14 new Nspire files at www.HandheldGeometry.co.uk
Nevil Hopley
14 new Nspire files have just been added to the Handheld Geometry
website. Each one has it's own short preview video, as well as a
download link. They've all been used in my maths lessons over the past
4 months. They are all listed below.
A full text index of all 58 of my Nspire resources is here:

A full 'screenshot index' of all my resources is here:

Hoping that something here is helpful to someone out there!
