Dates as Operations 2017

Wednesday, 28 December 2016 | 0 Comments

Like most teachers I write the date at the top of the whiteboard each day. As an extra point of interest, in 2016 I endeavoured to write a number sentence using the digits of the date, in order, underneath the date.

For example:
7/4/16        7 - √4 = -1 + 6
27/5/16        2 + 7 - 5 = √16
(Date written as dd/mm/yy)

  • Example of data as operation

I didn't specifically refer to the sentence, nor make it an activity in class. A senior student in one class made a point of completing the number sentence if I hadn't. Another student in my roll class regularly pointed out if I had not written a sentence for the day.

In 2016 I had some help completing a list of sentences.

If you'd like to contribute to a list for 2017 (or just use the list) visit this Google Sheet:

Dates as Operations 2017

For 2017, I have columns for two formats of the date dd/mm/yy and dd/mm/yyyy.
