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.
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 
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.
