Averages! (MMMR, From stem and leaf, From frequency tables, Comparing data)

Everything you need to teach finding averages in KS3 and 4!

Here are some of my favourite lessons for teaching finding and comparing averages. This is including finding and comparing mode, median, mean and range from a list of data, from a stem and leaf diagram and from a frequency table!

All lessons contain:
5 a day starter,
learning objectives with progress tick sheet,
Fully animated and clear examples,
Differentiated, colour-coordinated questions WITH answers.

Lesson 1:
Mode, Median, Mean and range.
Explanation and clear examples of finding each average. Includes individual questions to complete, as well as activities which can be used as extension challenges or paired work, such as odd one out and working backwards to find the numbers which gives you that average.

Lesson 2:
Stem and Leaf diagrams.
Whole class introduction to creating and using Stem and Leaf diagrams using class info for everyone to be involved. Short exercise to ensure students can create stem and leaf diagrams correctly. Clear examples on how to find averages on the stem and leaf diagram with individual questions. Extension questions comparing averages from a dual stem and leaf diagram.

Lesson 3:
Averages from a frequency table.
Clear, well paced examples for the whole class to go through, with time for students to work through one average before moving onto the next. Finishing with two individual frequency tables to ensure progress and full understanding.
Worksheet included.

Lesson 4:
FREE BONUS LESSON!
Comparing data.
This is a lesson I found on TES and loved to finish off finding averages. I have adapted it slightly so feel free to do the same, but I couldn’t leave it off as I think its a great group work lesson to finish the topic, or even make display work from!
Explanation of Primary and Secondary data, then given data from Olympians to compare to find who should be on the GB team. Great way for students to work together and practice answering questions with full sentences.

These are all my favourite lessons from the averages topic and I hope you enjoy them too! If you like them or think I could improve them in anyway, please rate or comment!
