The idea, step by step
Days and weeks
Hours describe parts of a day. A day includes daytime and night-time.
Seven days make a week. They repeat in the same order.
| Day number | Day |
|---|---|
| 1 | Monday |
| 2 | Tuesday |
| 3 | Wednesday |
| 4 | Thursday |
| 5 | Friday |
| 6 | Saturday |
| 7 | Sunday |
Months and years
A month is a group of days on a calendar. Twelve named months make a year.
Not every month has the same number of days. A month is not exactly four weeks.
A common trap
A month is the same length as a week.
Instead: A week has seven days. A month has more days and its length can vary.
See the thinking
A birthday
Would you describe the time from one birthday to the next as one year or one hour?
- Birthdays are far apart.
- A year is the useful unit.
A club
A club meets every Tuesday. Is that a daily or weekly routine?
| Day number | Day |
|---|---|
| 1 | Monday |
| 2 | Tuesday |
| 3 | Wednesday |
| 4 | Thursday |
| 5 | Friday |
| 6 | Saturday |
| 7 | Sunday |
- Tuesday is one of the seven days.
- The next Tuesday is in the next week.
