Lesson 1. Introduction of Stem and Leafs

Starters, examples, plenty of differentiation throughout, stretch & challenge including problem solving and reasoning, plenaries and AFL. SMART Notebook files but can be converted to ActivInspire etc. Used in my PGCE year! Worksheets included, if I have missed anything off please let me know :) Sorry if any resources used, I gathered bits along the way.

(Starter is a 'beat the teacher' activity' whereby you ask students to give you a number and as they are giving you them you write them on the board in a stem and leaf (students write all the numbers in their exercise book) then compete with the students who can calculate the median the quickest.. you or them? - obviously from a stem and leaf it's a lot quicker so the students can see the relevance of it).
