Thanks for those Jonny

Hi studymaths;

I respect that you thought of someone else when you had free time.

Hi;

I get to level 10 fairly easy after that my mouse skills degrade rapidly.

Got to Level 17!

Had to guess a few of the big ones on the last 3 levels and got lucky.

I quickly eliminated digit-sums that are multiples of 3 for the larger numbers that I didn't know, but after that I panicked and let the mouse run wild.

Panicked again.

Thanks, Bobby.

With my second flop on L17 I was annoyed that I didn't get to L18 because I only had one prime to go.

I felt tempted to learn some higher primes so that I could advance to a higher level...but then I'd fail that higher level and be annoyed that I didn't get to the next level.

And on it goes...... Hey, that reminds me of the song "And so it Goes", by Billy Joel. Here's an a cappella version of it by the King's Singers that I really like. Fantastic harmonies, timing and feel.

The idea of me learning larger primes doesn't appeal, so I won't bother with that.  I'll just play using what I know (plus guesses).

Anyway, somebody who's already done that extra learning will get a score that will make mine look puny.

Level 17 is a very good score! My best is 15.  I told my pupils that anything over level 5 shows that they know what their doing when it comes to primes, anything higher is a bonus!

I'm thinking the 5 second penalty for an incorrect prime is a little harsh, possibly might reduce it to 2 seconds.  Or give 20 seconds per level rather than 15.

Anyway thanks to all for trying the game, it is appreciated.  Now if only my pupils they could remember what square numbers, triangle numbers, factors, multiples etc.. are

Hi,

They get to about level 4 or 5 then run out of time.  This for me shows understanding of primes, even if they can't identify the larger ones by memory.

What is fun though is using an interactive whiteboard and then get pairs of pupils up to the front to work as a team.  With double the hands they finish levels in half the time   Although this can cause arguments between them if one of them clicks a non prime number!  They have reached level 10 doing it this way.

Indeed, in fact I did try it with more than two pupils at the board but then the adage "too many cooks spoil the broth" applies!

Yes...youth has its advantages. I won't be 27 forever , but maybe when I'm old I'll have learnt enough larger primes to be able to blitz my best score from my youth. That is, if hand shake hasn't set in by then.

I bettered my previous score but clicked on a multiple of 2 on the last level! That killed it, as I only had a few seconds left. But I was gone anyway, as I still had 4 primes to go.

Hi studymaths,

A smaller time penalty for incorrect answers, particularly on levels with 3-digit (and greater!) primes, would be good. That would allow for some quick mental arithmetic with at least the first few primes to see if they'll divide into the test number. I did that a small number of times on my way to L20, using primes < 23.

I was able to use that tactic as I'd worked my way through the lower levels as quickly as I could and had a time of about 55 seconds with 3 or 4 levels to go.

Hi Bobby, yeah I use the games at mathopolis with my pupils as well as the games as mathisfun.com, boxup is one of my personal favourites.
From a pupil point of view I find that any game which has a timed element are the most popular with kids.

Thanks to everyone who tested the prime game as a result of the feedback I've changed the rules slightly.  You now get 20 seconds per level and only a 3 second penalty for an 'incorrect prime'.

Level 25 should be achievable now

That would be impressive. Each at the start of a level each tile is assigned a number between 1 and (10+level*level).  So at level 50 all the primes up to 2510 would have to be memorised!

I think I'd have to make the tiles wider as well
