Adding & Subtracting Time, 15-Min Intervals

Overview:

An activity designed to help students add and subtract elapsed times in 15-minute intervals, writing the new times in both analogue and digital formats. Designed for middle years students.

Learning Objectives:

• Add and subtract elapsed times in 15-minute intervals.
• Write the new times in both analogue and digital formats.
• Strengthen skills in working with time calculations, focusing on smaller intervals.

How the Activity Works:

Students are given start times and elapsed times. They add or subtract the elapsed time (in 15-minute intervals) to determine the new times. The new times are written in both analogue and digital formats. This activity helps students practise time calculations and gain confidence in working with different time representations.
