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 that show how one number (input) changes to another number (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 in how the input numbers change to become the output numbers.

Front

If the input is 1 and the output is 3, what could be a possible rule?

Back

A possible rule could be 'add 2' because 1 + 2 = 3.

Front

What is the output if the input is 5 and the rule is 'multiply by 4'?

Back

The output would be 20 because 5 x 4 = 20.

Front

In an input-output table, if the input is 10 and the output is 30, what is the rule?

Back

The rule is 'multiply by 3' because 10 x 3 = 30.

Front

What does it mean if an input-output table has a constant difference?

Back

A constant difference means that the output increases or decreases by the same amount each time the input increases.

Front

If Mady counts 156 cookies and each bag has 12 cookies, how many bags are there?

Back

There are 13 bags because 156 ÷ 12 = 13.

Front

What is the first number in a sequence?

Back

The first number in a sequence is the number that appears at the top or beginning of the list.

Front

If the input is 3 and the output is 12, what is the rule if the operation is 'add 9'?

Back

The rule is incorrect; the correct rule is 'multiply by 4' because 3 x 4 = 12.

Front

What is the output if the input is 7 and the rule is 'subtract 2'?

Back

The output would be 5 because 7 - 2 = 5.
