Learning Activity

What's the Function?

Subject Area

Mathematics

Grade(s)

Overview

Answer Garden is an online brainstorming tool that easily exports into other digital tools, such as Wordle or Tagxedo. It will also create a QR code which will facilitate easy access in a BYOD or 1:1 environment.

Content Standards

Mathematics (2019) Grade(s): 8

MA19.8.13
Determine whether a relation is a function, defining a function as a rule that assigns to each input (independent value) exactly one output (dependent value), and given a graph, table, mapping, or set of ordered pairs.

Unpacked Content

Vocabulary

Evaluate
Input
Output
Function

Knowledge

Students know:

how to apply order of operations.
That every input will produce one output for a given function.

Skills

Students are able to:

analyze a rule or an equation
Substitute given values for the input to produce a desired output.

Understanding

Students should understand that:

An output for any function is controlled by the input for that function. This is important to help reinforce/establish the concept of inputs being the independent variable and outputs representing the dependent variable.

Interdisciplinary Connections

Phase

During/Explore/Explain

After/Explain/Elaborate

Learning Objectives

The students will analyze functions in various forms.

Activity Details

Through the course of the lesson, or at the end, the teacher will display a function (graph, table, etc.) and ask the students to determine the expression that will accurately describe it.

Students may work individually or with a partner to determine the solution and then submit it to the Answer Garden. Multiple students may use the same device.

The teacher can create a QR code to allow students to access the garden more quickly if desired.

The teacher may mouse over each answer to see how many submitted that specific answer or simply export to Wordle where the most popular response will be the largest.

Assessment Strategies

The teacher will immediately recognize whether or not students understand by viewing the results. If there is any question, the teacher may ask a student to orally discuss their solution.

Acceleration and Intervention

Background and Preparation

Background / Preparation

The teacher will need to create an Answer Garden (and QR code, if desired.)

If a QR code is to be used, the teacher must ensure that student devices have a QR Reader installed.

The function may be displayed with a projector, on a whiteboard or could simply be a problem in the text to which students are directed.
