Step 8 Objective
Use systematic trial and improvement methods and ICT tools to find approximate solutions to equations such as x³ + x = 20.
- Examples of what pupils should
know and be able to do - Probing questions
- What if pupils find
this a barrier?
Probing questions
How do you go about choosing a value (of x) to start?
How do you use the previous outcomes to decide what to try next?
How do you know when to stop?
How would you improve the accuracy of your solution?
Is your solution exact?
Can this equation be solved using any other method? Why?
