Two-Step Word Problem Solving with Number Lines

This video tutorial teaches how to solve two-step word problems using a number line. It begins with an example involving Jeremiah's paper, demonstrating the use of a ruler as a number line to perform addition and subtraction. The tutorial highlights common misunderstandings, emphasizing the importance of sequential operations. Another example with Kim's popcorn problem further illustrates the concept. The lesson concludes by reinforcing the method of solving two-step problems with a number line.

What is the first step in solving a two-step word problem?

• Use a calculator

• Write down the final answer

• Underline important information

• Guess the answer

In the example with Jeremiah's paper, what operation is performed first?

• Multiply by 2

• Divide by 2

• Subtract 8 inches

• Add 6 inches

Why is it important not to perform all operations from the starting point in two-step problems?

• It leads to incorrect results

• It is faster

• It is easier to remember

• It makes the problem more complex

What is the initial number of popcorn kernels in Kim's bag?

• 13

• 28

• 80

• 43

How many kernels did Kim eat?

• 80

• 43

• 13

• 28

What is the final number of kernels left in Kim's bag?

• 43

• 80

• 67

• 24

How is the number 24 broken down for easier subtraction in the popcorn problem?

• Two groups of 10 and a group of 4

• Three groups of 8

• Four groups of 6

• One group of 20 and a group of 4
