4.5B Input Output Tables

Front

What is an input-output table?

Back

An input-output table is a way to organize pairs of numbers where each input has a corresponding output based on a specific rule.

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 to the output.

Front

If the input is 2 and the output is 10, what could be a possible rule?

Back

A possible rule could be 'multiply the input by 5' because 2 x 5 = 10.

Front

What is the output if the input is 4 and the rule is 'add 3'?

Back

The output would be 7 because 4 + 3 = 7.

Front

If the rule is 'multiply by 2', what is the output for an input of 6?

Back

The output would be 12 because 6 x 2 = 12.

Front

What does it mean if an input-output table has a consistent pattern?

Back

It means that the same operation is applied to each input to get the corresponding output.

Front

How can you use an input-output table to solve for an unknown?

Back

You can use the rule to determine the output for a known input or find the input that gives a specific output.

Front

If Mady counts 156 cookies and the rule is 'divide by 12', how many bags of cookies does she have?

Back

Mady has 13 bags of cookies because 156 ÷ 12 = 13.

Front

What is the first step to solve an input-output problem?

Back

The first step is to identify the rule that connects the input to the output.

Front

If the input is 5 and the output is 25, what is the rule?

Back

The rule is 'multiply by 5' because 5 x 5 = 25.
