This task is based upon the common pyramid structure. It gets quite challenging, rather quickly. There are a few basic ones to gives kids some confidence but after that the demands ramps up.
Question 12 is designed as a real challenge for pupils working at early secondary level.
I have included the condition of not using zero, but you can add more, which I would do:
- Can you try to complete a pyramid without repeating a fraction appearing twice in it?
- Fully simplify all of your fractions
- Try to do as much of this mentally as possible. Only use written methods when you absolutely need to.
