Literal Equations (C) - Rearranging Formula WORKSHEET
Suitable for Grades: Algebra I, IM 1
CCSS: HSA.CED.A.4
CCSS Description: 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.
Literal Equations (C) - Rearranging Formula WORKSHEET DESCRIPTION
Literal Equations (C)- Rearranging Formula takes higher achieving students from rearranging formulae that take just one simple step to rearrange right through to more complex formulae that require as many as six steps and include inversing square roots and squaring. Some equations also contain parentheses. Students can consider what effect expanding the parentheses before rearranging has, and whether two different answers are equivalent.
All formulas are expressed in the form y =; the only variables used are x and y. Students are required to isolate x in each case, and x only appears once in each formula.
Learners can be encouraged to use substitution to check their rearrangement.
