4. Data and Probability
Approximate dates: December- January
LT4.1: I can use the mean, median and range to draw conclusions about data and make predictions.
LT4.2: I can display and interpret data in a variety of ways. (line plots, circle graphs, stem and leaf, histograms)
LT4.3: I can calculate probabilities and reason about probabilities using proportions.
5. Equations and Solving
Approximate dates: January
LT5.1: I can evaluate algebraic expressions, including expressions containing radicals and absolute values, and justify the algebraic properties.

6. Linear Relationships
LT6.1: I can represent linear functions with tables, equations, graphs, context and language including identifying the slope and y-intercept.
LT6.2: I can represent and solve real-world and mathematical situations using linear equations and inequalities.
LT6.3: I can recognize that a function is linear if it is written in the form f(x) = mx + b and interpret the meaning of the y-intercepts and slope.
7. Systems of Equations
April - May
LT7.1: I can solve problems involving parallel and perpendicular lines in a coordinate graph.
LT7.2: I can solve a system of equations by using a graph, substitution, and elimination, and determine if the system has 0, 1, or infinite solutions.
LT7.3: I can model a context using a system of linear equations.
8. Pythagorean Theorem
LT8.1: I can classify real numbers as rational or irrational, and approximate the value of irrational numbers and locate them on the number line.
