# Summary

This lesson will incorporate the use of the Keynote app on the iPad. Students will need to demonstrate their understanding of multiple representations of an arithmetic sequence. Students will spend a class period creating the presentation.

# Background for Teachers

To teach this lesson, teachers need an understanding of the Keynote App. They will also need an understanding of arithmetic sequences.

Required: Ipad with Keynote App

# Goals and Outcomes

Learning Intentions:

Students will be able to demonstrate their understanding of Arithmetic sequences by creating a presentation with a group.

Students will create a recursive formula, explicit formula, and graph a function given an arithmetic sequence.

# Planning Instruction

Prior to this lesson, students will have an understanding of arithmetic sequences and their multiple representations.

Standard F.IF.3 Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers. Emphasize arithmetic and geometric sequences as examples of linear and exponential functions. For example, the Fibonacci sequence is defined recursively by f(0) = f(1) = 1, f(n+1) = f(n) + f(n-1) for n ≥ 1.

# Instruction:

1) (15 min) Warm up problem. Teacher will present an arithmetic sequence. Students will write a recursive and explicit equation as well as graph the function. Teacher will go over the problem.

2) (15 min) Keynote Project. Teacher will introduce the expectations for the project. Teacher will show the rubric as well as example.

3) (30 min) Project Work Time. Teacher will put students in groups and assign each group a sequences. Students will create a Keynote Presentation to show the multiple representations of their unique sequence. Teacher will circulate for students needing extra help.

4) (30 min) Present. Each group will present their Keynote to the class.

# Assessments:

Teacher will watch each presentation and grade students based on the rubric.
