Today is the beginning our winter term in the River Houses — Orion Term — named for the Great Hunter of the Heavens. Orion Term runs from December through February.
We put great stock in the educational value of the calendar in the River Houses. The calendar is the framework on which we human beings hang most of the facts we know about the world: historical events, natural phenomena, personal reminiscences, the seasons, blooming flowers, migrating birds, the sun and moon, the planets, the stars. A key part of every student’s intellectual development is the development of “calendar sense” — a sense of time and history.
Our annual River Houses calendar (riverhouses.org/calendars) divides the homeschool year into four three-month terms (quarters) that roughly correspond to the seasons, and these terms are named after prominent seasonal constellations of the northern hemisphere:
- 🗓 🦢 Fall or Cygnus Term (September–November)
- 🗓 🗡 Winter or Orion Term (December–February)
- 🗓 🦁 Spring or Leo Term (March–May)
- 🗓 💪 Summer or Hercules Term (June–August)
This calendrical division is an open-ended idea that we’ve developed for the River Houses, and we think has a great deal of educational potential. We’re looking forward to expanding upon it as time goes on.
As you think about your own homeschool year, think about how different parts of it — curricular, co-curricular, social, or recreational — might be informally arranged into these four terms. You could have a different decorating theme in your classroom each term, for example, or you could schedule a regular trip to a special place where you take a photo at the beginning of each term to track how the seasons change. You could group your curricular work by term, or bake a quarterly cake, or set goals at the beginning of each term that you want your students to have met by the end. You could have your students measure their height at the beginning of each term, or take their penny-jar to the bank for a quarterly deposit. At the end of each term you could assemble a portfolio of student accomplishments. With a little imagination you will be able to come up with a clever and comfortable arrangement and a new way to think about the structure of your educational year.
Orion Term is named for the Great Hunter of the Heavens who is rising in the east every evening now and who will be passing overhead throughout the winter. Orion Term is home to our special Holiday Music Month (the month of December); to the Winter Solstice (21 December), Christmas (25 December), and New Year’s Day (1 January); to Twelfth Night (5 January), Martin Luther King Day (18 January), and Mozart’s Birthday (27 January); to Lincoln’s and Darwin’s Birthday (12 February), Valentine’s Day (14 February), the Great Backyard Bird Count (12–15 February), and Washington’s Birthday (15 February) — not to mention countless other holidays, anniversaries, and events, local and global, public and private, that you may wish to mark on your own homeschool calendar.
If you want to make a special astronomical study this Orion Term, your River Houses reference library (riverhouses.org/books) includes an excellent backyard guide to the night sky that will introduce you to Orion and its most prominent stars:
“[Orion] may be the most recognizable constellation in the sky, visible worldwide from its position straddling the celestial equator and identified by different cultures across thousands of years. Its prominence earned it three references in the Bible as well as mentions in The Iliad, The Odyssey, and other literary classics. To modern sky-watchers, the hunter’s position is ideal for use as a reference point: three of the sky’s 25 brightest stars are found in this group, and their brightness makes the structure of a man quite easy to see. The hunter’s bright belt is made of three stars, all around magnitude 2. His upraised, club-wielding arm sweeps into the Milky Way, while his other hand holds a shape interpreted as either a shield or a lion’s pelt.
“Orion’s main stars provide a way to orient yourself even amid the glare of city lights. Betelgeuse, the constellation’s alpha star [and our February star-of-the-month], represents one shoulder. This huge variable star pulsates to a diameter between 300 and 400 times the size of our sun. Blue-white Rigel, the hunter’s foot, is a supergiant, 57,000 times as bright as the sun.“ (National Geographic Backyard Guide to the Night Sky, pages 264–265)
Why not spend a little time out after dark with your students over the next three months and watch the Great Hunter as he makes his nightly passage to the west. Once you learn to spot him, you’ll have a friend for life.
What educational adventures do you and your homescholars have planned for this Orion Term? 😊
❡ Quarter days and cross-quarter days: Dividing the year into quarters is an ancient and natural practice: the annual movement of the sun across the sky automatically gives us two equinoxes, two solstices, and four seasons. Our four terms are just a simple modification of that arrangement so that our River Houses calendar will align more conveniently with the ordinary months — with the “meteorological seasons” rather than the astronomical seasons — and with the customary American school year. In many traditional calendrical systems, going back into the Middle Ages, the first day of each quarter is called the quarter day and the midpoint of each quarter is called the cross-quarter day. That means the quarter days of the River Houses year are 1 September, 1 December, 1 March, and 1 June, and the cross-quarter days are 16 October, 14 January (15 January in Leap Years), 15 April, and 16 July. (Fun fact: a vestige of the old system of quarter and cross-quarter days is Groundhog Day, also known as Candlemas on the Christian calendar: it’s the cross-quarter day between the winter solstice and the spring equinox.) Quarter days have for centuries been the traditional days on which school terms began, so homeschoolers who follow our four-term River Houses calendar are participating in a very ancient tradition indeed. 🗓
❡ Watchers of the skies: Teaching your students to recognize the constellations is one of the simplest and most enduring gifts you can give them. Your recommended River Houses night-sky guide (riverhouses.org/books) has descriptions and maps of each constellation that point out the highlights, and the astronomical section of your recommended world atlas has beautiful large charts of both celestial hemispheres. Why not find a dark-sky spot near you this term and spend some quality homeschool time beneath the starry vault. 🔭
