Probability • Chances · Thinking deeper
Spinner designers
Make a six-section spinner where red is more likely than blue, and blue more likely than yellow. Draw a different arrangement with the same chances.
Give it a go
Try ideas with the activity tools, draw your thinking, or explain it in words. There may be more than one useful response. This activity does not save or submit your work.
What this explores
Probability as a proportion. The six sections have equal area, so likelihood depends on section counts rather than order. The wording allows zero yellow sections; discuss impossible outcomes as well as designs using all colours.
A starting nudge
Use equal sections. Moving colours around does not change how many sections of each colour there are.
Take it further
What additional condition would make every colour possible?
For teachers
