Well done to Fin W and Evie from Mounts together with Freddie and Alex from Moneybury, who won their heat of the Hertfordshire Year 5 Maths Challenge against a range of schools from across the Hemel and Rickmansworth areas.

We hope that they will now go forward to represent the school in the County finals in June.

Also well done to Skye who took part in a Judo competition at the weekend and was awarded a bronze medal, even though she was taking on opponents more than one and a half times her own weight.

Cameron managed to win an informal coin tossing prediction competition in Mounts today, not once but twice. To do this, he correctly predicted the toss of a coin on at least twelve occasions in a row. Does anyone know how likely or unlikely this feat is?



Decimal Darts

The Mounts Maths set have been playing Decimal Darts in our Maths lessons this week. In case anyone wants to do some extra training, here is a link to the game:

Here is a link to the Rope Tug game:

One player versions of both games are available.


For those people who like Maths puzzles, have you tried Kakuro yet?

Kakuro is like a crossword puzzle with numbers. Each “word” must add up to the number provided in the clue above it or to the left. Words can only use the numbers 1 through 9, and a given number can only be used once in a word. Every Kakuro puzzle has one and only solution, and can be solved through logic alone.

There are some online puzzles to try at

We suggest you try the easy level. You can check your progress at every stage by pressing the check button (if they come up red, those are the mistakes)

Maths Challenge

Well done to everyone who took part in the Maths Challenge at Ashlyns this afternoon. Although none of our teams won, a lot of mathematical thinking was undertaken, there was a surprising amount of running around  and a good time was had by all. Well done to the members of the BBs and The Best and Furious who were among our highest points scorers today.
