Summary: Case Analysis
Math Case Study
MCC2.MD.7: Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.
Work/Test Sample Analyses*
Work Sample 1:
This is a sample of a morning work assignment Mark was given upon arrival to the classroom. After completing the sheet, students glue them into their Math Journals and justify their answer for a problem of their choice. The work shows an analog clock that is displaying 8:00 on its face. The question asks, “what time is shown?” Mark answered “8:00.”
Work Sample 2:
This sample is another excerpt from Mark’s morning work. The work shows an analog clock that is displaying 6:00 on its face. The question asks, “what time is shown?” Mark answered “6:00.”
Work Sample 3:

The first clock displays 7:15. The second clock displays 6:35. The third clock displays 2:05. For the first clock, Mark wrote, “15:35.” For the second clock, Mark wrote, “35:30.” For the third clock, Mark wrote, “5:10.” All three answers are incorrect. In all three problems, Mark uses the minute values only. He also writes what would be the minute value before what would be the hour value. The next section asks, “Which clock shows 12:00?” Underneath the questions are four digital clock choices. The choices are A) 6:00, B) 12:30, C) 6:30, and D) 12:00. Mark selected option A. The displays on the digital clocks are dark, so I wonder if he had trouble reading the displayed times. The third section has two questions where the student must indicate if an even happens in the a.m. or the p.m. The first question asks, “When do you have your breakfast?” Mark selected p.m. The second question asks, “When do you watch TV after dinner?” Mark selected p.m., which is correct.

In this game, the player must help the character, Marvin, travel through time to find his friend. The player can choose to use an analog clock or a digital clock and make whichever clock they choose display the requested time. There are four stages to this game. The first stage gives times that are “on the hour,” such as 7:00 and 3:00. The second stage gives minute values in increments of five, such as 9:05 and 12:45. The third stage gives statements like “make it 15 of 12” or “make it 25 past 3.” The fourth stage also uses the of/past wording, but uses quarter and half increments. Some example phrases from this stage would be “make it half past 5” or “make it a quarter to 6.” Players must be careful, because the clock moves in increments of a minute; if you are a minute off, you get the question
