Unit Abstract

Eight Grade

  • Classify and determine the measures of angles created when parallel lines are cut by a transversal.
  • Demonstrate that the sum of the interior angle measures of a triangle is 180° and apply this fact to find the unknown measures of angles and the sum of the angles of polygons.
  • Use similar triangles to solve problems that include height and distance.

Lesson Plan Sequence
The following lesson plan sequence is obtained from Big Ideas Learning (2015). Each lesson is aligned with a learning objective to inform the teachers on what students should be able to do at the end of the lesson. The student objective informs the students of their learning goals for the day and it should be reviewed before, during and at the end of the lesson. Each lesson includes a mathematics task that should be implemented to meet the learning objectives. Teachers can select from the practice opportunities to reinforce the learning goals of the day.

Language Support
The use of sentence stems as a language support are beneficial to all students, including English Language Learners. The use of sentence stems encourages the learning of mathematics in a language rich environment which has an impact on other learning as well. The sentence stems are a beginning place for supporting students' use of academic language and encourage discussion and writing as students learn content.
