Just added to MathsStarters: Number of the Day (junior) is for Stage 2/3 students (Years 3 to 6) covering:
represent numbers of up to four digits using objects, words, numerals and digital displays
identify the number before and after a given two-, three- or four-digit number
count forwards and backwards by tens and hundreds on and off the decade
arrange numbers of up to four digits in ascending and descending order
use place value to partition numbers of up to four digits
round numbers to the nearest ten, hundred or thousand

Probability is one of those topics where it's best to "see it".
This screencast follows on from the previous Mathematical Symbols in Word for Mac.
In this screencast, I show a fast method for typing mathematical expressions involving basic symbols (like × and ÷). This method doesn't require the mouse to navigate a menu nor does it require an Equation to be inserted.
This is an update to the second most popular item on this blog, Maths symbols in Word (Mac).
Increasingly I am consuming media on my desktop computer rather than my TV when at home.
Numberphile, for example, publishes one or two videos a week that I want to watch. However, I've always found watching in the browser annoying. Two ways to improve the YouTube viewing experience are:
In the past, Maths teaching resources amounted to printed materials (be it a textbook, BLM). If the teacher didn't like what was available to them, they could hand-draw and Gestetner a more appropriate worksheet.
I am presenting twice in September about how I use technology to engage, enhance and extend in my teaching.
I reckon Maths Bingo is a great starter, ender or in-betweener…
On MathsStarters, I have added a Frequency Distribution Table tool. The tool lets you have 3 to 10 scores, you tally as you go and the frequency and total are calculated.
You could use this on a projector/IWB (the buttons for incrementing the tally are sized for an IWB). Or, students could use this to record data on their own laptop as they collect it – paperless!
Playing with the kids’ toys on the weekend, I came across this car and became interested by the relationship between pulling it back and how far it would travel.
Was it a linear relationship or something else?
Looking around, there are lots of activities for collecting and analysing data using small boxes of Smarties. Here is my version.
Last term I had Year 9 review and learn index notation and the index laws through some self-directed activities.
Having made a Tables Spider this other day, I realised that I made myself a template for creating all sorts of “spiders”.
In 2007, I wrote about a resource, a Number Spider, that I used as a lesson starter.
Each year for the Term 3 SDD (Staff Development Day), the four schools (three 7-10 and one 11-12) in the collegiate I work in get together for a combined program.
This is a resource for skills in working with time.
I’ve been trying to increase my use of the laptops with Year 9.
Here’s a quick starter activity for rounding.
In 2009, Year 9 got their DER netbooks and now they are in Year 10. This year’s Year 9 does not have their netbooks yet, and so this gives teachers a little time to get their heads around the inclusion of netbooks into the classroom. This year, I’m teaching a 5.2 pathway Year 10 class (and a Year 9 5.2 class).
I just posted on my personal blog about how I use the web, looking at how the various technologies (RSS) and tools (Google Reader, Delicious, Twitter) fit together.
Reading blogs and networking on Twitter seem an obvious part of being a teacher. Yet when I take in to school a shiny new resource that I’ve received through one of these means, I usually get asked “where did you find this?”. The person behind the question is often thinking that I spend copious hours sitting at home in front of a computer “web surfing” or trying endless combinations of search terms in Google.
Some chocolate discussion starters for looking at bar graphs: a series of chocolate bar graphs.
Despite every Year 9 student having a laptop for a few weeks, the topics we’ve been covering haven’t lent themselves to full laptop lessons. To end the term, though, we’re reviewing graphs.
A lesson for Year 9 students with DER laptops, or anyone really.
I think that each student using a netbook/laptop in your class presents some slightly different issues in Maths.
This is an amusing video to introduce probability… some of my Year 8s found it hilarious.
As I mentioned, the DER roll-out hit my classroom as we were in the midst of Algebra. Due to a tight program and exams shortly, I had to stick with a couple of topics which don’t really allow for “play” on the laptops as much as I would have liked.
A lot of the Algebra taught at the Stage 4 level is technique, and so matching activities work particularly well to practise and review skills.
Here’s a review of some of the ways I’ve found to make matching activities for use on the laptops.
Not really maths related, but handy if you’re looking at a web-site that will be used on a Netbook.
Week 1 is over, and I need to reflect on what happen when I introduced laptops into my classroom.
A Digital Education Revolution (DER) laptop in the hands of all Year 9 students changes everything… or does it?
Year 9 got their DER netbooks just before the end of Term 3. The first week of Term 4 will be the first time they have them in class, so I wanted to start term with some introductory activities, with a Maths focus.
This post is a work in progress, check back for updates.
20 Oct 2009: Go to update
Last year, I posted the Melbourne Storm Number Plane Logo – and today, exactly one year later, purely by coincidence, I’ve made a Brisbane Broncos Number Place activity.
Having found this tip on
elearnr.org Doug Belshaw’s blog about using PowerPoint:
Find graphics that represent things you do frequently in lessons (perhaps from clipart) and always use these when doing a similar activity. For example, a pen writing for when it’s time to start work or two people talking for discussion/group work. These help reinforce good habits and aid classroom management.
I went looking for some nice graphics to use.
This week, Year 9 were looking at finding the perimeter of shapes that include curves (parts of a circle).
Here’s a quirky little activity that uses the DER laptops.
As a PBL school, we have lots of “Student Expectations” at our school for nearly all aspects of an ordinary day (entering the classroom, in the playground, walking through a corridor – we have narrow corridors, formal assembly). In a couple of weeks, there will be another aspect of the “ordinary day” – laptops. So, I’ve drafted some student expectations for the technology committee at my school to discuss.
As part of the last lesson with my Year 9 class in Term 2, I asked them to write me an email expressing their thoughts about getting their own laptop in Term 3.
This article is not a “how-to” but rather some thinking about using GeoGebra (a discussion starter maybe).
For NSW DET teachers, the Curriculum Support web-site has been updated with resources for the DER, i.e. the laptops being rolled out to Year 9 students.
Teacher’s throughout NSW DET schools are starting to receive their DER netbooks.
Google Sketchup is one of the applications bundled on the DER netbooks being rolled out into NSW Public High Schools in Term 3. But as it’s free, you can download it now for Windows XP/Vista & Mac OS X.
From The Australian, Technology lesson one: teach the teachers comes this:
... “This isn’t just about teaching teachers to use the technology,” Professor Stoney said.
“It’s about teaching them to use it for learning. How do students learn with technology?
I recently contributed some comments to the executive at my school about the DET roll-out expected to be happening soon. A slightly editted version is below. I’m really not sure where the executive are at with this roll-out, I haven’t heard much except from the computer coordinator – it’s a shame, or more accurately, it makes me nervous, because there is the potential for a lot of problems to arise from this roll-out if we’re not prepared. I’m republishing my comments because they might help you in engaging with your school about planning and preparation.
My previous post on having an IWB in my classroom was written about three weeks after it’s installation. Tomorrow, we’ve got an IWB consultant/trainer/type-person-thingy coming to school, and I was asked to share what I’ve been doing with the IWB. So I wrote a quick list.
The DER, as it is unfortunately named, is about to hit NSW schools.
With laptops rolling out shortly and projectors appearing in some classrooms, we should be thinking about collecting digital media for use as stimulus or investigation material. So, the other day when filling up my young daughter’s bottles, I took some pictures.
I wanted to play a multiplication bingo type game with a class the other day, so I grabbed two 10 sided dice (apparently you don’t need to call a single dice a “die” anymore) out of the cupboard. Then I thought… hey I have a projector and a laptop.
If you missed it in the comments to an earlier post. There are two new wikis you might want to keep an eye on as a NSW DET teacher (or any Maths teacher really).
The NSW DET will shortly equip Year 9 students with a Lenovo S10e netbook as part of a program called “Laptops for Learning” (L4L). To me, if we are going to do this – then it’s time to include some good software on these machines and help out schools who cannot afford some of the more exciting applications.
When starting “Volume” with Year 8, we start by looking at cubic units and isometric drawings. This year, with an interactive whiteboard (although, these resources are also suited for use with just a projector or in a computer lab), I was able to use a couple of excellent online resources.
Term 3 will see the roll-out of netbooks to Year 9 at my school (some photos of the Lenovo S10e).
I’ve been thinking about how to prepare for this roll-out in my own teaching.
Here’s a PowerPoint file I made to quickly review transformations before getting into congruency.
I need to learn to use GeoGebra because it looks like a fantastic app, it’s free and shortly our students will have their own netbooks, itching to use them. I find the best way to learn new software is to do something with it that you need.
This may be the first of several posts as I review the effectiveness of having an Interactive Whiteboard in my classroom.
The last week of term begins next week…
I have watched with interest the Digital Education Revolution proposed by the Australia Government. Issues of cost seem to have been resolved and I’ve resigned myself to the fact that the NSW DET is pushing a one laptop fits all model (although I think it’s flawed). I’ve read the tender for the “DET Learning Device” and have even dissected it with my computing class. But today, 1st April – fitting really – a significant step to realisation has been taken with the announcement of the hardware and software to be supplied.
In a previous post I talked about the Digital Education Revolution – the roll-out of student laptops. There will probably be quite a few posts on that topic this year.
2009 will be my fourth year of teaching. There are a few things happening this year that I want to note now, so I can reflect on their outcomes at the end of the year.
Some of the methods in this article do not work in Microsot Word for Mac 2011. Please see the updated post Mathematical Symbols in Word for Mac for a screencast describing the current best method (in my opinion).
Creating a maths worksheet in Microsoft Word without using the proper symbols does not present well – I’m sure you’ve seen 2 * 2 = 4 or 2 × 2 = 4 rather than 2 × 2 = 4. My previous post, Maths symbols in Word is one of the most popular on this site. In that post, I gave shortcuts for inserting mathematical symbols into Word – the post was specific to the Windows version of Word. As I’ve been a Mac user for a year, it’s time to make a similar post for Mac users.
Around this time each year, our programs have Year 8 and Year 10 looking at the Number Plane. For the end of the term, it’s nice timing, because it allows us to draw some pictures on the number plane. One favourite is the logos of various
Two very handy fonts that will help make worksheets and other computer created resources look great.
Google have added a nice little feature to their online spreadsheet – the ability to collect information via an online form.
Another game, this time for the most basic “technology” in the maths classroom – the calculator.
One of the difficulties I found in my first year, was using technology in the classroom for the teaching and learning of mathematics.
