I am an experienced Maths teacher, currently working in Madrid Spain.
I have made hundreds of resources over the years and wish to share them.
The majority of my resources are for use with promethium software, but I can also translate them to Smartboard on request.
Powerpoint slides to use to practise working out the perpendicular gradient of lines.
Pupils draw a 3x3 grid and copy 9 of the gradients down into their grid.
