Mathematics Subject Special – UKEdChat

The UKEdChat Mathematics Subject Special was on Thursday 23rd October, the previous link now includes a record of the chat.

Note the questions raised during the chat:

1. What are some of your key mathematical questions you use in lessons? Share your favourite maths starter activity.
2. What are your favourite maths resource sites for inspiration? Who are inspired maths tweeters you follow?
3. Which maths topic do your students struggle the most with? What support strategies do you use for them?
4. Homework … Which are the most successful strategies you use for maths?
5. Maths and computing go hand in hand. How are you tapping into this connection?
6. Final call. Please showcase your favourite aspects of maths teaching / resources / tips.

I have mentioned many resources you may find useful in connection with many of the questions in my ‘Resolutions for Mathematics Teachers” reproduced here:

It started with a tweet!

I noticed a tweet from Darren Kuropatwa..

Here is what Darren was referring to, a video made by Desmos on exploring the sine function:

Sine function created on Desmos by Darren Kuropatwa

Darren has recreated that graph here.

Now I rather like that and thinking it would be useful for my revision session this week with a GCSE (UK age15-16) class, decided I would simplify it so it was more suitable for my students. I changed  the units to degrees and restricted the transformations more so it was more in line with our specification (these students are studying for a second GCSE in Mathematics – AQA Further Mathematics level 2).

Along came Desmos having seen the Twitter conversation..

and look at the awesome graph Desmos created which shows a sine curve and a transformed curve clearly illustrating how each point is changed.

We could for example translate the curve 2 units parallel to the y axis:

Using the slider for angle we see very clearly that each y coordinate is increased by 2.

Brilliant!

Thank you Desmos (and Darren!)

Happy Easter

Happy Easter 2017! (Click the link and WolframAlpha will tell you more than you wanted to know about Easter Sunday!)

Since it’s a holiday we should be relaxing! Why not try the excellent Set Game – a daily puzzle?

Wishing you all a very Happy Easter.
