It is 3:30. What time will it be in 2½ hours?
Elapsed Time — Half Hours
Practice finding new times using half-hour increments with questions like “It is 3:30. What time will it be in 2½ hours?” and “It is 7:00. What time was it 3½ hours ago?”
⭐ Student Tips
A half hour = 30 minutes.
Will it be in … → add that many hours/half-hours.
Was it … ago → subtract.
Remember to wrap past 12 (e.g., 11:30 in 2½ hours → 2:00).
📘 Teaching Instruction
Model with clock jumps of 30 minutes.
Use both o’clock and :30 start times.
Stress half-hour language: “2½ hours = 2 hours + 30 minutes.”
Spiral with hour-only and half-hour questions for fluency.
