A few updates ….

Top Posts and pages is proving popular – this is updated regularly. 

Mathematics for Students has had several updates recently, a series of Explore pages direct students to resources for exploring a topic.

The Notes and Videos pages have both been updated, check Just Math Tutorials for example. The Useful Links page has been updated several times, including a new page directing students to commonly required constructions on Math Open Reference.

Mathematics Calculators and Tools has several online calculators.

Mathematics Games has a collection of favourite games – many from Nrich. Several games to help students practise tables have been added recently.

There are many resources for starting and ending lessons described on Mathematics – Starters and Plenaries.

Plans and Elevations – Wisweb Applets

Update – a new environment for the Wisweb Applets – these work beautifully in modern browsers.

This week I need some resources to demonstrate plans and elevations. There are several Wisweb applets from the Freudenthal Institute which are excellent for this topic. These work well on  the interactive whiteboard for demonstrating to students, they are also ideal for students to explore themselvesJust in case you  get a Java error message even though you have an up to date version of Java installed then you need to Configure Java (see your programs list) and under the Security tab add an exception site: site address here. I left my security setting as high and this did solve the problem.

Cube houses shows several models with their elevations, select drawing then 3d-model to give a model you can rotate  to generate different views.

Readers familiar with the excellent Improving Learning in Mathematics materials may recognise the applets for building houses; these are described in SS6 – Representing 3D shapes which has suggested lesson activities and describes the applets (see pages 4 and 5).

Building Houses allows you to create buildings and see the plan, front and side elevations as you build. (If that link does not work – try this).
You can add (build) or remove (break down) bricks and control the size of the square base.

Building houses with side views challenges students to construct 3D models given the plans and elevations; the task is made more challenging by specifying that as few cubes as possible should be used.

Note that in order to achieve the minimum number of cubes, ‘floating’ cubes are needed.

Note that these resources have been added to the ‘explore‘ series of pages on the companion blog for students.
Update – these resources worked well with my students – they particularly enjoyed the challenge of trying to build models using the minimum number of cubes!

Readers interested in the Improving Learning in Mathematics materials further may find IWB Resources  useful as it has a flipchart and notebook file for each of the activities. This site is a result of the NCETM research project: Enabling enhanced mathematics teaching with some interactive whiteboards (September 2006- September 2008) and is supported by the IWB research team at Keele University and the www.iwbmaths.co.uk team.

Numbers in love with themsleves!

Watch the video from Numberphile to learn why 153 is in love with itself!

Numberphile launched their first video appropriately on 11th November 2011.

The Numberphile site which has a series of videos from Brady Haran has been added to the Videos collection in this Evernote notebook.

Another recent addition to this collection is PatrickJMT’s – Just Maths Tutorials – an extensive collection for students.

Note that there are suggested collections of videos to direct students to on the videos page of Mathematics For Students.

Happy 2012!

Happy 2012! The above image is from Jesse Vig’s geoGreeting site where you can enter a message and obtain a link which you could send in an email. It is also possible to send as an E-card. Jesse Vig noticed whilst working on a Google Maps project that a number of buildings looked like letters of the alphabet when viewed from above. and his website was born!
A rather novel way to obtain images of numbers!

So to complete the new year greeting we need of course some number properties of 2012.
We can turn to the Mathematical Association’s number a day blog. (Click on the image for the full post).

Or we could use Tanya Khovanova’s site: Number Gossip where we learn that 2012 is evil!

WolframAlpha can of course supply some number properties of 2012 or provide a calendar for the year …or even send us best wishes for the new year! Wishing everyone a great 2012!
