END OF UNIT COMPETENCIES WITH LANGUAGE EXPECTATIONS

By the end of Unit 1, students will be able to: ● write explicit and recursive equations for a given sequence both procedurally and in context ● fnd specifc terms of an arithmetic or geometric sequence ● model an arithmetic or geometric sequence using various representations ● compare and contrast sequences ● explain the differences between an arithmetic and a geometric sequence by using correct math vocabulary such as: ○ arithmetic, geometric, sequence, constant difference (common), explicit, recursive, constant ratio (common), arithmetic mean SCAFFOLDING IN ACTION

● Lesson 1.1: JumpStart - provide sentence frames for discussion, Launch manipulatives, graph paper, colored pencils to explore the pattern, Explore - start with a simpler problem (3x3, 4x4), Discuss - Think-Pair-Share ● Lesson 1.2: Launch - manipulatives, colored pencils to group and count the dot, Discuss - graphic organizer for students to record their thinking about recursive vs explicit, multiple representations ● Lesson 1.3: Jump Start - Which One Doesn’t Belong? Launch - Notice and Wonder, manipulatives, colored pencils to group and count dots, Explore - graphic organizer for students to record their thinking ● Lesson 1.4: Explore - graphic organizer for students to record their thinking recursive & explicit models, provide sentence frames for discussion, Discuss - Think-Pair-Share, ● Lesson 1.5: Launch - 3 Reads/Word-Phrase-Sentence, Explore - graphing calculator ensure correct calculations, view table, Discuss - graphic organizer for students to record their thinking ● Lesson 1.6: Launch - read aloud, provide contextual visuals, Explore - graphic organizer for recursive thinking, Discuss - graphic organizer to record their comparative fndings ● Lesson 1.7: Explore - Think-Pair-Share, Explore - chunk the task and divide the work among group members ● Lesson 1.8: Explore - chunk the task, ● Lesson 1.9: Jump Start - Which One Doesn’t Belong? Explore - chunk the task, provide calculator for power function or nth root function, Discuss - Think-Pair-Share ● Lesson 1.10: Launch - refer back to “Take Aways”, Explore - chunk the task by providing choice
