Transformations – reflections, rotations, translations

Maths lessons, Resources

The Pac-man activity was a great resource to work through when I did it once with 7 Supp – not only for thought provoking start to the concepts but to re-visit later on as well.

Another lesson with understanding reflections as their goal is from Dane’s sight here.

Indices, Exponents, Powers

Maths lessons, Resources

Varied names around the world for the same topic! A key starting point in looking at this though is probably Michael Fenton’s blog on the topic, in particular noting the way he talks about the indices as ‘number of factors of’. This idea is talked about further here on Sara’s site where she also includes some other ideas worth looking at. I found the factors idea particularly helpful when discussing fractional indices (it was one of three ways I looked at it – the other of the two ways I think students found helpful was just recognising, for example, how 9^1/2 x 9^1/2 = 9, therefore 9^1/2 must be 3).

Solving Equations

Maths lessons, Resources

Wanted to pool a few resources here that I have come across to use for solving equations – there’s a mix of one-step and two-step stuff out there of course and one with a number of ‘game’ type activities was here from Izlomek.

I also thought Sarah Carter had some good resources on her site that she provides downloads for etc. for free. A number of these were one-step or variable on one side, but there were also some for variables on both sides and some overall rules to follow.

Scientific Notation

Keen at this point just to make a reference to Sarah’s page with a stack of activities around scientific notation. I’m going to try some of these out and ideally report back on here any reflections.

Shame it’s superbowl and not Aus-centric, but this post also has a nice activity around advertising but with some more thought provoking questions as well.

Measurement Starter Question

Maths lessons

During measurement topic, ask the students, how can a shape be both bigger AND smaller than another. For example, I used this doing perimeter and area of a semi-circle. I drew two diagrams on the board with particular dimensions where one with the smaller perimeter had a larger area. It would work with many different ones though and could be used for example to show how the largest area for a ‘rectangle’ is when the sides are the same (ie. a square). On this last one, there was a good site I came across for exploring this – complete with video and an image I turned into a worksheet (Perimeter v Area). Also later discovered this resource looking at which shapes have the greatest area (with links to further resources!)
