What to do for those last lessons?
You might want something other than a video, though perhaps consider a Numberphile video or I could make an exception for the counting chimps, a video I was introduced to by Alex Bellos at the SSAT conference which he included in his session and shows the astonishing recall of a chimp – compare the human!
From JustMaths a great end of year pub quiz. I do like the way this ends with a round of Matchstick puzzles, this will keep our students happily busy! Note the very useful recommendation for Matchstick Puzzles from Dawie van Heerden. Whilst this is currently called Quiz 2017 it will work just as well in 2018.
Bingo always works really well.
A team game? Try Workers of Zen.
(ATM publish books of team games).
I must mention A Little Problem for the Holidays!
Some Mathematical games and puzzles perhaps? There are plenty to choose from. Note that the Jeopardy Games from Math-Play.com are written in HTML5 and work on iPads also.
Always popular with students is the game of Countdown. Exellent programs for both games can be downloaded free from Chris Farmer’s CSF software site. For a new challenge why not try Coundown with Fractions from Nrich or another variation – see this Countdown collection.
On a similar theme try Make 24 a game where four numbers in the range of the natural numbers 1 to 9 are chosen randomly; these must be combined to obtain the result 24 – but you may only use the four basic arithmetical operations and brackets. This online version optionally shows solutions as well as presenting random problems. The program will also show solutions for any given set of four numbers.
Learn the syntax for WolframAlpha, perhaps a chance for students to explore WolframAlpha, using the various slideshows, note the questions on the worksheet. Note the last slideshow on a little fun with WolframAlpha!
Explore the Desmos Graphing Calculator (and note the further reference to Desmos below, use Desmos to create some art work!)
For a main activity a Tarsia puzzle provides an engaging activity. I intend to use one to see how many of the formulae needed for the part of the course which my Year 10 students (age 14-15) will be studying next year are already known.
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! See this post on Graph Art on Mathematics for Students.
To generate some more pretty curves why not try Spirograph?! Students could experiment with these online versions to see the various curves that can be generated.
On the subject of Art, perhaps try some of Clarissa Grandi’s wonderful, fully resourced mathematical Art lessons.
These logic puzzles from John Pratt should keep students happily and usefully occupied. (I have added these to the Puzzles page on Mathematics Games.) Or we could try another Kakuro Puzzle, students were fascinated by these when introduced to the puzzles by a member of the class. At the end of the year we often ask students to do a presentation to their peers which works well.
Try (or write a new) Sporkle Quiz.
Still thinking about games, from Nrich these Strategy games are for Primary teachers; but could also be useful for lower secondary.
We could finish with a song or two!
