Micro Teaching - Trigonometric ratios of special angles in standard position Lesson Plan

-
Here is our lesson plan for tomorrow's micro teaching.  The plan is a bit ambitious - our team is still working to consolidate it.

    Thanks Ellen, Sue and Vincent! This is one of my favourite curricular topics.

    I think the lesson you've planned is too long for the given time, and I would recommend dropping the review of sin, cos and tan at the start. It's not really part of this topic, and you don't have time to do a review.

    In the main body of the lesson, be careful not too: a) concentrate TOO much on 'tricks' (as it can lead students to believe that math is all just a big list of meaningless magic tricks that you have to memorize exactly). Mind you, the tips and tricks you are showing sound very interesting -- they are ones I have never encountered!

    b) Make sure that the lesson is not all just teacher-talk and explanation -- be sure to have some student participatory engagement, even in this short micro teaching lesson!

    c) Make sure your 'hook' is more than just saying the topic of the lesson. (For just one possible example, can you offer some kind of interesting teaser about the fact that triangle trig is now going to transform into circles and sinusoidal curves?) The 'hook' should be brief but also intriguing.

    c) I don't think you'll have time to deal with ACTS/ CAST and the signs of the four quadrants in this very short lesson. Stick to what can actually be accomplished in 15 minutes, rather than trying to pack in more! It will give you space to really do a good job with the teaching.

    Thanks! Looking forward to a great lesson.

Summary observations of the term blog

-
Upon review of the blog from this term in this class, I find a nice selection of teaching philosophies and styles discussed in the articles.  The articles suggest ways that we can direct our own teaching practice and give some examples of how a method has been used in the past.   In addition, we reflect on our own reasons for choosing math and our reasons for becoming teachers.  Finally, there is a nice selection of reflections from my own practice teaching (micro teaching) that are interesting to look back on. Finally, there is the most fun and interesting ideas for math puzzles/riddles that I solved or at least tried and that I can use in my own classroom to stimulate discussion and spur creative math thinking. All and all an interesting selection of resources to have for future use.  Thank you.

'That man' - riddle

-
Brothers and Sisters have I none, But that man's father is my father's son. Who is speaking?  'That man' is speaking Who is 'that man'?  That man is the speaker What makes this riddle interesting?  When I considered that 'that man's' father is my father's son, I initially thought 'that man'  was a brother.  However, we know that the speaker has no brothers (or sisters) so that makes it interesting.   The only explanation that I could think of for the riddle is that 'that man' is the speaker's reflection or something similar.  Initially I did think that the riddle referred to two individuals.  However, I could think of no other solution than the one of the speaker reflecting on himself.

Sues entry-slip: Mathematical Representation

-
Mathematical Representation What convinces (or doesn't convince) you in the author's argument?   I fully agree with the author in that representation is fundamental to the development of a student's mathematical understanding. What convinced me was the simple fact that pictures help kids (and adults)understand. I have to confess, I was unfamiliar with the terminology before starting the article and had a very difficult time getting through it. Had I googled the terminology before reading, I would have seen all of the pictures and examples and better understood the context and direction of the material. On further exploration, I realized that the author is really explaining what is, to my mind, the easiest and clearest way to work. What kinds of mathematical representations are included and excluded in the artcle?   The article includes references to representations such as: numerals, algebraic equations, graphs, tables, diagrams and charts, and an example of simpli...
