4.5B Input Output Tables

Front

What is an input-output table?

Back

An input-output table is a mathematical tool used to show how one set of numbers (inputs) relates to another set of numbers (outputs) through a specific rule or function.

Front

How do you find the rule in an input-output table?

Back

To find the rule, look for a consistent pattern or operation (like addition, subtraction, multiplication, or division) that relates the input values to the output values.

Front

If the input is 1 and the output is 2, what could be a possible rule?

Back

A possible rule could be 'add 1' since 1 + 1 = 2.

Front

If the input is 3 and the output is 12, what could be a possible rule?

Back

A possible rule could be 'multiply by 4' since 3 x 4 = 12.

Front

What does it mean to solve for an unknown in an input-output table?

Back

Solving for an unknown means to determine the input or output value when one of them is missing, using the established rule.

Front

If Mady counts 156 cookies and each bag has 12 cookies, how many bags does she have?

Back

To find the number of bags, divide the total cookies by the number of cookies per bag: 156 ÷ 12 = 13 bags.

Front

What is the equation for finding the number of packages if each package contains 8 pens?

Back

The equation is: Number of Pens ÷ 8 = Number of Packages.

Front

If you have 40 pens, how many packages do you have if each package contains 8 pens?

Back

Using the equation: 40 ÷ 8 = 5 packages.

Front

What is the importance of reading equations carefully?

Back

Reading equations carefully is important to ensure you understand the operations and relationships between numbers, which helps avoid mistakes.

Front

What operation would you use to find the total number of items if you know the number of packages and the number of items per package?

Back

You would use multiplication: Number of Packages x Number of Items per Package = Total Number of Items.
