Understanding Input-Output Rules

The video tutorial covers the 'What's My Rule' lesson from Everyday Math. It explains how to apply mathematical rules to numbers, such as subtracting seven or adding nine, to determine the output. The tutorial also guides students on how to discover rules by analyzing number patterns and encourages them to create their own rules. The lesson emphasizes understanding the relationship between input and output numbers and practicing these concepts through in-and-out boxes.

What is the main focus of the 'What's My Rule' lesson?

• Learning multiplication tables

• Understanding in and out boxes

• Practicing division problems

• Exploring geometric shapes

If the rule is 'subtract seven', what is the output when the input is 14?

• 28

In the 'add nine' rule, what is the output when the input is 7?

• 7

• 16

• 18

• 9

How do you find the input if the output is 18 using the 'add nine' rule?

• Subtract 9 from 18

• Divide 18 by 9

• Multiply 18 by 9

• Add 9 to 18

What is the rule if the input is 70 and the output is 100?

• Add 30
