Original Text: The video “Against the Clock” shows how events were timed in the Summer Olympics, held in London 2012.
How are events timed? (High-definition cameras and clocks, lasers, and computers time events in milliseconds, which are one-thousandths of a second.)
How close was Michael Phelps’s score to the silver medalist’s in winning the gold medal in swimming? (one-hundredth of a second)
How has timing changed over the years? (from one-tenth of a second to one-hundredth to onethousandth of a second)
To find out who has the fastest time in a race, the judges need to know how to compare decimals, often decimals that are close in value.
Updated Text: The video “Against the Clock” shows how a sports trainer trains an athletic swimmer for the Paralympic Games.
What technology does the sports trainer use to train Momo? (The trainer uses wearable technology and touchpads.)
How close was Momo best training time to the qualifying time for the para-nationals 100m freestyle event? (three and seventy-four hundredths of a second)
To find out who has the fastest time in a race, the judges need to know how to compare decimals,
often decimals that are close in value.

Original Text: The video shows that it’s a race against time to get a heart to a transplant patient. Every fraction of a minute counts.
Help students relate fractions to precision.
■ How are fractions used to describe the race against the clock to get the heart to the hospital? (The doctors talk about the number of hours they had to get the heart from the donor to the patient.)
■ What are some other ways fractions are used in the video? (to describe how long a person might live after receiving a transplant)
To find out how much time there is left to deliver a heart to a patient, we need to use subtraction.
Updated Text: The video shows how doctors compare fractions to determine the treatment for patients.
Help students relate fractions to precision.
How are fractions used to decide if a patient has a narrowing in the coronary artery? (The doctors compare the widths of the normal artery and the narrowed artery to calculate the fraction representing the difference between the two widths.)
What are some other ways fractions are used in the video? (to determine what treatment the patient needs to help the narrowing)
To find the size of the narrowing, doctors must compare and then subtract to find the difference in the narrowing.
Original Text: This problem asks us to compare the number of videos that Dana, Hayley, and Juan post online. The phrase “3 times as many” tells us that it is a compare problem.
Let’s draw 3 bars and use what we know to compare the 3 quantities. How many videos does Dana post? (7) How many equal parts are in the second and third bars? (3; 6, twice the size of the second bar)
The bar model shows us that Juan has 6 times as many videos as Dana. What is 6 × 7? (42) So, Juan posts 42 videos.
Updated Text: This problem asks us to compare the number of books that Dana, Hayley, and Juan read. The phrase “3 times as many” tells us that it is a compare problem.
