A time span tells you how much time passes between two clock times.
Here is how:
1. Read the start time and the end time.
2. First count up to the next full hour, then continue in big steps.
3. Example: From 8:15 to 9:00 is 45 minutes.
The filled in number shows the answer.
Example
- 45
- 30
For parents
What does this exercise practice?
This exercise trains calculating with clock times and prepares for planning with hours and minutes in everyday life.
Common pitfalls
Children often calculate with clock times like ordinary numbers, for example 9:00 minus 8:15 equals 85. It helps to use the step via the full hour, first counting up to 9:00 and then continuing.
How to practice at home
While cooking or before bedtime, ask how many minutes are left until a certain time.
