I do enjoy puzzles and the Christmas break offers time for more! During the Summer of 2021, I incorporated a series of pages, **Puzzles & Games** on this blog, available from the top menu. Since then new additions can be found in all categories; you can see from the index that you can try puzzles and games by category as well as access collections.

To highlight just a few of this large collection…

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 **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.

Here’s a recent puzzle you can see with many replies:

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

The **collections** page includes sites many sites featuring numerous resources.

For example for some very attractively presented Puzzles and Games – try **Mathigon**.

In the category **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.

**Algebra** includes the lovely **SolveMe mobiles puzzles**.

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

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

The **Underground Maths** page includes several resources on puzzles and games.

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.
