Line and circle, proportionality, line in a coordinate system, Thales’ theorem, systems of equations, similar triangles, real numbers, translation vectors, algebraic expressions, trigonometric relations, analytic geometry, and statistical surveys.
In each topic, students go through the following steps to master the learning objectives: introducing new information by building on previous knowledge through the parts “To think,” “Recall,” “Activity,” and “I conclude”; applying directly in the “Application” section; wrapping up the rules in the “Rules for you” section; and then practicing through exercises escalating in their levels in the “Exercises and Problems” sections.
