Science Learning Centres endorse Best Fit Line Rulers

Following the successful partnership between The Institute of Physics and BFLR, the national Science Learning Centre now have specially branded Best Fit Line Rulers to advertise their activities. At the same time, the National Stem Centre has also joined forces with BFLR to show that straight line graphs can advance the cause of the STEM subjects.

The BestFitLineRuler – BFLR -  makes locating and drawing the line of best fit on a line graph easy.  You can read all about it in the December 2009 issue of the IoPs Classroom Physics magazine.

Just lay the clear ruler over your graph, once data points have been plotted, and the grid on the BFLR will help you to make sure you get as many points as possible as close as possible to the central slot. Then slide your pencil along the groove and there’s your best fit line.

With centimetre and millimetre markings along the edges, it acts as a traditional ruler too.

The simple innovation behind Best Fit Line Rulers has proved a big hit with teachers and pupils alike.  Some  schools have gone as far as to provide one for every pupil.

“We reckon they’ll definitely help for GCSE,” said Andy Guest, Head of Maths at St Bede’s School in Lanchester, County Durham.
