Cultural Literacy: Zero-Sum Game

I’m not sure it it’s something high-schoolers need to know, though I’ll confess that I would have liked to have known about the concept of the zero-sum game as an adolescent. There is a Cultural Literacy worksheet under that hyperlink on the zero-sum game.

Two Basic Worksheets for Subtraction

Now, as it happens, I am not teaching math after all. So, I have a few more things I can post that I developed as I worked toward building a scaffolded curriculum for the basic operations. These two basic subtraction worksheets are the first of four more posts I’ll publish containing these materials.

365 Days of Haab

365 Days of Haab: The Mayan solar calendar was divided into eighteen twenty-day months (vigesimal notation). This produced 360 days, or one tun. In common with many religious calendars of the world, the shortfall of five extra days added on to make the 365 days of the solar year was a spirit-haunted period of ill omen, the five nameless Wayab days.

The habit of multiplying by 20 continued beyond the year, so that twenty tun (almost a solar year) is a katun, which was a great unit of time commemorated with inscribed standing stones and pyramid temples. Twenty katuns produced a baktun and twenty baktuns produce a piktun of 7,885 solar years. We have not quite got to a piktun, though quite recently, at the winter solstice of 2012, we celebrated the completion of thirteen baktuns which some observers too to be a possible date for the end of the world. The thirteen-baktun date (21-12-2012), which was safely achieved, begins by starting the calendar back at Year One in 3113 BC.”

The Mayan Calendar’s 52-Year Cycle

The Mayan Calendar’s 52-Year Cycle: The Mayan’s fifty-two-year cycle is created by observing how the combination of their two simultaneous calendars—the 260-day-long Tzolk’in fertility calendars and 365-day-long Haab solar year—fitted into a naturally repeating cycle over a fifty-two year time span.”
