Functions
A function is like a machine that has an input and an output. Challenge scholars to look at the eight given points and determine the two functions that would fit four of the points each — one is linear and the other non-linear. The...

Divide and Conquer: Division Rules
For this division rules worksheet, learners name the division rules used in a set of tables, then fill in missing input and output numbers to complete, 4 tables total.
Curated OER
Mixed Tables
Who knows how to operate these multiplication machines? Young mathematicians examine five machines, each with a specific function (i.e. x3) to transform the input numbers to output numbers. They send five numbers through each machine,...

Doubling and Halving
In this double the numbers and half the numbers worksheet, students problem solve by doubling, complete an input-output table by halving, and play a dice game and doubling the numbers. Students solve 28 problems.

Relations and Functions
Learners differentiate between a relation and a function. In this algebra lesson, students identify a pair of coordinates as being a relation or a function. They analyze graphs for function as they solve word problems.

Functions Tables Activity
In this functions activity, learners complete a set of 4 function tables using a given rule, then answer a set of 3 additional related questions. Answers are included on page 2.

Viral Marketing
Math's gone viral—in the form of an exponential function! The activity uses an exponential function to model the growth of a marketing strategy. Learners create a table of values to observe the pattern in the numbers and then model the...

Exploring Function Tables
For this exploring function tables worksheet, 3rd graders take the input number, follow the rule at the top of the table and write the output number for six tables.
Curated OER
Function Tables
In this function tables practice worksheet, students use their problem solving skills to solve 12 problems that require them to determine the rule followed in each of the function tables.
Curated OER
Function Tables
In this function tables worksheet, students analyze 6 different function tables to determine the rule that applies to each table. The data in the table involves 2 variables and the rule is either addition, subtraction, multiplication...

Sorting Functions
Graph A goes with equation C, but table B. The short assessment task requires class members to match graphs with their corresponding tables, equations, and verbalized rules. Pupils then provide explanations on the process they used to...

Point-Slope Application Problems
Create a linear equation for a problem when the intercept information is not given. The two-day lesson introduces the class to the point-slope form, which can be used for problems when the initial conditions are not provided. Pupils...

Quadratic (2009)
Functions require an input in order to get an output, which explains why the answer always has at least two parts. After only three multi-part questions, the teacher can analyze pupils' strengths and weaknesses when it comes to...

How are we Related?
Students differentiate functions based on their domain and range. For this algebra lesson, students define function, domain, range and relation. They analyze graphs and coordinate pairs for input and output values making up a function.

Functions and Their Graphs
Use a worksheet to go over the basic concepts of relations and functions. Included are clear definitions and examples of relations, domain and range, and functions and the vertical line test. However, the problems are pretty...

Invertible or Not?
What determines whether a function has an inverse? Learners investigate that criteria when they examine values in a partially completed input-output table for two different functions. The task is to complete the table so that one of the...

Smarter Balanced Sample Items: 8th Grade Math – Target E
One of several presentations of eighth grade sample items looks at the basics of functions. Smarter Balanced sample items for Target E highlights the way function content shows up on the assessments. The presentation contains eight items...
Shodor Education Foundation
Two Variable Function Pump
Use a function to operate on two variables. Pupils look at operating with complex numbers as a function of two variables. The interactive squares the input and adds a constant to it. Learners visualize the resulting output and its...

Functions and Their Graphs.
Students solve equations and label it as a function or not. In this algebra lesson, students make a table of values and graph their equation. They identify the domain and range of each graph.

Multiple Representations of Equations
class members first work through finding the equation, table of values, graph, and key features of a linear function expressed verbally. Individuals then work through several more problems given different representations.
