A consistently popular post on this blog is ‘Lovely Puzzles‘ which has links to many puzzle sites which include mathematical puzzles. This seems a good time of year to investigate some of these further. A good puzzle for Christmas Eve perhaps (or any day!) would be ‘Make 24’.
Can you make 24? You must use all the numbers once and you are allowed the four operations and brackets.
(Further information and solutions for Make 24 and other Number puzzles are listed on the Number page on Mathematics Games). Number puzzles like this can make excellent starters.
Whilst many teachers use Suduko and Kenken type puzzles (note that teachers can sign up to receive free weekly KenKen puzzles), perhaps less familiar is Rogowhich is very easy to learn.
This post has taken some considerable time to write as I have been very happily distracted by all these lovely puzzles – including joining the dots (from Conceptis Puzzles) something I used to love doing as a child!
It’s been a busy weekend marking mock examination papers!
So this week I thought I would simply highlight some resources I have mentioned on my other blogs and mention a couple of recent discoveries.
Have you tried Rogo?This easy to learn puzzle could make a good starter / settler activity.
On the Starters blog I have included Jonathan Hall’s excellent Flash Maths site. Jonathan links to the most popular starters here.
On Mathematics for Students I recently linked to some Polar Coordinates resources at the request of my Year 13 Further Mathematics students.
Because just a few minutes spent on Twitter can be very productive. Take this tweet from Craig Barton on an excellent resource – perfect for my Year 11 students revising for their GCSE module in the summer.
Being very selective in who you follow allows you to connect with teachers and other educators beyond your own institution.
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.
