## The Fallen: Lest We Forget.

Thanks to @FarrowMr for showing me this poignant video about D-Day. Two artists Andy Moss and Jamie Wardley set about making a tribute to the 9000 soldiers that fell during the D-day landings. More can be read here: http://thefallen9000.info/

The video below shows some great pictures of the soldiers etched in the sand:

Maths links could be:

Estimation - Stop the video at any time and estimate how many soldiers you can see?

Time - If each etching took 5 minutes, how long in total was needed to do 9000?

If there were 200 volunteers how long would it take them?

How about 500 volunteers?

Due to the tide if you only had a 12 hour gap to create how long would you have to create each etching

Measuring - If each soldier measured 1.5 metres, how much beach would be needed to create the tribute?

Shape, can you see any symmetry or symmetrical patterns with the etchings?

## A Fast Maths Trick for Mental Subtraction ?

I was talking to Rob, of the Literacy Shed on twitter as he was showing me another way in which children can subtract

large numbers without carrying. I said I had a video of it, but unfortunately it is not the same, but is still very interesting. Has anybody taught their children using this method, if so can you let us know how you got on. Contact me grahamandre@tiscali.co.uk or on Twitter @grahamandre

## 100 Million in 100 Seconds.

This number at the number 100,000,000 and how big it really is by answering some questions. you may want to ask your children / students to try and guess the answers to them first before showing the video.

The questions are:

How long would it take to count to 100,000,000 ? If you went back in time 100,000,000 minutes, what year would you go back to? How many Olympic size swimming pools would 100,000,000 cups of coffee fill and how many days would it take to drink them? How many skyscrapers the size of the Empire State Building would be built with 100,000,000 bricks? How far would a staircase with 100,000,000 steps take you? How far would 100,000,000 cupcakes laid next to each other reach round the world (starting from London)?

## The Time You Have - In Jellybeans.

you may have seen this but if not please take a look. It is quite a poignant video that takes the average number of days that each person lives and shows these as jellybeans. The beans are taken away to show how long we spend doing everyday things and how many beans we have left at the end. What would you do?

It asks at the end what would you do if you just had 1 jellybean (day) left to live. A good look at number but also good for thinking skills, it would be interesting to hear what answers your children would come up with to the one jellybean question.
