How many? (Pick something you can say “how many” about. Write just the number on the board.) You have to know what a number measures/counts for it to be meaningful. Maths Learning Centre at UofA: www.adelaide.edu.au/mathslearning
100 people 2 kg 5 hours When is this big? When is this small? When is this in the middle? Numbers are only meaningful by comparison. Maths Learning Centre at UofA: www.adelaide.edu.au/mathslearning

You are now SQUEETLES – you each have a card showing what you look like and how high you can jump. • (The grey number is just there so I can make sure I get all my cards back later.) • I’ll rearrange you into several bigger groups. • Compare your squeetles to each other within your groups.

Choose one squeetle from your big group who best represents the whole group’s jumping height.(Don’t take into account the patterns.) • Send your representatives to the front and we’ll talk. Averages help to compare numbers between groups, but don’t necessarily represent individuals. Maths Learning Centre at UofA: www.adelaide.edu.au/mathslearning
Choose one squeetle from your big group who best represents the whole group’s body pattern.(Don’t take into account the jumping heights.) • Send your representatives to the front and we’ll talk. Percentages help to compare groups in terms of more or less in a category (since there is no such thing as a representative category). Maths Learning Centre at UofA: www.adelaide.edu.au/mathslearning
What we’ve seen so far: • You have to know what a number measures/counts for it to be meaningful. • Numbers are only meaningful by comparison. • Averages help to compare numbers between groups, but don’t necessarily represent individuals. • Percentages help to compare groups in terms of more or less in a category. • THE STORY IS WHAT MAKES THE NUMBERS MEANINGFUL Maths Learning Centre at UofA: www.adelaide.edu.au/mathslearning
A word problem in the classic style: Squeetles are the latest pet craze! An online poll asked people to choose which of striped or spotted squeetles were cuter.
