Time is invisible, which makes it the strangest thing a Year 1 child is asked to measure. Yet every conversation about time really asks one of two questions. How long did it take? That is duration. And when did it happen, before or after what? That is sequence. This unit gives children the words for both, using the everyday containers the curriculum names: years, months, weeks, days and hours. The big secret is that these containers nest inside one another like boxes inside boxes — hours fill a day, days fill a week, weeks fill a month, months fill a year — and once a child can climb up and down that ladder, time stops being a fog and becomes a place where events can be filed.
Boxes inside boxes
Time comes in containers: hours in days, days in weeks, weeks in months, months in a year.
Zoom in and watch each container open into the next.
Boxes inside boxes
The nesting is worth saying out loud, with numbers attached: 24 hours make a day, 7 days make a week, about 4 weeks make a month, 12 months make a year. Children do not need to memorise these as a chant; they need to feel the zoom — that a year is not a different kind of thing from an hour, just a much bigger box holding many smaller ones. That single picture quietly organises every calendar they will ever read.
The week wheel
Days do not run out — they go around. Spin forwards and backwards.
Today is Monday. Tomorrow will be Tueday.
The week is a loop
Days of the week are a child’s first experience of a cycle: the sequence never ends, it comes around. After Sunday there is no edge to fall off — Monday simply returns, seven sleeps after the last one. Practising tomorrow and yesterday in both directions builds the flexible movement along the cycle that reading a calendar quietly demands, and it plants the word week as a thing with a fixed, countable size.
How long does it take?
Every event has a size of time that suits it. File each one on the right shelf.
Pick the size of time that fits the event.
Every event has a size
Duration becomes manageable when events are matched to the container that suits them. A footy match lives inside hours; a beach weekend inside days; school holidays inside weeks; summer inside months; and the wait from one birthday to the next fills a whole year. Sorting events this way is estimation, not precision — exactly the skill the curriculum wants at this age, and a child who argues about whether holidays are weeks or months is doing real mathematics.
Order the day
Tap the events in the order they happen, morning to night.
What happens first?
Before, after, and in between
Sequence inside a single day runs on hours. Waking up, the start of school, footy training, bedtime — each event owns an hour, and the hours give the day its fixed order. Children often know the order of their day by feel; pinning each event to a clock number turns that feeling into something they can say, compare and defend: school starts after breakfast because nine comes after seven.
The year track
Twelve months in order — with the seasons the Australian way around.
Jan is summer — and it brings School starts.
The Australian year
The months run January to December everywhere on Earth, but the seasons riding on them are upside down here: Christmas lands in summer, the winter break sits in July, and the new school year begins when the days are longest. This is worth celebrating rather than footnoting — an Australian child who can walk the year track, naming months, seasons and the events that hang from them, owns their own calendar rather than a borrowed one.
