A new year resolution – more frequent posts.

I can make use of The DailyPost, and the community of other bloggers with similiar goals, to help me along the way.

So to 2011 – I feel an easy post coming here! Tanya Khovanova’s Number Gossip site caused interest when I blogged about it earlier. Using it to generate a few facts about 2011, we see that 2011 is deficient, odd,odious, prime and square-free! These terms are all explained on the Number Gossip site.

The Mathematical Association of America has a post on 2011 on its NumberADay blog.


A variety of excellent classroom resources are available from Triptico. They work very well on the Interactive Whiteboard.

Triptico resources are accessed from a desktop application, free to download, so an Internet connection is not required to use the resources.

Try Find 10, perhaps as a starter. This allows you to show 15 statements, 5 of which are incorrect, students have to find the 10 correct statements.
Activities can be saved for subsequent use.

This is an application well worth exploring. The resources include timers, a random name selector, team scorers, also an excellent vocabulary activity, Word Magnets.

Once you have downloaded the application scrolling allows you to see all the activities or use the Favourites menu.

Useful Reading

There is much available on the web – high quality and all free.

  • Have you seen the latest edition of Plus from The Millennium Mathematics Project – University of Cambridge and Focus from the Mathematical Association of America?
  • Looked at the puzzles (and solutions!) from St Mark’s?

These and many other links can be found on the Reading page.

To easily view each site view the list as Diigo WebSlides.
(Further details on Diigo webslides available on a Diigo tutorial.) 

Tarsia Puzzles

With the free Formulator Tarsia software from Hermitech Laboratory, (you can download the software and see more information by following the link) it is possible to create Tarsia puzzle types

puzzles of various types. These work well with students of any age. Most of the published resources seem to be for students age 11 to 18 but as it is possible to create puzzles, teachers of younger students could create puzzles suitable for their classes.

Note that as well as downloading the application it is possible to download selections of puzzles from Craig Barton and from Bryan Dye. Craig also has a section of his website devoted to Tarsia – note all the ideas here for using Tarsia in the classroom.

TES Resources host an extensive collection of Tarsia Puzzles.


A favourite site for my post 16 students is now even better. With funding from JISC the mathcentre site has been upgraded and includes extensive resources. Many of my students like the quick reference leaflets which are available on numerous topics. There are also teach yourself booklets, revision booklets, videos and diagnostic tests. Resources are available for staff and students. See this page for a complete list of all the resource types. This is a site well worth exploring and recommending to your students.
