How do you make a unit on percentages richer / project-based / engaging / authentic?

Teacher’s all have their own way of keeping track of student attendance, and other aspects that are recorded in class. Here’s mine, it might give you some ideas.

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.

A Digital Education Revolution (DER) laptop in the hands of all Year 9 students changes everything… or does it?

In my IST class, we’re studying Modeling and Simulation, and started to make a model of a dice using Excel.

Thinking about it, the technique involved in making this would also be of interest to Maths teachers.

In this second post about using Excel to generate random questions, the first showed how to make a question about money, I show the simple formulae used to generate questions using the 4 basic operations.

Excel, part of Microsoft Office, is great for working with numbers.  For a maths class, Excel can be used for standard applications like working with tables of data and creating graphs.  Other teaching and learning applications that I’ve seen include creating self-marking computer based worksheets, interactive worksheets using sliders and even randomly generating questions for paper worksheets. 

Many teachers use Microsoft Word to create worksheets.  It’s not designed for the job, there are better options but Word is the easiest to learn and has the greatest compatibility - making it easy to share documents.  One of the problems I see is that many people don’t know how to insert symbols into their document.  For example, x (the letter) is not a good substitue for × (the multiplication symbol).  This post shows you how to insert symbols like ×, ÷ and π quickly, on most computers (a Windows PC running Microsoft office).
