1. Starter – the area of which shapes can be found with the following formulae?

2. Find the area of each shape:
5cm cm cm
7cm cm cm
5cm cm
12cm

3. WALT – use appropriate mathematical procedures
WILF – select appropriate calculations; manipulate numbers;
use the correct notation; record methods, solutions and conclusions

4. Found a solution? – find another....
A cuboid has a volume of 120cm²
What could the dimensions be?
Found a solution? – find another....
and another...
How many solutions can you find?

5. Record methods, solutions and calculations
Collaborate as a team, working towards the common goal
Manipulate numbers
Convince me that there is only one cuboid with a volume of 240cm³ and a surface area of 248 cm²
Use the correct notation
QWC
Select appropriate calculations
Organise your time; prioritise actions

6. Self and peer assessment
Looking at the recorded methods, solutions and conclusions have you / they met the success criteria?
Give a score out of 5 for QWC
Were the appropriate calculations selected?
Is the working out correct (manipulation of number)?
Has the correct notation been used?
