Marcus du Sautoy’s, Maths in the city site includes a suggested tour of London which looks at networks, geometry, resonance, curves and topology through the medium of chalk, sweeties, slinkies and rope!
The London tour includes St Paul’s Cathedral, John Shortt has written a Maths trail for Saint Paul’s, the ideas from which could also be used for other buildings.
So – just a few days to go. I have a couple of Year 12 (UK age 16-17) lessons left. We have done everything we should and made a very good start to the Year 13 course – so what to do for the very last lesson? These logic puzzles from John Prattshould keep us happily and usefully occupied. (I have added these to the Puzzles page on Mathematics Games.) Or we could try another Kakuro Puzzle, studentswere fascinated by these when introduced to the puzzles by a member of the class. At the end of the year we ask Year 12 students to do a presentation to their peers which works well.
Still thinking about games, I see that in the latest Nrich newsletter, Strategy games are featured for Primary teachers; these would also be useful for lower secondary.
This week I was pleased to see the new podcast from TES, ‘The Big Conference Interview Special’ which features interviews with some of the speakers from the TSM conference and includes the pros and cons of using iPads in the classroom, a new curriculum for post 16s and an in-depth discussion about what the new UK mathematics curriculum will look like. At about 16.5 minutes in you can catch Criag Barton talking to me about the use of technology in the Mathematics classroom. The links I refer to can all be found in the slides here.
The school year is coming to an end for teachers in the UK and looking at the statistics for recent popular posts I can see people have been searching for end of term activities. I have recently updated this post with suggestions for such activities. Recent additions include fun with some plots on WolframAlpha; there are in fact a whole family of Star Wars curves!See also many other fun curves!
If those WolframAlpha equations are a bit much for younger students they could try something simpler using the Desmos graphing calculator; look at Alec Schultz’s PacMan for example, you could just show your students how to restrict the domain for straight lines, maybe show them the equation of a circle and see what they can produce! For more Desmos art have a look at this wonderful collection! (I have added a post to Mathematics for Students to show how to display parts of lines and circles on Demos)
Wishing teachers everywhere a happy holiday(only WolframAlpha would give you the Scrabble score as well as the definition!). For teachers already on holiday I hope you are having a great one.
National Strategies – Exemplification Examples: Geometry and Measures
I have always found the above task, suggested in the National Strategies exemplification examples (click on the above image for the pdf) an excellent one when looking at types of triangles and their properties. Students are required to find the number of unique triangles on a 3×3 grid. The task can be extended by asking students how many unique triangles there are on a 4×4 grid. A good discussion can be had on being systematic in approach.
The next time I teach it I will certainly use a Geoboard.
