Preschool unit plans: a theme week and a year by season
Published 2026-10-16 · Updated 2026-10-16
A preschool unit plan at home is one nearby topic held for several days, with a beginning, a middle, and an end. A year of units can follow the seasons, and you can swap in an everyday topic (weather, plants, animals, senses, people) when the season's idea does not fit your street. Write the unit as a week page, then do it with one child.
A home unit is one nearby topic
Illinois Early Learning says preschoolers like to investigate things nearby that interest them, and that projects are like good stories with three parts: a beginning, a middle, and an end. The sheet is written for preschoolers from age 3 through age 5. At home, you are the guide. Your child can still pick the leaf, the truck, or the puddle.
A unit is not a new craft every morning. It is the same topic seen again: notice it, look closer, then show someone what you noticed. The week page that holds those days is a lesson plan. The steps for writing that page are in preschool lesson plans.
Keep each sit-down short. The CDC five-year checklist includes paying attention for 5 to 10 minutes during activities such as story time or crafts, and the example sets screen time aside (milestones by 5 years). A three-year-old may leave before that. Follow them to the window and keep the topic.
Beginning, middle, and ending
Use Illinois's three phases as the skeleton, in home language.
Beginning. Walk to the topic or bring it to the table. Ask what your child already notices. You can write two words they say. Illinois's first phase is children talking about what they already know, and listing questions, with the adult writing those ideas down. One question is enough: "Where did the leaf fall from?"
Middle. Look again on another day. Count something, sort two piles, or draw what you see. Illinois's middle phase includes drawings, labels, and graphs of things children measured and counted. At home, a tally of red leaves versus brown leaves is a graph. Books you already own can sit beside the real object. Illinois mentions books as one way children collect information, with an adult's help.
Ending. Show the drawing to someone who was not on the walk, or tell them one thing you saw. Illinois's last phase is children deciding how to show what they found, including drawings and a short telling. A fridge picture is a display.
If your child asks a question you cannot answer, write it on the page and look together later. You do not need a field trip.
Themes by season
Illinois's seasons note says children see changes, and they may not yet have a sense of the four seasons or that the seasons cycle every year. Fall is a time to talk about leaves changing color and dropping, mornings becoming cooler, and night arriving earlier. The same note suggests photos of trees in summer and in fall, then more photos for winter and spring, so you can talk about before and after, and about same and different.
A year of home themes can follow that cycle. These are planning ideas, not a required sequence. Skip any row that does not match your weather or your family.
| Season | Nearby themes | What to look at |
|---|---|---|
| Autumn | Leaves, harvest food, apples, cooler mornings | A tree you pass, a pumpkin or an apple you can cut with a grown-up knife |
| Winter | Lights, cold, birds at a feeder, indoor shadows | A window, a mitten, a lamp you switch on at dusk |
| Spring | Rain, seeds, insects starting to appear, puddles | A pot of soil, a sidewalk crack, a worm after rain |
| Summer | Water, picnic food, long evenings, a park | A cup of water, a blanket outside, a cloud |
Same and different is the talk Illinois suggests on a leaf walk: some trees stay green, others change. Before and after fits a day: before the sun goes down, walk; after it is dark, play inside. A photo of the same tree in two seasons is enough. You do not need a classroom calendar.
Holiday weeks can stay small. A winter lights week can be "we turn on a lamp and draw the window." A summer picnic week can be "we eat outside and count cups." If a holiday is not part of your home, use the season's weather instead.
Everyday topics you can swap in
Season themes run out, or the weather does not match the month. Swap in a topic your child can see this week:
- Weather: puddles, wind, a coat.
- Plants and seeds: a houseplant, a potato eye, grass.
- Insects and birds: one bug on a step, birds at a feeder. Look, do not catch a bee.
- Farm or ocean: pictures in a book if you cannot visit, or a trip if you can.
- Five senses: what the apple smells like, what the mitten feels like.
- Feelings and friends: who we waved to, what face we make when we are glad.
Science-leaning rows such as plants, insects, and weather have more household tries on preschool science activities. A paper craft for the ending day can come from art and craft activities for preschool.
Cutting fruit or using small nature finds needs you at the table. Pieces of toys, and small objects a child can reach, are choking hazards on the American Academy of Pediatrics page, which says most children who die from choking are under age 5 (choking prevention). Put acorns and beads away when you stand up.
How long to stay on one theme
Stay until the ending happens, often a handful of days, then change. If your child is still asking about the mailbox on Friday, keep the mailbox next week. If they are done on Wednesday, start the next topic. A unit plan that you abandon is still useful: you learned the topic was too far from your street.
The CDC milestone lists are things most children (75% or more) can do by a given age, and they are not a screening tool (milestones by 5 years). A finished unit does not show that your child is ready for a classroom. That is the honest limit of a theme week: it organizes what you do, and it does not grade the child.
A sample leaf week (illustrative)
This leaf week is illustrative. The counts are invented so the shape is visible.
Monday: walk to one tree. Child points at a yellow leaf. You write "yellow." Tuesday: sort five leaves into two piles, same color and different color. Wednesday: draw the tree. You label "leaf" if your child asks. Thursday: count steps home. Stop at ten even if the walk is longer. Friday: show the drawing to a grandparent on a call, or to someone in the kitchen.
Easier option any day: you hold the leaf, child says one word, you write it.
Printed theme weeks, if you want them
You can run the seasonal list with paper you already have. If you want twelve theme weeks already written in the same day-by-day shape, Theme Unit Library: 12 preschool units adds a theme week through the year for a 3 to 5 year old, each unit planned day by day. It includes 12 theme units: autumn and harvest, winter lights, spring and Valentine's Day friendship cards, summer and Fourth of July picnic, weather, plants and seeds, insects, birds, ocean, farm, five senses, feelings and friends, and each unit has a 5-day unit guide with easier options and a print-and-gather list. Holiday units are secular and simple; they do not teach religion. You print the pages; nothing is shipped. An adult supervises scissors and small items.
