I am not sure why there wasn't a set of exercises on speed till now... That's speed/distance/time just in case you'd taken that the wrong way!

Mathematical Miscellany #101
A compilation of mathematical goodies! It is so important that students check answers for reasonableness, yet they frequently don't. Examiners frequently report that students lose "easy" marks by providing answers that are physically or mathematically impossible. Checking answers can make a difference in students' grades. For example, always sanity-check real-world results. I once had a student calculate an individual’s height as 4 cm.

I've added a new section to the site today - A-level Revision. Over the next few months I hope to add to the revision resources, starting with four A-level grids - algebraic methods, quadratics, exponentials and logs, and circle geometry.

Specialise, Conjecture and Generalise. A three-step plan to encourage and develop mathematical thinking. I'm going to use this thread to share a few of my favourite tasks that lend itself nicely to this idea. It would be amazing if everyone added their own in the replies.

GCSE Maths resit entries are up on last November by 4.6% to 75203, but the number achieving grade 4 or above has stayed much the same (well, up by 0.5%) at 16800 or so (allowing for rounding errors)

I have drawn a line under my GCSE Maths videos. I completed all of Number and Algebra for both Foundation and Higher, across 862 videos and 68+ hours. It took me 3 years to make them all but I've sadly decided to end it there. Hopefully they are useful!
