Just after breakfast this morning I tweeted the following:

And very quickly I got the following replies:

1. goze01@stujohnson I have answer. Not telling yet. Get him to list the combinations of numbers when multiplied give a 0 in unit column. :-)19 minutes ago from Echofon in reply to stujohnson
   
2. Steepholm@stujohnson I assume there's also some way of doing it mathematically that a 9-year-old could figure out.about 1 hour ago from TweetDeck in reply to stujohnson
   
3. Steepholm@stujohnson I've just written a little program to do it by brute force - 32 * 3125 is the only solution.about 1 hour ago from TweetDeck in reply to stujohnson
   
4. traceymadden@stujohnson Suspect just being asked to find all the factors of 100,000 and identify the ones that match the criteria.about 1 hour ago from TweetDeck in reply to stujohnson
   
5. traceymadden@stujohnson Try looking 4 clues on how they are 'supposed' 2 solve this in their maths workbook (should lead on from last lesson).about 1 hour ago from TweetDeck in reply to stujohnson
   
6. pk_kent@stujohnson 32 x 3125. Do factor analysis of 100,000 - divide by 2, again by 2 etc. u end up with 2x2x2x2x2x3125about 2 hours ago from Echofon in reply to stujohnson
   
7. katiepiatt@stujohnson got to be 3125 x 32, I divided down 10000 by 2 until I reached a number that didn't end in 0, then found the other factorabout 2 hours ago from TweetDeck in reply to stujohnson

So my son worked it out by:

• dividing 100,000 by 2 until he got to a number that didn't end in 0 (3,125)
• then dividing 100,000 by 3,125 which gave an answer that also didn't end in 0 - 32
• Bob's your uncle!

So thank you to @goze01, @steepholm, @traceymadden, @pk_kent and @katiepiatt!!

A new tutorial on being a critical student

Steve and I have just produced a simple tutorial to try and explain/demystify what it means to be a critical student.

The tutorial is created using a simple PowerPoint slide show which is then recorded and audio added using screenr.com. Screenr is exceptionally easy to use - especially when you discover the pause button. The 5 minute limit is a useful discipline. Files can then be uploaded to screenr or YouTube or downloaded as MP4. It's brilliant.

I had some really useful comments back via Twitter (most of them within 30 minutes)  - which are listed below. If you have any comments then please let me know. This is our first experiment of doing tutorials using PowerPoint plus screenr and I think given our first experience, we'll be doing more soon.

How to tag anna

I wrote a few weeks ago about our tagginganna project. Well, it's moving along nicely (slowly but nicely). I mentioned that we were either going to use Diigo or digress.it. If you're interested you can join our Diigo tagginganna group and then comment on our copy of Anton Chekhov.s Ward No. 6. We'd also like you to comment using digress.it which you can do at http://stujohnson.digress.it/

And if you need a bit of guidance...

Diigo

This is how you comment to our tagginganna group in Diigo

digress.it

This is how you comment via digress.it

Over to you!
