Minutes+from+May+2nd+and+updates+from+Ian+Roberts

Here is a summary from our last saturday meeting (May 2). It is a working document with lots of brevity and lots of our names. Is it correct? The aim is to get it into a reasonable shape by early next week. I have to interact with each World leader to sort out preparation of the problems in each World. Contact me directly if you wish. Please note the names attached to each item mentioned in the summary and realise that it means it is your responsibility, unless you negotiate otherwise and let us all know. Ian
 * Summary of May 2 meeting**

Sketch of ideas from meeting Saturday March 2nd 2009. **Program** Ian R, distributed preparation of materials conforming to a Skeleton setout. See responsibilities below. Idea is to be consistent in presentation between rooms so the kids need minimal instruction. Partial Exception: robots, thinking worlds. Ian R to distribute ideas to groups for their preparation in laison with ian r. Teachers are expected to have a sense of the problems, but not necessarily how to do them. We are not there to instruct or hint at approaches. This will be done through material provided. Kids can talk to ian r but still no solutions given. Kids can choose their problems to follow and spend as much time as they like. If they can’t do/don’t like a problem then try another. Showing staffing – always at least one per world Question: name of ‘rooms’, world, station, …? Any good ideas? 5 worlds, 5 activities:
 * 5 Enrichment worlds CROPT**
 * Robot** world: John, Derek,
 * Outdoor** world: paths, cycles, centres, Steiner tree (4 points in rectangle to be joined with min amount of chord). We know exact answer, see what kids do. Need witches hats or similar, rope or similar, tape measures, hammer, nails, blocks of wood, bucket of soapy water. Matt, Michele
 * Thinking/quiet** world. General problems such as 1989. safety/supervision if not in a room. Calculators available here only and not to be removed. Otherwise they can use phone calculator. Roger
 * Colouring** world. colour/number problems. Caroline, Leah, Val
 * Problem**, (Logic, Calculating) world. Mick, Pat

Need notes to teachers – their role. Try 1 or 2 teachers per room out of 3 – these know the basic topics, don’t teach but encourage or manage/slight hints at most. Need teachers to cruise around and note any issues that may be arising. Sat2/5 teachers split into groups to prepare activities and email to me to check/comment. Want standard format. Ian R, Caroline for format. __**Friday**__: mix of get to know you activities. (Pat or Donna 10 kids each hold hand of 2 others – untwine), Hi5s, HT game – students choose by standing and showing head/tails with hands, throw dice and sit down if wrong. A pass the parcel variant, with questions wrapped – last one standing correct or fastest group to finish or ?, maybe they work out how many to pass it so they all get a go once – rules, not adjacent person, always same amount in same direction. ) maths, quizzes, introduce 1989 problem (Ian R get sheet from Jeanette v) and overview. Each kid follows own path in the problems they choose to work on. Discover: which problem is related to the logo?
 * Floating staff**: Ian R, Ian S, Chris R, Heleana W, Sandra
 * Enrichment program overview**

__**Saturday**__: Quick activities between sessions, small prizes. Prizes and certificates presented Sunday. Teams or individuals they choose.

Ideas for activities: theme **Graphs**

One introductory lesson/notes then rooms. Graph of rooms. Allow a second visit to a room that they like.

Sheets with motivation, background, instructions, pictures, examples, problems, partial hints at different levels gold silver bronze depending on how much hints needed. P Hamilton’s puzzle graph Sudoku or partially complete LS Hi 5s. relationship to K_4 and logo. Min cut set/max flow Planarity – draw graphs with min number of edge crossings. Isomorphic graphs Chair on grid move 1. Chessboard with 1 square removed and 2-tiles, 3-tile? Longit, elbow. Labelled bridges: can you do Bridge of K? why not? Put in one bridge, matter where start? 2 bridges to get a HC. MWST, road sealing. Shortest paths Max number of edges and not connected. Location centre for firetruck etc, unweighted, weighted. Steiner tree Number of paths across chessboard. Graphs, degree of nodes, weighted, paths, cycles, Tower of Hanoi: some kids like. Bring it for problem room. Ian S. Ian R will bring. Poster/cardboard how many to do 20, 100 Ian S prepare. Dvd about secret messages. A message to decipher. Pre and post activities Qs. Which has the largest area/perimeter: A 1x1 square or a circle with diameter 1? To the nearest 10%, how much smaller is the smaller area? Similar for sphere. Multiple choice? What’s the 10th smallest prime? How many factors has 101, 60, 2^10? Which number less than 40 has the most distinct factors. What is 1st 5th 20th 100th positive even integer with exactly two threes as digits?
 * Problems room**
 * Colour room** : C Schur, 2 colours (provide poker chips and a number table). Can you beat 7? If can then try 3 colours. How high can you go? (at least 14) . 3-colour a graph, vertex, edge. Ramsey numbers R(2,3) and R(3,3) as colouring.
 * Outdoor room measuring tapes,**
 * Robot room** John B to prepare. Extension : revs from RR to AS. Number of revolutions of tyre from RR to AS, say 80km. What’s needed to be known? How to estimate? Nearest answer is prize. John need know bus tyre size and estimate c.f. robot.
 * Thinking/Learning room**
 * Quiz (allow local explan time for some Qs)**

POSTER 1-100 write up a way of getting n using each of 1989 once each and any operations. Q Is cube root allowed? No. Roger/Ian re 1989 Jeanette

Reference: Holton’s book and more ideas. Ian R

**Problem skeleton** Most problems presented as optimisation problems involving constraints. //Constraint: set of rules or restrictions that must be obeyed.// Caroline, Leah will do the skeleton – production issues. e.g. from Colour Room Statement of problem: Breaking The rules. How far can you go? 1a You have 2 colours (of your choice). You are to colour each of the numbers 1,2,3,4, … with a colour subject to: Constraints (teachers may need to explain constraint). Constraint A: If b and c are the same colour then b + c is a different colour. Constraint B: The numbers b and 2b have to be different colours. Problem: 1a Assuming Constraints A and B: What’s the largest number (call it n) that you can colour in this way, given that you have to begin with colouring the number 1 and colouring each consecutive number up to and including n? 1b What answer do you get if Constraint B is not used? i.e. only constraint A is imposed.  Is that the answer???? WE DON’T TELL THEM. They can choose to look in an envelope. 2. You are now allowed 3 colours: 2a What answer do you get under constraints A and B? 2b Can you colour 1, …, 18 with constraint A only? Can you go further? Resources: Poker chips and a strip or other way of showing the first n integers (n <= 20). How do you know that you can’t do better. Notes: short explanation how to approach such problems. Problem: Given the graph … and 3 colours, can you colour the graph so that Constraint A: Adjacent vertices are not the same colour Or Constraint B: Incident edges are not the same colour Or Constraint C: adjacent areas are not the same colour. Use 4 colours? Translate this to vertices are areas? Give historic account of 4 colour theorem? What if the world is a donut??? Or use this last one for drawing for edge crossing minimisation? Given K_5 can you colour it so that no blue or red triangle? What about K_6? Each room: demonstrate the ideas in some form initially. How? Kids get: Workbook (with all activities?). They complete as wish and we collect and mark on sat night. Ian R. Each kid, pen 4-colour, paper, plasticine multi colours, string, spiral bound. Ziplock bags (strong enough?) What about shopping bags – donation from a shop. Who could organise? stick on labels for kids to write own name. John B

Hi all, I'm a bit busy catching up but we have lots of decisions made last Saturday. Thanks to everyone. I hope to update all of this by COB wednesday but with some updated later today. Please consider the following 2 drafts: logo, activites pro forma: with the logo to replace the blackboard on the pro forma. Please send comments before COB wendesday. We decided on a black T-shirt so the logo will probably be red ochre vertices and writing and yellow ochre edges on the t-shirt. Thanks to Mick K (and OLsh man ??) and Caroline O.
 * Enrichment activites, tasks, planning logo**.

9 May 2009: very basic design - will be looking at possibly no longer than 2 pages (back to back) on coloured card. Will work on the colour world this week with Leah and Val from OLSH before re-submitting to Ian for comment. If it's a go, will then print and laminate the cards for this 'world'. Are other worlds happy with this simple design? Will also have the envelopes (A4) ready for all the worlds with the exclamation/question mark on it so that you can display it in your 'world' - we will come up with a few "!" questions for the colour world in case the students loose interest or find certain tasks too taxing - might be an idea for others worlds too? Each world will also need some extra paper for the "?" envelope. Caroline
