I love the suggestions of 31st April and 3rd of Dodecember. Thanks also for the information about the Chinese characters - didn't know that. Great to talk about with our Chinese background students too. I agree wholeheartedly with your concerns, so hope you won't think I've missed the point, but there is something that is definitely worth a pi fight over and that is "pi approximation day"! In Australia we always celebrated 'pi day' on the 22nd of July (22/7 for us) but apparently the US legal declaration of 3/14 as 'national pi day' has somehow managed to make it 'international pi day', with a passing reference on some US sites to 'pi approximation day' for 22/7. Surely this implies that 3.14 isn't an approximation!! Especially when 22/7 closer! <br />I live with the hope that pi day discussions could at least look at a comparison of the two. It's certainly more likely to happen if your suggestions are followed. Students could compare their measured and calculated table of results to both. <br /><br />(By the way, how many teachers do you think might allow their students to calculate the decimal value of their ratio with a calculator, without any discussion of the rounding or truncating that is involved with that too! Another reason I like 22/7 - sevenths take a reasonable amount of calculation before they start to repeat.)<br />kay kirkpatricknoreply@blogger.comtag:blogger.com,1999:blog-6172532982347376290.post-30116964177622461962013-03-25T10:42:04.990-04:002013-03-25T10:42:04.990-04:00So you don't celebrate square root of two day,...So you don't celebrate square root of two day, either, on Jan. 24 (24/1) ? You just won't let people force rationality on you...SiouxGeonzhttps://www.blogger.com/profile/14852040976080951492noreply@blogger.com
