Today marks the beginning of the River Houses year and the beginning of our Fall Term — Cygnus Term — which runs from September through November.
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 a great many 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 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 a new and open-ended idea that we’re developing for the River Houses, and we think has a great deal of educational potential. We’re looking forward to its elaboration 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 three-month 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 at the beginning of each term to see how the seasons change. You could group your curricular work by term, or set goals at the beginning of each term that you want your students to meet. You could have your students measure their height and weight 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.
Today is the first day of Cygnus Term, named for the Great Swan of the Heavens that is high in the east at sunset now each evening, and that will be passing overhead to the west as the fall comes on. Your students’ vocabulary word for the day is “cygnet.” 😊 And be sure to take note of the scientific names of the earthly swans on page 22 in your homeschool bird guide.
If you want to make a special astronomical study this Cygnus Term, your River Houses reference library (riverhouses.org/books) includes an excellent little guide to the night sky that will show you the location of Cygnus and its most prominent stars:
“Cygnus lies in what for observers is a dense and fascinating part of the sky. The bird’s wings span the Milky Way at a location packed with stars and an assortment of deep-sky objects. Owing to the positions of its brightest stars it is sometimes called the Northern Cross — the northern parallel to the Southern Cross constellation in the Southern Hemisphere. You will see Cygnus highest in the sky in late summer and early fall, with its head pointing south like a bird on its migratory path toward warmer climates.
“A thick band of dust lies within Cygnus, creating a dark space in the Milky Way that is easily visible to the naked eye under good conditions. This part of the Milky Way is known as the Cygnus Rift or the Northern Coalsack, a name borrowed from a similar dark spot found in the Southern Cross.“ (National Geographic Backyard Guide to the Night Sky, page 216)
Why not spend a little time out after dark with your students over the next three months and locate the Great Swan as it makes its nightly migratory flight 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 Cygnus 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 natural arrangement so that our River Houses calendar will align more conveniently with the ordinary months and with the more-or-less customary American school year. In many traditional calendrical systems, going back into the Middle Ages, the first day of each quarter is called a quarter day and the midpoint of each quarter is called a 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 15 October, 15 January, 15 April, and 15 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 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 astronomy 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 spheres. Find a dark-sky spot near you this term and spend some quality homeschool time beneath the starry vault. 🔭
