Solving Basic Addition and Subtraction Problems

The video tutorial introduces a worksheet called 'Guess the Number' and guides students through solving equations using function machines. It explains the concept of input and output columns, and how to determine the correct rule for each function machine. The tutorial also covers the associative property, demonstrating how it helps in solving equations. Students learn to apply addition and subtraction to find missing numbers, with step-by-step examples provided. The video concludes with solving a final problem and a recap of the lesson.

What is the purpose of the input-output columns in the function machine?

• To identify the largest number

• To determine the rule for the equation

• To check if the numbers are even

• To find the missing number

In the first equation, why do we choose subtraction instead of addition?

• Because 8 is larger than 7

• Because 7 is smaller than 8

• Because 8 is an even number

• Because 7 is an odd number

What is the associative property used for in the video?

• To identify even numbers

• To convert subtraction to addition

• To check if the rule is correct

• To find the largest number

How do we solve the equation 2 + something = 12?

• By multiplying 2 by 6

• By adding 10 to 2

• By subtracting 2 from 12

• By dividing 12 by 2

What rule is used to solve the equation 8 + something = 18?

• Multiply by 2

• Add 10

• Subtract 8

• Divide by 2

In the final problem, what operation is used to find the missing number?

• Subtraction

• Division

• Addition

• Multiplication

What is the rule for the equation 12 - something = 8?

• Add 4

• Add 3

• Subtract 4

• Subtract 3

How do we verify the rule in the final problem?

• By checking with another example

• By using a calculator

• By guessing

• By using a different rule

What is the result of 14 - 4?

• 12

• 6

• 8

• 10

What is the final step in solving the last problem?

• Using the associative property

• Guessing the answer

• Drawing it out

• Using a calculator
