It’s that time of year again and we can play the 2017 Year Game in our January lessons.
On Simon Job’s MathsClass, he suggests writing a number sentence under the date; as you can read on his blog he endeavoured to write the number sentence using the digits of the date in order in 2016. It strikes me this idea could be used as a starter, ask the students to come up with such a number sentence.
2017 is a prime number and as we see from the WolframAlpha properties below, in particular a Pythagorean prime, so another source of starters and investigations perhaps? The last time the Year was a Pythagorean prime was 1997.
We can also look at WolframAlpha which provides further information including what 2017 looks like in historical numeral forms. We could use the various WolframAlpha queries to learn how Babylonian, for example, numerals work. Some possible starters for January lessons here I think!
The Babylonian system was a positional base 60 system, though interestingly uses ‘units’ and ‘tens’ symbols to create the 59 symbols needed.
For more on the Babylonian system including how fractions were represented see History of Fractions from Nrich.
Wishing educators and students everywhere a very Happy New Year.
Resolutions for (Maths) teachers.
