							Methods for solving linear equations of the form
a)    Traditional approach
                                                Summative Assessment
                 Methods
                                                    Example(s)
i)    use of number facts (“solve
      mentally”)

ii)   generate and evaluate (“guess
      and check” or “trial and error
      substitution”)
iii) undoing (or working
     backwards)

iv) cover-up



v)    transposing (change side -
      change sign)

vi) equivalent equations
    (performing the same
    operation on both sides)


b) Functions approach (solve: 3x – 4 = x + 6)
                  methods                  Summative Assessment example(s)
i)    table using graphing calculator
      (similar to guess and check)




ii) graphing
