Discussion  -

Been a while since I posted anything so here is a video I did this morning. Using the very cheap off the shelf syma x5c. I will bring it along to the next meeting.

Nice day for it Michael! Is there an upgrade on the horizon?﻿

Geometry  -

It is pi day tomorrow, if you are talking about this incredible number in schools then you might want to check out
http://www.visnos.com/demos/pi

It shows in a very visual way of getting an approximation of the number using the perimeter of a polygon. As the number of sides increase the polygon will approximate to a circle. The nice bit is the polygon can be opened out to become a straight line, this can be measured against a ruler to show the value.

As it is based on animations I think most age groups can take something away from the activity.

Number & Operation  -

Teaching multiplication tables, this interactive teaching resource is great for showing each value as well as explaining various patterns. Animated fish make it a fun and visual way to learn.

http://www.visnos.com/demos/sieve-of-eratosthenes

I thought Mathematics community might like to check this out, there are other versions on the web. But they tend to be old, flash or java based. This one using html5 will work on an iPad or smartphone.

Also it allows more than one colour on a square, so when a sieve is complete it is possible to see the prime factors of each number by the colours on its square.

Any feedback and I would love to hear, as I designed it.

Thanks.﻿
The Sieve of Eratosthenes is an ancient way of finding prime numbers. It is useful for exploring multiples factors and primes.

Thanks, glad you like it!  You are of course right the search can stop in auto mode at the square root of the grid size. I can update the code when I fix the animation speed.﻿

This Months meeting has been wrongly advertised for tomorrow(13th May).

The meetup will be on the third Tuesday as always, which this month will be the 20th May.

Apologies to anyone affected.﻿

I don’t know about you, but I cringe when I lose a lens cap. So I can't imagine how Christ Newman of CineChopper felt when he lost, not a measly lens cap o

The reason comes from the way the date is formatted in the USA. The month comes first followed by the day, this gives March 14th as 3.14 omitting the year.

Hence Pi day was founded. If you use a more logical system of day/month/year then it doesn't make much sense. ﻿

I only have a few photos from the meetings, if anyone has any good ones I will add them to the meetup site.﻿

yes it might be an idea﻿
