This is a look at the basic averages... i.e. non grouped data!!
It comes with the usual starter, clear teaching, averages rhymes (the main problem for pupils is mixing them up, not being able to do them) activities with answers and plenary. The excellent teaching PPT comes with a TARSIA activity and a averages maze.
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)
