# Mastery of the Function Unit

Lesson 13 of 13

## Objective: SWBAT complete multiple choice questions, short answers, and provide reasoning for identifying, evaluating, interpreting, and graphing functions.

*50 minutes*

The content that I expect students to master by the end of this unit is the following:

- Identify functions in multiple representations and provide reasoning
- Evaluating functions using equations and graphs
- Domain and Range of a function
- Graphing functions using a t-table

The type of questions that I will assess students is posted below:

- multiple choice
- short answer
- open response

In the following sections I will provide samples of test questions. I will not provide full tests because I used the state website Triand to give quick online assessments to my students as well as retakes throughout this Unit. I am giving shorter assessments this year due to the time needed to develop more in depth and rigorous curriculum for my students. Shorter assessments helps me focus on the content needs of my students. I either know to re-teach, re-test, or that the students have mastered that standard. I decided not to assess the students at this time on transformations of functions. I will test them at a later time within the unit for each function when we study each function more in depth.

One of the assessments that I gave students in this Unit was a quick online test through a state website www.triand.com for Arkansas that allows educators in Arkansas to use. I am providing a few Sample multiple choice questions . As you can see from the questions, they are quick assessments to check for student understanding of identifying functions, evaluating functions, and finding domain and range.

I also assessed students with an online test at www.triand.com using short answers. Here are some short answer Sample Questions. By providing a variety of different types of questions, students are more prepared for different formats. I like using short answer questions because students usually have to provide reasoning, but it is less time consuming than an open response question.

I also used Open Response questions from the Arkansas state website at www.triand.com. Here is a Sample of an Open Response Question on Functions. The Open Response is more time-consuming, but again it is important to provide students with questions that require them to provide reasoning in a written format. The more variety of representations that students, as well as repetition of problems, the better they will be prepared for the PARCC exam.
