I am pleased to announce Bar Math, a complete system
designed to help students visually understand Math concepts. Ideal for teaching arithmetic by visually demonstrating
the four rules addition,subtraction, multiplication and division. The same system can be extended to
provide a better way to learn about fractions, directed numbers and algebra.

Lesson starters can be a great way to get your students minds working and focused.
They can also allow the teacher a few minutes to get organized for class while the students complete the task

Sorry it has been a while since there have been any improvements on the
site. This is partly as I just haven't had much time to do so. But also
I have been developing a new exciting system called bar mathematics that I hope
will aid with teaching and learning Mathematics. I will be talking about this
is another blog post.

The latest activity on Visnos, a reimagined version of the Sieve of Erastosphenes.
Although there are other versions of the sieve on web, most are just a
rehash of the standard method used by school students across the globe.

Fractions, decimals and percentages are an important part of the
mathematicians toolkit. Especially being able to quickly convert
between each type. This new activity helps anyone learn about the
process, by using a either a brightly colored square or circle that can
be divided up into different colored parts.

So just to point out that PI day has once again come around. Last year got quite an increase in traffic to visnos as people
visited for the PI interactive activity.
This I am sure was in part helped by the fact that I had commented on every single PI related blog post I could find.

So a lot of changes have been made to the times tables interface, hopefully it is still quite clear
how to use the activity. Icons are now being used instead of plain text buttons, this has two advantages. First they are more compact
and second they work better for none English speakers.

So it has been a while since something completely new was released. The emphasis has been an
emphasis on improving the existing activities. But live today is the new time calculations
activity that uses two independent clocks. The activity can also generate some typical time duration question.

The addition and
subtraction facts interactive activity has been greatly improved. A
tutorial video has finally been added and the interface has been
redesigned with many new features. The automatic mode has been removed,in its place
is a new a new random action button. When clicked a random
number fact problem is created, the clouds of fog or sea transparency
hide the penguins. This allow the teacher to reveal various parts and
so the pupils can deduce what the sum or subtraction is.

There are lots of different ways to show that the exterior angles of a polygon add up
to 360°. This one uses the polygon explorer and was found quite by accident
while testing the activity on an iPad. The short video shows how to do it.

Finally the latest shiniest version of the website is live, this
includes the blog section which you are now reading. Many more updates
listed below, the biggest change though is now the activities will work
offline.
