This is a look at the basic averages in terms of comparative strengths, by using a rich task. This is a great way of promoting understanding of averages as well as consolidating previous learning.
It comes with the usual starter, learning objectives, a HELP SHEET for the less able pupils, activity with answers and plenary. The help sheet and worksheet are included. I teach the following lessons on averages in the following sequence:
1. Basic Averages (mode, median, mean) and the Range
2. What average is best (rich task)
3. Grouped Data - Finding the estimated mean
4. Grouped vs Non Grouped data (practical lesson)
All lessons are available in my shop as well as a bundle at a reduction per lesson.
