The video tutorial introduces the concept of comparison bars to solve story problems. It uses the example of Tessa and Sam's pens to explain how to determine the difference in quantity. The tutorial covers four examples, each illustrating different aspects of comparison bars, such as finding missing numbers and calculating totals. The lesson emphasizes understanding how questions are worded differently and how that affects the solution. The tutorial concludes with a summary of the lesson's objectives and encourages parents to assist with homework.

What is the purpose of using comparison bars in solving story problems?

• To compare the size of different objects

• To confuse the students

• To visually represent numerical relationships

• To make the story more interesting

In the example, how many pens does Tessa have?

• 6 pens

• 9 pens

• 12 pens

• 15 pens

Why is Tessa's bar longer than Sam's in the comparison bar?

• Because Sam has more pens

• Because Tessa is taller

• Because Tessa has more pens

• Because Tessa's pens are bigger

How many more pens does Tessa have than Sam?

• 12 pens

• 9 pens

• 6 pens

• 3 pens

What is the difference in the number of pens between Sam and Tessa?

• 6 pens

• 9 pens

• 3 pens

• 15 pens

How many fewer pens does Sam have compared to Tessa?

• 6 fewer pens

• 9 fewer pens

• 15 fewer pens

• 3 fewer pens

What method is used to find the missing number in the example?

• Math Mountain

• Number Line

• Bar Graph

• Pie Chart

If Sam has 9 pens and Tessa has 6 more, how many pens does Tessa have?

• 12 pens

• 9 pens

• 6 pens

• 15 pens

What is the missing number when Sam has 6 fewer pens than Tessa?

• 15

• 6

• 12

• 9

How can students solve for the missing number using their fingers?

• By counting up from 6

• By counting down from 15

• By counting up from 9

• By counting down from 12
