I do enjoy puzzles and the summer break offers time for more! A job for the holidays is checking and updating links to such resources. I have now incorporated a series of pages, **Puzzles & Games** on this blog, available from the top menu. All resources have been checked and there are many new additions in all categories. Further additions will be added over the next week or two.

To highlight just a few of this large collection, **Algebra** includes the lovely SolveMe mobiles puzzles.

Or for a rather different approach, try **Shuttle Mission Workshop** from Math Playground, here students build and solve their own visual math puzzles. Play **Shuttle Mission Pro** first to practise.

Nrich features on many pages including reading; Nrich has many excellent articles on the use of games in the classroom; hence a **Reading** page.

On **Number**, Math Playground, **PEMDAS Exhibit** provides great practice for order of operations. Touch an operation to form that part of the operation.

On **Geometry** of course follow **Catriona Agg** who regularly posts new puzzles and has made her **collection of screenshots** freely available.

Following each puzzle, you can find a discussion on the puzzle. Have a look at **this puzzle** and discussion for example.

In response to this puzzle, you can see various solutions including an **Autograph file** created by **Rob Smith**. Rob has this up to change both squares and you can move also move a point on the smaller square.

Another brilliant Geometry puzzle author is **Ed Southall** who has made **40 puzzles** available to celebrate his 40th birthday; he has also provided **slides for teachers**. Check his **Geometry Cheat Sheet**.

A new category is **Probability and Statistics** games…

The collection includes from Cambridge PhD student, Omar Wagih ‘**Guess the Correlation**‘, a rather addictive game with a purpose – Omar Wagih is collecting the data on the guesses collected and using it to analyse how we perceive correlations in scatter plots. Select About to read the rules and further details.

Another new category – **Underground Maths**, the page includes several resources on puzzles and games from Underground Maths

From Underground Maths try **Equation Sudoku** for example.

We can write down equations:

c+g+k=17

f+g+a =19

m+k+c =16

and so on.

As always on Underground Maths we have suggestions and a complete solution as well as printable/supporting materials.
