2.8 Literal Equations & Dimensional Analysis

Standard(s):

  • A.REI.B.3:  Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
  • A.CED.A.4:   Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations. For example, rearrange Ohm's law V = IR to highlight resistance R.


Essential Questions:

  • Can equations that appear to be different be equivalent?

Learning Targets:

  • I can identify the parts of a literal equation. (Comprehend)
  • I can identify the operations within a literal equation. (Comprehend)
  • I can identify the inverse operation needed to solve a literal equation. (Comprehend)
