A few subs and some calm heads prevailed, and the next 5 minutes belonged to HAO. A penalty awarded that Solomon dispatched comfortably to make it 5-4 to HAO. The team held on for the final 2 minutes to take the win. A close and very tense game but still a victory for HAO. pic.twitter.com/hJ9t9snn5a

The second half started with confidence, precision and good decision making as HAO went up to 4-0 by the 50th minute. However, upped their game and something shifted as they clearly dug deep, bringing the score to a nail biting 4-4, and only minutes left. pic.twitter.com/5h35Z1XkyE

Maths

The Harris Federation schemes of learning have been written in line with the aims and ethos of the new National Curriculum and assessments. This has been an exciting opportunity to re-examine the principals of how we teach Mathematics across the Federation and these schemes of work are adopted at Harris Academy Orpington.

We have designed our curriculum such that it reflects the linear nature of Mathematics with opportunities to revisit and consolidate learning so that concepts are not superficially covered but learnt and understood in greater depth. We took the programmes of study from the Department for Education for both Key Stage 3 and Key Stage 4 and have created a curriculum with a five-year course, with exemplar activities and resources to support students learning.

Academy mathematics leaders and teachers are regularly consulted about the curriculum and their feedback has informed further development of the scheme of learning and professional development for our teachers so that our curriculum and delivery are continuously being improved. The mathematics consultant central team see professional development as key to improved learning outcomes for students.

During the years following the initial development of the scheme of learning, Mathematics teachers have received high-quality professional development through London Thames Maths Hub and Federation INSET days and have had opportunities to discuss, collaborate and share ideas and pedagogy to strengthen the schemes of learning and their own professional learning needs. 

Harris Academy Orpington has adapted the schemes of learning to ensure it is the best possible curriculum for the cohort of students and to also consider the individual context of the School including the number of lessons they have each week and the timings of their lessons.


What is the intention of the curriculum?

At Harris Academy Orpington we believe that all pupils, regardless of background, have the right to access a high-quality Mathematics curriculum – a curriculum that is both enjoyable and challenging, and where challenge is provided through depth rather than acceleration. Through the study of the principal strands (proportional reasoning, geometric reasoning, data handling, algebra and number) our curriculum is designed to create opportunities that allow pupils to make connections, within the discipline, and across the wider curriculum.

The purpose of our curriculum is to empower students to develop and apply problem-solving skills as they explore and learn Mathematics in a way that sparks their curiosity and builds their resilience. We equip our students with the skills and knowledge to empower them to improve their numerical literacy supporting them in the world we live in. We want to ensure that all teaching across key stages is purposeful, builds on previous knowledge and sequenced to ensure pupils learn more, do more and remember more in Maths lessons.

With our curriculum we aim to support and engage all students to achieve high levels of mathematical reasoning and problem solving whilst helping pupils to develop not only a deep but a secure knowledge and understanding of Mathematics that will remain with them at each stage of their learning.


How will this be implemented?

Subject expertise allows the intentions of our Mathematics curriculum to be executed successfully. Teachers use their subject knowledge to cultivate a classroom culture where the discussion of mathematical ideas is promoted and through these discussions mathematical vocabulary is expanded. Each teacher has autonomy in the classroom. However, we choose to plan lessons and activities as a collective, together developing a range of different activities to engage students in improving their reasoning and problem-solving skills.

Our schemes of work are built on the foundation of skills and knowledge acquired during Key Stage 2. We take time to ensure that students have the pre-requisite skills to maximise their participation and engagement, developing confident mathematicians who are not afraid to take a risk.  The interleaving design of the curriculum means that topics are revisited throughout the course and addressed in further depth each time, again building on prior knowledge.

For some students at Harris Academy Orpington it is appropriate to provide them with additional Maths support. These are identified though initial assessments and all pupils continue to be reviewed to ensure pupils receive appropriate support. We have specialist teachers delivering Target Maths sessions that aim to support pupil confidence with key mathematical ideas and work alongside the curriculum to maximise pupil progress and build a strong foundation of mathematical knowledge.

Following the completion of each unit (topic), an assessment is completed. This provides an opportunity to determine students’ strengths and weakness and thus informs our planning. Following assessments, summative and formative, we further consolidation or offer greater challenge where appropriate.

For homework, we use Hegarty Maths where students are set personalised task with videos for support. The homework platform allows the opportunity for habitual practice which support students commit their maths skills into long term memory. Students also complete quizzes which review skills which they have previously covered.


How will we judge the impact of this curriculum?

When students come to the end of their time at Harris Academy Orpington, they can think, talk and act mathematically. They are confident in applying their knowledge to enable them to be both financially and data literate, skills which will allow them to positively contribute to society in any field they choose. They have developed an understanding of the beauty and the relevance of mathematics in our society and many will continue to study maths Post 16.

Key Stage 4

The mathematics schemes of work for Key Stage 4 broadly follows the AQA new GCSE mathematics 8300 specification and builds on students prior learning from Key Stage 3.

Students will follow either the foundation or higher scheme of work depending on prior assessments and teacher judgement based on classwork and independent work. Problem-solving is at the heart of the new curriculum and opportunities to develop problem-solving and reasoning skills in maths are embedded within each unit of work.  Once students reach Year 11, their teachers will decide upon how much they need to deviate away from the scheme of work based on thorough assessment. This takes place in lessons and through whole school mock exams.

The new Key Stage 4 curriculum is focused on students developing mastery of mathematics and involves:

-  developing fluent knowledge, skills and understanding of mathematical methods and concepts
-  acquiring, selecting and applying mathematical techniques to solve problems
-  reasoning mathematically, making deductions and inferences and drawing conclusions
-  comprehending, interpreting and communicating mathematical information in a variety of forms appropriate to the information and context.
