Objectives
‘How can we apply algebra and graphs when solving problems and proving it works?’
Week 1 (B): Why does having X2 in an equation create a curve in a graph? (Deeper thinking: is there a relationship between and
hyperbola and the function 1/x?)
Week 2 (A): How do we graph inequalities?
Week 3 (B): How can we solve simultaneous equations using graphs?

IMPORTANT INFORMATION AND WEEKLY NEEDS
Personalised
Learning and
Reach work
and Mastery
Maths in real
life
Planning for
Feedback
REACH and
Support
The AQA objectives above cover a wide range of mathematical skills and applications at varying levels of difficulty.
Each practitioner has access to sets of exam based questions and activities that are aimed at these different levels of
application and will ensure that all pupils are provided with work that will both challenge and support them at their targeted
Grade Point as well as pushing them towards the next. All pupils will meet the progress objectives outlined above at a pace
that suits them and will be delivered in a way that is personalised to how they learn. The use of iPads will be planned for
carefully so that they can maximise learning.
Each week, there will be discussion and slides planned in so that pupils can value the relevance of what they are learning,
which areas of life or careers that skill may be useful to and lessons will, as much as possible, contain resources where maths
has to be applied to real world problems in order to find solutions. Percentages for instance, will be applied to calculating
interest, value comparisons and rate of change.
Pupils will receive written feedback each week in the form of teacher marking, peer/self-assessment and small quizzes to check
key knowledge. Mark schemes will be provided where appropriate for pupil self-assessment and development. REACH lessons
each week will allow time for acting on feedback and making improvements to their work in order to develop further and fill in
GAPs. To extend mastery in learning REACH lessons will now also include extension problem solving tasks.
Each week there will opportunities for support with in class intervention, group intervention and after school catch-up.

homework
Lesson 1 of the week: REACH lesson – improving my mastery of drawing, completing, sketching and interpreting graphs.
Pupils will use this lesson to engage with and respond to work marked and done the previous week. They will read through teacher
comments and respond by following a given set of criteria. This will allow them to make improvements on their work, carry out
corrections, seek help and make further progress before moving to the next unit of work. To extend their knowledge of the content from
week 2 pupils will be given examination type problems from the new GCSE specification at and above their targeted grade point to
stretch their comprehension. Real life application and problem solving will be provided as REACH work linked to their feedback.
Hypothesis 1 – (This will take 2 lessons to cover the content within the AQA objective) You can prove that triangles are
congruent without mathematical reasoning.
Learning intention: Apply angle facts, triangle congruence, Pythagoras’ Theorem, similarity and properties of quadrilaterals to
conjecture and derive results about angles and sides including the fact that the base angles of an isosceles triangle are equal, and use
known results to obtain simple proofs.
GP 3 – 4 = Recall shape properties important to quadrilaterals and triangles. Describe with examples the term congruent and similar.
Prove algebraically that angles in quadrilaterals add up to 360 degrees.
GP 5 = Understand how to apply Pythagoras’ Theorem to prove that a triangle is right-angled. Evaluate by applying algebra if 2 triangles
are similar/congruent.
GP 6 – 7 = Apply trigonometry to evaluate similarity or congruence in triangles.

arguments and proofs
GP 3 = Recall types of number, particularly prime, odd and even.
Examples;
1. Amy says that for every whole number, 6n – 1 is always a prime number.
Give a counter example to show that she is wrong.
2. Prove that the answer to every line of the pattern below is 6
3×41×6
4×52×7
5×63×8
6×74×9
3. Below is Joe’s attempt at forming a proof that 1 = 2
Let a = b

ab = b 2
(multiply by b)

ab  a 2 = b 2  a 2
(subtract a 2)

a(b  a) = (b  a)(b + a)
(factorise)

a=b+a
(divide by b  a)

a=a+a
(a = b)

a = 2a
(a + a = 2a)

1=2
(divide by a)
Which step in Joe’s argument is not allowed?
