From ATM, see the Summer Solvers series, For Twitter users these are tagged #summersolvers. Each day in August, at 10 am, ATM are posting a problem from their archives for a range of age groups, we have problems to work on for KS2 to KS5 (UK ages 6 – 18).

For August 4th we have Number Spirals, from 30 Years On, a collection of classic mathematical ideas and activities. Note that you can look inside the book and the pdf includes 2 problems, Fractional Triangle and Number Spirals.

• August 4th from Geometric Jolts see this post, Geometric Sparks also Dietmar Kücheman’s blog.
• August 3rd Fault Lines from Points of Departure – I recall using Points of Departure when GCSE coursework first appeared!

…and on the subject of GCSE coursework, there are some classics in this old Edexcel document.

Nrich are again publishing a challenge a day throughout the UK summer break. Every weekday from 10 July to 1 September, a new challenge will appear on this Primary page (for under 11s) and this Secondary page (for over 11s). Once students have tried the day’s challenge, they will be able to compare their approach to previously published students’ solutions.

Also, from Nrich, remember there are many interactive games and puzzles.

Perhaps try some curve stitching on Transum. Also, on Transum, you will find School Holiday Maths Activities; this collection has many activities to encourage students to continue their learning during the holidays. These are categorised, and we have a lovely mixture of learning, puzzles, and games to make students think. There is a great deal of choice here. See also the full list of all fun maths activities.

Try these brilliant GeoGebra puzzles from Daniel Mentrard, also his 64 geometric puzzles.

Perhaps try Tangram on Mathigon.
How many of the different shapes can you make?

Nrich also have a Tangram activity for students age 7 – 11 or for 5-14 years olds try Tangram Pictures.

I do enjoy puzzles, and the summer break offers time for more! Try the series of pages, Puzzles & Games available from the top menu.

To highlight just a few resources from 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.

From the excellent Number collection, a game from mathFROG allows students to practice order of operations against the clock.

On Geometry of course follow Catriona Agg who regularly posts new puzzles and has made her collection of screenshots (Google Drive link) freely available.

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

On Probability and Statistics try…

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.

---

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, a complete solution, and printable/supporting materials.

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.

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 Back to School collection of activities from Transum Mathematics was a reminder of many activities I like and a source of some new discoveries. Looking at the Develop Your Memory suggestions, I noted Number Recall something which I think I’ll try with Year 7 when we look at Statistics. It is often said that the average person can remember 7 digit numbers; the Transum activity allows a choice of the number of digits so we’ll see how good our memories are! I rather like the Kim’s Game activity here too which led me to a collection of Kim’s Games on Transum including Angle Theorem Kim’s Game, something to try perhaps when reviewing Circle Theorems.

In fact, Transum has a whole collection of memory activities, the collection includes the various Kim’s game activities and many more. There are several pairs games, note Venn Diagram Pairs, which offers a choice of five activities including the traditional pairs game. We could also try the Formulae to Remember activities.

On the subject of pairs games, you can also find some on Nrich, try Shapely Pairs for example, where students turn over two cards and can keep the cards if they can draw a triangle with both properties. Quadrilateral cards are also available and there are further questions to think about. Or try a game of Statement Snap, where you will need to know about number properties.

We have more choices of math memory games – Mathisfun has a collection too, a useful index is provided of HTML5 Math and Logic games.

You might want to make your own Pairs game, I think some A level ones could be useful!
