Watch this video
i) What mathematics would be involved in the work you have just watched?
ii) What effect might watching such a video have on your learners?
iii) At what point in the lesson, might you show the video?
iv) If you did not have a suitable video to play, what else might you do to show learners the application of a topic?
You may find it useful to watch the video more than once. You should be able to find more than one point where mathematics is being used!
The Maths in Work microsite was been designed to offer glimpses of the real world of work via video clips, to help learners appreciate not only the relevance of mathematics but its importance in everyday life. The clips feature the people who are actually ‘doing the job’ and explain some of the maths processes that they are involved with on a daily basis. Teachers and trainers can find a brief synopsis of each clip on the Maths in Work microsite. This identifies the maths topics covered, and all clips end with the simple question, “What mathematics would be involved in the work you have just watched?”
Some people show the clip after they have taught the topic. Others show a clip at the start of a session and then after discussing what mathematics is shown in the clip, go on to teach that topic to their learners.
In this video we watched a process which involves the interpretation of graphs, measures and the use of formulae. SSL International manufactures and distributes health care products to over 130 countries. Becca is a stability analyst and in this clip is using an Atomic Absorption Spectrometer to find the amount of Sodium in a sachet of one of their products. The product is dissolved in water, and the spectrometer gives an absorption reading which can be applied to a graph showing a calibration curve plotted from known values. From this the concentration can be read which will indicate the weight of Sodium when applied to the appropriate formula.
If you are unable to show a video, you might want consider printing a suitable photograph or having a class discussion about the use of this topic in the ‘real world’ or inviting in a STEM ambassador or an appropriate parent or personal contact etc.
