Meeting on Friday 23th November, 1pm-3pm at Kenilworth Methodist Church, Station Road.

Cost 4 pounds per family.

As usual, we'll have Liverpool fun maths road show materials, puzzles, games, origami, colouring, and Marco's sessions for 4-6, 7-9, and 10+.

Additional theme for meeting: coding, including Ceaser Cipher, and "Logo" type instructions for drawing pictures

Materials created for the meeting

• Ceaser cipher wheel to cut out. Ask if you need a split pin - I have lots left!
• Ceaser cipher sheet
• More secret messages to decode
• Archimedes box, and Archimedes box handout - see below for lots more links on this
• coded pictures sheet
• Hand out about the club for this meeting

Links to material used in meeting

Material in room 1/2

• A few links on secret codes - there are very many more!
  • An encryption program
  • CIA kids page
  • Bletchley park - somewhere to visit
• links on Spirograph - there are lots of other links on this!
  • from the Nrich site on a 50p version
  • on the planets, from Nrich. This also includes instructions for making a very quick and easy simple spirograph at home. We glued on the rubber band, since otherwise it kept falling off. We found it works really well.
  • I did think about other methods of making a spirograph, like this one, but the corrugaged card we had (from some packaging) didn't work very well, so I gave up on that idea, but let me know if you try and it works! We just decided to buy a set for the meeting, hope it will get lots of use at future meetings, but won't bring it every time - but let us know if you want to see it again, or if you want to borrow it! Whatever is popular can come more often!
  • Lots of pages on line about spirograph and guilloche patters. There are even pictures of a human spirograph!
• links on Archimedes box
  • part of Geometric Dissections by Mircea Pitici
  • Online version of the puzzle
  • video of solutions
  • Even more and more on this puzzle... and there are lots of other site on it, not to mention that you can buy it.. I got interested in it after seeing a beautiful crafted bone and wood version at a reenactors market in Ryton.
• links on prime numbers and Sieve of Eratosthenes
  • Sieve of Eratosthenes for finding prime numbers. Lots of pages on this online, see e.g. wikipedia page on Sieve of Eratosthenes
• At the meeting I put out the following Liverpool fun maths roadshow puzzles: QQ, TT, WW, YY, C, G, I, K, R, S, Y, W; 29, 31, 33, 41, 46, 73, 76, 81, 84, 86, 89, 94, 96, 98, 167, 156, 163, 165, 169

Material in room 3 for Marco's sessions

• 4-6 and 7-9 did a measuring activity using string - the idea from Games for maths
  This used graph paper - you can print out your own here , or lots of other sites, if you don't have it, but it's easy to find in stationary shops, or places like Wilko's
• 7-9 used the coding wheel - see links above
• 10+ did the 27 card trick again, and also the 16 card trick and started learning about binary numbers. This is based on Peter Taylors explanation, though his goes quite a bit further to more general cases. There are also lots of other pages about this online.
  They also played a clock game for 2 players - start at 6o'clock, you move either 2 or 3 hours. First to exactly 12 o'clock wins (you might need to go several times round) see if you can come up with a strategy for next time!
  They also started learning about primes - see links on Sieve of Eratosthenes above.
