1Five seasons in a year is a repeating cycle
The chapter’s five seasons come, then the first returns next year. That restart is the cycle.
A season list that never restarts is not this year-cycle.
Figure. Five seasons come in a ring. After Winter the first name, Spring, returns — that restart is the year-cycle. A list that never comes back is not this cycle.
How it works
- Name the local fiveThe ones the chapter uses.
- See the first returnNext year.
- Call that a cycleLonger than a day.
2Spring, summer, and the rest keep an order
The seasons have an order. Summer does not sit before spring in this cycle.
Swapping two seasons breaks the year-sentence.
Figure. The five names keep an order. Summer does not sit before Spring in this year. After Winter the arrow returns to Spring.
How it works
- Say the firstSpring, if that is the chapter’s start.
- Keep the given orderNo swap.
- End, then restartThe cycle.
3A season is a stretch of months, not one day
Summer is many days. One hot afternoon is not “the season”.
A day can feel like summer and still sit in another season’s month. The stretch is the season.
Figure. Summer is a stretch of months on the year line. One hot afternoon is a day-mark, not the season. Keep the stretch and the single day apart.
How it works
- Name months in that seasonA stretch.
- Refuse one afternoonNot the whole season.
- Keep day and season apartTwo different lengths.
4Days, weeks, months on a calendar
A week is 7 days. A month is a named block of days on the calendar. Those are table facts you can look up.
Do not invent an 8-day week for a story.
Figure. A week is seven named days on the calendar. Wednesday is one cell in that row. Do not invent an eight-day week.
How it works
- Find todayOn the calendar.
- Count 7 daysThat is a week.
- See the month nameA longer block.
5Yesterday and tomorrow sit on that table
Yesterday is one day back. Tomorrow is one day forward. Afternoon today is still today.
The calendar line is the test, not a mood.
Figure. Yesterday is one day back from Today. Tomorrow is one day forward. Afternoon today is still Today — the calendar cells, not a mood.
How it works
- Stand on todayThe date you are in.
- One step backYesterday.
- One step forwardTomorrow.
6Duration is how long, not what time
A season lasts months. A song lasts minutes. Duration is “how long”. Clock time is “when”.
Do not answer “how long” with “4 o’clock”.
Figure. Duration answers how long: a season lasts months. Clock time answers when: 3 o'clock. Do not answer a how-long question with a clock hour.
How it works
- Hear the askHow long, or when?
- How long is durationShorter or longer.
- When is a clock or calendar markA different question.
7A clock hour hand and minute hand
The short hand is the hour. The long hand is the minutes. Reading the long hand as the hour flips the day-sentence.
This class names the two hands. Fine minute arithmetic can stay small.
Figure. The short hand is the hour. The long hand is the minutes. At 3 o'clock the short hand points at 3 and the long hand points at 12. Swapping the hands flips the sentence.
How it works
- Find the short handHour.
- Find the long handMinutes.
- Do not swap themTwo jobs.
8The poem names the cycle; the calendar stores it
A season poem is a memory hook. The calendar is the store of days and months. Do not treat the poem as the date.
Check a date on the table, not in the rhyme alone.
Figure. A season poem is a memory hook for the cycle. The calendar stores the date. Check a date on the calendar table, not in the rhyme alone.
How it works
- Enjoy the poemIt names the cycle.
- Find the date on the calendarThe store.
- Keep the two jobsHook, and table.
One hot afternoon is
- Not the whole season
- The same as summer
- A week
A season is a stretch of months.
Notes
- The official chapter title is “Which Season is it? (Measurement of Time)”. Teach the school test for that title, not a contest shortcut.
- If a step needs a later class, stop. The next official chapter will pick it up.
