Exploring Input/Output Tables for 3rd Graders

This video tutorial introduces input-output tables, explaining their real-world applications and layout. It covers how to apply consistent rules to transform inputs into outputs, identify patterns, and determine rules for changes. The tutorial also discusses inverse operations, emphasizing the importance of understanding both forward and backward transformations in input-output tables.

What is the purpose of an input and output table?

• To display a relationship between two numbers.

• To solve complex equations.

• To create graphs.

• To measure physical quantities.

Where are the inputs and outputs located in a standard input-output table?

• Inputs on the right, outputs on the left.

• Inputs on the left, outputs on the right.

• Inputs on the bottom, outputs on the top.

• Inputs and outputs are interchangeable.

If the input is 5 and the output is 7, what rule might be applied?

• Divide by 2

• Subtract 2

• Multiply by 2

• Add 2

What should remain consistent throughout the input-output table?

• The output numbers

• The input numbers

• The rule applied

• The table layout

How can you determine if the rule involves addition or multiplication?

• By checking if the output is larger or smaller than the input.

• By looking at the table layout.

• By guessing.

• By using a calculator.

If the input number is getting larger, which operation is likely being used?

• Subtraction

• Multiplication

• Division

• Addition

What is the inverse operation of addition?

• Addition

• Subtraction

• Division

• Multiplication

If the rule is 'input + 2 = output', what is the inverse rule?

• Input - 2 = output

• Output - 2 = input

• Output + 2 = input

• Input + 2 = output

Why is it important to understand the rule in both directions?

• To impress the teacher.

• To create more complex tables.

• To ensure the table is correct.

• To solve equations faster.

What happens if the rule is not consistent throughout the table?

• The outputs will remain the same.

• The inputs will change.

• The table will be incorrect.

• The table will still be correct.
