Telling Time- Duration Quarter Hour

Elapsed Time — Quarter Hours

Practice finding new times in 15-minute steps with natural questions like “It is 3:15. What time will it be in 1¼ hours?” and “It is 7:45. What time was it 2¾ hours ago?”

⭐ Student Tips

• A quarter hour = 15 minutes.

• “Will it be in …” → add the time. “Was it … ago” → subtract.

• Watch the hour hand move as minutes pass; it creeps between numbers.

• Wrap around after 12 (e.g., 11:45 plus 45 minutes → 12:30).

📘 Teaching Instruction

• Model elapsed time with 15-minute jumps on a clock or number line.

• Use start times at :00, :15, :30, :45 to highlight quarter positions.

• Have students say the amount using mixed fractions: ¼, ½, ¾, etc.

• Mix hour-only, half-hour, and quarter-hour problems for spiral review
