My first speaking session since leaving my role at Twinkl. Feels weird but strangely enjoyable to be preparing to speak at the next Complete Mathematics conference #Mathsconf41 using my old style PowerPoint template, rather than the Twinkl template.
Title slide with title "Time to revisit...probability" and my information for the session I am delivering at the upcoming Complete Mathematics Conference for LaSalle Education in Liverpool.
