Age 5 to 11
Challenge Level
When I went into a classroom earlier this week a child rushed up to tell me she was 8 that day.
Well, Happy Birthday to everyone who has a birthday today!
This challenge is about finding a variety of ways of asking questions which make 8.
You might think of 6 + 2, or 22 - 14 or...
However, try to create examples that use all the different mathematical ideas that you know about.
Perhaps you could challenge yourself to find ways of making 8 that you think no-one else will have thought of.
If you are not 8 years old, you might like to use your age instead of 8.
