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?
Examples of what pupils should know and be able to do
Pupils should be able to use trial and improvement for equivalent problems,
e.g. A number plus its cube is 20; what’s the number?
The length of a rectangle is 2 cm greater than its width.
The area is 67.89².
What’s the width?
Pupils should have opportunities to use a spreadsheet for trial and improvement
methods.
