These three interactives from Shodor are a good introduction to Venn diagrams:
Venn Diagrams, Shape Sorter and Triple Venn Diagram Shape Sorter
With the Triple Venn Diagram Shape Sorter you can either set the rules or guess the rules by selecting the appropriate botton:
I was asked recently about my own top ten Mathematics websites, this request and remembering Edna Sackson’s comments on her ’10 Ways…’ series reminded me of the various ‘Top (insert number here) Mathematics Websites’ posts I have read; all of them have left me with the thought that so many excellent sites are missing from such lists. Really such posts (including this one) should be titled ‘My Top 10….’ as they understandably include the author’s favourites. For my own list I have decided to include some categories as well as individual sites which gives me the excuse to mention far more than 10! Note that every site mentioned here is free to use.
So in no particular order:

Two excellent watery demonstrations this week!
A resource I use regularly to demonstrate ‘real life graphs’ comes from the excellent CLEO Resources (Cumbria and Lancashire Education Online).
Fill the various flasks with water and investigate how the height of the water varies with time.
From the Connected Maths Project (Michigan State University) comes this very clear demonstration for exploring the relationships between the volume of various geometric shapes.
Fill a shape with water then drag it to another shape to empty the water into that shape!
(Other activities I particularly like on this site include tessellations and the isometric drawing tool from the 6th grade resources, Virtual Box from the 7th Grade resources and the Painted Cubes investigation from the 8th Grade resources.)
Do you ever need a way of choosing a random student or perhaps a timer to display on the IWB? There are various free resources available to help!
This random name selector by John Mclear will randomly select a name from a list you can easily input. (I keep readily available files of student names to just copy and paste). Once a name is chosen you have an option to start a two minute or seven minute timer. It is possible to remove a name from the list once it has been chosen.
It struck me recently that so many blogs are addressed to the teachers, so perhaps it’s time to provide one for the students!
Hence the new Mathematics for Students a companion blog to this one but addressed to students.
Any thoughts / ideas / comments – please let me know.
