Question Correct Answer Standard Explanation/Key Detail 1 A NC.3.MD.1 The time shown is 3:42. (Hour hand just past 3, minute hand on 42nd mark). 2 B NC.3.MD.2 52 - 15 = 37 minutes elapsed time. 3 A NC.3.MD.3 A standard large soda bottle is 2 liters. 4 C NC.3.MD.3 A dictionary is heavy, making 2 kilograms (approx 4.4 lbs) the best estimate. 5 C NC.3.MD.4 Blue (12) - Yellow (4) = 8 more students. 6 A NC.3.MD.1 The clock shows 10:07. (Hour hand just past 10, minute hand at the 7 min mark).

01
Elapsed Time (NC.3.MD.2)
Final Time: 2:05 PM
Step 1: Start at 1:17. Add 43 minutes to get to the next hour (2:00).
Step 2: 48 total minutes - 43 used minutes = 5 minutes remaining.
Step 3: 2:00 + 5 minutes = 2:05 PM.
02
Liquid Volume (NC.3.MD.3)
Remaining: 353 mL
Step 1 (Add used): 235 mL + 312 mL = 547 mL used total.
Step 2 (Subtract from total): 900 mL - 547 mL = 353 mL remaining.
03
Mass (NC.3.MD.3)
Mass of rock: 8 kg
Calculation: 32 kg ÷ 4 rocks = 8 kg per rock.
04
Data & Bonus (NC.3.MD.4)
Graph Check:
Title should be something like "Mass of Soil Samples"
Bars must reach: Sandy (15), Clay (25), Loam (10), Peat (20)
Bonus Answer: 20g
Group 1 (Clay + Peat): 25g + 20g = 45g
Group 2 (Sandy + Loam): 15g + 10g = 25g
Difference: 45g - 25g = 20g
Note for Teachers: For Problem 4, ensure students have correctly utilized the scale of 5g per interval provided in the graph template. Partial credit may be awarded for correct group addition in the bonus even if the final subtraction is incorrect.
