squared).

MAFS.8.EE.1.1 Know and apply the properties of integer exponents to generate equivalent numerical expressions. (review)

MAFS.8.EE.1.3 Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities and to express how many times as much one is than the other.

MAFS.8.EE.1.4  Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used.  Used scientific notation and choose units of appropriate size for measurements of very large or very small quantities.

 

Learning Targets and Learning Criteria
  • Students will estimate approximations of square roots for imperfect squares.
  • Students will locate rational and irrational numbers on a number line.
