Mr. Sanchez explains how to recognize the difference between additive and multiplicative numerical patterns using graphs. The video includes two world problems: one involving shirt costs to demonstrate additive patterns and another involving food consumption to demonstrate multiplicative patterns. The video concludes with a summary of how to identify these patterns in graphs.

What is the main focus of the lesson introduced by Mr. Sanchez?

• Recognizing numerical patterns using graphs

• Understanding algebraic expressions

• Studying historical events

• Learning about geometric shapes

In the shirt cost problem, what is the initial cost of each shirt?

• $20

• $12

• $15

• $10

What is the shipping fee added to the cost of each shirt?

• $2.50

• $5.00

• $10.00

• $7.50

How is the relationship between the shirt cost and total cost represented?

• Y = X * 5

• Y = X + 5

• Y = X - 5

• Y = X / 5

What is the first step in creating an input/output table?

• Match the first dot on the graph

• Identify the Y values

• Determine the shipping fee

• Calculate the total cost

In the food consumption problem, what is the initial number of employees?

• 2

• 3

• 4

• 5

What is the correct equation for the food consumption problem?

• Y = X * 3

• Y = X / 2

• Y = X + 4

• Y = X - 3

How many units of food does each employee consume according to the pattern?

• 3 units

• 2 units

• 4 units

• 5 units

What is the purpose of applying the rule to the entire table?

• To find the shipping fee

• To determine the number of employees

• To calculate the total cost

• To verify the pattern

What is the final step in solving the food consumption problem?

• Apply the rule to the entire table

• Create a new graph

• Identify the number of employees

• Calculate the total food consumed
