This week in math, we will begin the week with a pre-test on algebraic equations. The data from this pre-test will be used to determine the extent to which students have mastered solving one-step, two-step and multi-step algebraic equations and plan instruction accordingly.
We will move on to our second mini unit, Unit 1b: Angle Relationships. In this unit, students will study similar triangles and the following angle relationships:
complementary angles
supplementary angles
adjacent angles
vertical angles
alternate interior angles
alternate exterior angles
corresponding angles
consecutive interior angles
Students will use facts about these angle relationships to solve algebraic equations and other types of problems. Vocabulary is extremely important in this mini unit. Students will need to be able to define and identify all of the angle relationships listed above as well as be familiar with the following:
parallel lines
perpendicular lines
intersecting lines
triangle angle-sum theorem
angle-angle criterion
