Exploring Input and Output Tables in Math

What is the main task for today’s lesson?

• Completing 'What's the Rule' problems

• Learning about different types of robots

• Building a new robot

• Programming a computer

What does 'input' refer to in the context of this lesson?

• The error in the calculation

• The rule applied by the robot

• The number that goes into the machine

• The final result

If the input is 5 and the robot's rule is 'plus two', what is the output?

• 10

• 3

• 5

• 7

Which table does the 'plus two' rule work for?

• The table where 6 goes in and 3 comes out

• The table where 5 goes in and 7 comes out

• The table where 4 goes in and 1 comes out

• The table where 5 goes in and 1 comes out

What is the rule of the second robot?

• Divide by two

• Subtract four

• Multiply by two

• Add four

Does the 'subtract four' rule work for the table where the input is 6 and the output is 3?

• Sometimes

• Only if the input is even

• No

• Yes

If the input is 5 and the rule is 'subtract four', what is the output?

• 4

• 9

• 0

• 1

What is the output if the input is 4 and the rule is 'subtract four'?

• 8

• 4

• 2

• 0

What should you do to ensure the rule works correctly?

• Change the rule frequently

• Test only one input

• Test multiple inputs

• Ignore the outputs

What is the purpose of the rule in the context of this lesson?

• To ignore the output

• To change the input

• To determine the output

• To determine the input
