I like this emphasis in the video; I suppose because it fits in with my own way of teaching logs!
With Curiosity Rover very much in the news this week, it seems a good time to highlight the educational resources available from NASA. Space Math @ NASA introduces students to the use of mathematics in todays scientific discoveries. The site includes Mathematics in the news – a look at the Mathematics involved in NASA press releases together with resources.
Note the Problem Books and Problem Archives which contain an extensive collection of problems. Several booklets are also available, see for example Exploring Space Math. Booklets include introductory pages including a table showing the topics covered by each activity. Why not use some solar wind magnetism data when teaching directed numbers or use solar flares when looking at equations and substitution?
David Watkins has provided an extensive, easily searchable collection of Excel Mathematics worksheets on dynamicmaths.co.uk. As you can see from the above image (his Algebra-01 sheet on simplifying linear expressions), these worksheets can be customised to suit a particular class. As well as a class activity, these could make excellent starters or plenaries, I think they would also be useful for student self-study / revision.
For another excellent collection of spreadsheets investigate the resources on Mike Hadden’s MathsFiles site.
