3. What is mixed attainment teaching?
Classes that have a range of:-
Prior attainment,
SEN,
Pupil Premium
Attitude to Learning

5. Today’s Workshop…. Supporting all pupils with AO3 questions
Encouraging reasoning
Multiple Entry point tasks.

6. What is ‘Boxing Up’ and why do we need it.....?
Last years exam results show that even our highest achieving students at GCSE struggle to cope with the problem solving and reasoning elements of the GCSE exam….

7. Boxing Up is a ....... Strategy for working out (for writing)
Strategy for discussing (asking each other questions)
Strategy for thinking (asking yourself questions)
Aoife

8. What is the question asking me?
What information do I already have?
What Maths will I be using?
What calculations / working out do I need to do?
How can I check that my answer is correct?

9. A03 Question
The diagram shows a garden in the shape of a rectangle.
All measurements are in metres.
The perimeter of the garden is 32 metres.
Work out the value of x
(Total for Question is 4 marks)

10. What is the question asking me?
What information do I already have?
What Maths will I be using?
What calculations / working out do I need to do?
How can I check that my answer is correct?

11. Perimeter is all the sides added together.
What is the question asking me?
What information do I already have?
What Maths will I be using?
Find the value of x
Solve an Equation
Perimeter = 32 metres
Write an Equation
Perimeter is all the sides added together.
What calculations / working out do I need to do?
How can I check that my answer is correct?
4 + 3x + x x + x + 6 = 32
Substitute 1.5 for x and check that the perimeter does = 32
8x + 20 = 32
8x = 12
x = 12 8
X = 1.5

22. Multiple Entry Point Tasks …….
“Differentiation does not happen at some spurious notion of 3 levels; it happens at as many different levels of cognition and depth of sense making as there are students in the class.”
Mike Ollerton 2014
