Grid lines - a HCF and LCM investigation
Post 22/29 in the Staffrm #29daysofwriting challenge: An interesting way to investigate HCF and LCM
For my remaining full week, I'm going to try and post one rich resource and discussion. I found a nice prompt yesterday in a pack of really old investigations, and thought I'd look into it in a little more detail today. I'd got this filed under HCF and LCM, and have no idea of the origin, but it looked pretty simple so I sat down with pen and paper to try and figure it out.
