Two-Step Problem Solving Strategies

The video tutorial teaches how to solve one-step and two-step questions using bar graphs. It begins with an introduction to bar graphs and their use in problem-solving. A simple one-step question is demonstrated, followed by an explanation of two-step questions and common mistakes. The tutorial then applies these concepts to solve a complex two-step question using a bar graph, emphasizing the importance of completing all steps. The lesson concludes with a summary of the key points covered.

What is the purpose of a modeled drawing in solving problems?

• To eliminate the need for calculations

• To provide an exact numerical answer

• To make the problem more complex

• To create a visual representation of a problem

In the marble example, how many more marbles does Mark have than Kate?

• Five

• Three

• Two

• Four

What is a common mistake when solving two-step questions?

• Using a calculator

• Completing only the first step

• Skipping the first step

• Ignoring the question

• Twenty-four

• Nineteen

• Sixteen

• Seven

What is the total number of students on the Maple Street and Oak Lane buses?

• Thirty-six

• Forty

• Forty-four

• Thirty

What is the first step in solving the two-step question about the buses?

• Add the students from Maple Street and Oak Lane

• Subtract the students from Alder Avenue and Pine Place

• Multiply the number of students on each bus

• Divide the total number of students by two

What is the second step in solving the two-step question about the buses?

• Compare the totals from the first step

• Add the students from Alder Avenue and Pine Place

• Subtract the total from the first step

• Multiply the totals from the first step

How many more students ride on the Maple Street and Oak Lane buses compared to the Alder Avenue and Pine Place buses?

• Ten

• Twelve

• Fourteen

• Sixteen

What is the importance of using a modeled drawing in two-step questions?

• It eliminates the need for calculations

• It guarantees the correct answer

• It provides a visual aid to understand the problem

• It simplifies the problem
