Probability is one of those topics where it's best to "see it".
As a serial organiser, a brain cell explodes when I read on a social network involving teachers, "where can I find?" or "has anyone got?".
A resource I put together for practising rounding using significant figures.
Here's a self-checking, simple questions, as you get the answers correct the tree lights up.
Nothing fancy. Just needed something for a computer lab tomorrow.
One of the challenges I had this week when students were constructing rectangles and squares using a ruler and set square (drafting triangle) was checking the accuracy of the measurements (sides and angles). I walked around with a ruler and set square checking their drawings.
I found this design on a photocopied worksheet from an old textbook, but I don't know which, so cannot credit.

For my HSC Mathematics General 1 class, we are currently completing the Focus Study FSPe1CEC Water usage and collection.
In this topic, students interpret information, make comparisons, and perform a range of calculations in relation to personal water usage.
These are resources I developed for a Year 9 5.1* class.
(What is not shown in these resources is not all of the conceptual steps I took with this class.)
If we can determine the altitude of a plane in front of the moon, why not try the altitude of the Space Shuttle Atlantis in front of the Sun?
Here’s a second foldable for the Preliminary (Year 11) General Mathematics course for the topic DS1 Statistics and society, data collection and sampling.
This second foldable is about classifying data.
I’m trying to make the time to create foldables to use with my Year 11 General Mathematics class. The topic DS1 Statistics and society, data collection and sampling lends itself to foldables.
The first foldable is for the process of statistical inquiry:
posing questions, collecting data, organising data, summarising and displaying data, analysing data and drawing conclusions, and writing a report
TeachMeet AC Maths on Thursday gone was fantastic. Check out the wiki page for the presentations.
Here’s my 2 minute presentation about MathsLinks.
Lots of links added to MathsLinks and and files added to MathsFaculty.
For teachers in Sydney, I hope to see you at the TeachMeet for the Australian Curriculum in Maths – this week, Thursday 1st August 2013.
A reminder about the new feature added this week. You can now leave a comment on any link or resources shared on MathsLinks and MathsFaculty.
The comment might be a teaching idea or a review of the resource.
In January, I wrote “let’s make 2013 the Year of Sharing”. We probably all know that some of the best sharing is not a specific link or a tangible resource, but an idea. Those discussions may happen in the staffroom, over a coffee, on playground duty or on a social network.
Sydney, Australia, based teachers put Thursday 1st August 2013 in your diary for the TeachMeet Australian Curriculum Maths.
This week, MathsLinks hit 700 links all categorised by topics and syllabus.
For a few years, I’ve noticed that kids not only don’t know/struggle with their times tables, but also general ‘number sense’.
Mathematical Induction, topic 7.4 in the NSW Board of Studies Mathematics Extension 1 Syllabus, is difficult conceptual. I suspect students think there is a bit of smoke and mirrors happening. One introduction that I use, I first saw in a resource by Stuart Palmer. The same story appears in this article online: Mathematical Induction (PDF 92KB), Helen Bush, Reflections August 1992 sourced on NSW HSC Online.
For users of Pinterest, you can now share links on MathsLinks to Pinterest. Click the Share dropdown.
Try it on this link, you get a nice screenshot of the site in Pinterest.
Try out the Word Search on MathsStarters. There are only three versions at the moment (although the placement of the letters is different each time you play the game). If you’d like to add a game, just send me a comma-separated list of words and a title for you game. For teachers in NSW, Australia, my current aim is to make a word search for each topic in the NSW General Mathematics syllabus.
Also, I’ve added the search functionality back on this blog.
Now that we have a National Curriculum in Australia, let’s make 2013 the Year of Sharing.
Some seasonal links this week, enjoy the break. Merry Christmas.
Keep an eye out for new look sites soon.
This is part 2 of my electronic worksheets for Consumer Arithmetic. Part 2 focuses on Spending Money, in particular: profit and loss, discounts, purchasing, best buys and buying on terms (hire purchase). (Part 1 focused on earning money)
Since May, I have been posting a weekly summary of the links and resources added to my other sites, MathsLinks and MathsFaculty, calling it “MathsClass This Week”. A quick poll: (viewing via an RSS feed or email, you probably need to visit the site to complete the poll)
A lot of links and files this week…
Did you go to the 2012 MANSW Conference? If you don’t have a blog, consider leaving your reflections as a comment here.
A foldable for reviewing the Rules of Differentiation. Click the preview to see the full version.
Year 11 Mathematics have one of their three periods a week, last period on Fridays. Of course, they’re not highly motivated at that time.
The other week, we folded parabolas, I called it “Arts and Craft Friday”.
The next week, they surprised me by asking what we were doing for “Arts and Craft Friday”... I had nothing!
I suspect that as you find great resources on the net, many time, like me, you still have a need to scaffold an activity around that resource… maybe resulting in the creation of supplementary material.
Most teachers have a USB stick full of their teaching resources… similarly most schools have a file server with a Mathematics folder chocked full of stuff that has been randomly downloaded, scanned or created.
But, what about web-sites? I’ve seen many Word docs named “websites.doc” and shake my head. At a professional development course I went to, the presenter had addresses for web-sites he used in a text file, I suggested he use MathsLinks, but his reasoning was sound – he had the links with him with other resources for a lesson. Social bookmarking sites like Pinboard (my recommendation, here are my maths bookmarks) are great, but I found categorising on MathsLinks suited me even better, then I made it public.
Now I’m adding some features to MathsLinks which are a little bit old-school, but will hopefully make it more useful when programming and sharing links with colleagues:
Save link to your computer – this will download a “url” file to your computer, a shortcut to the web-site. Double click it on your machine and you will be taken to the site. (Mac users, it will open Safari, no option)
Print to PDF – downloads a PDF with the essentials about the web-site with links to the site on MathsLinks as well as direct to the site.
Try it on these links…
Nothing to do with MathsClass, this week saw the addition of Emma to our family.
Four maths teachers kindly shared their work on MathsFaculty for others to use.
Recently my online focus has shifted to my network of sites. This network is about making the essentials for maths teaching easier to find and more accessible.
MathsKit is a page of all those everyday resources.
MathsLinks now has over 500 online activites for maths, all categorised.
My new site, MathsFaculty is for maths teachers to share. I suspect that everyday, teachers waste time searching for, and if they don’t find, creating resources. Let’s fix that by sharing.
Each week, I’m going to use this blog to summarise what has been added across these sites.
* “This Week” is more like “recently” for this first review.
