MAthematics 9 Linear Equations and inequalities
Specific Curriculum Outcomes
PR03 Students will be expected to model and solve problems, where a, b, c, d, e, and f are rational numbers, using linear equations of the form.
PR04 Students will be expected to explain and illustrate strategies to solve single variable linear inequalities with rational coefficients within a problemsolving context.

 ax = b
 x/a = c, a not equal to 0
 ax + b = c
 x/a + b = c, a not equal to 0
 ax = b + cx
 a(x + b) = c
 ax + b = cx + d
 a(bx + c) = d(ex + f)
 a/x = b, x not equal to 0

PR03 activities
 Solving MultiStep Equations Visually  How Many Sour Patch Kids Are In A Bag? a video from Kyle Pearce  Introducing solving linear equations can be challenging when students have a difficult time visualizing the algebra we are using. Start with a visual of candy on a scale, then slowly introduce variables once students get the hang of it! Here, the equation we are looking at is 3x + 6 = 4x + 3.
PR04 Activities
 Inequalities on the Number Line Desmos Activity  In this activity, students explore linear inequalities and make connections among multiple representations (including algebraic expressions, verbal statements, number line graphs, and solution sets).

 Inequalities Point Collector Desmos Activity  In this activity, students apply (and deepen) their knowledge of onevariable inequalities to "collect" as many points on the number line as they can. The activity focuses on simple and compound inequalities. More advanced inequalities are welcome, but not required.
 Inequalities Matching Card Sort from Sarah Carter  Students match cards with algebraic inequalities to the pictures of their graph on a number line.
 Solving Inequalities Card Sort  Students match cards of inequalities, solution and graph.
