#### What skills will students develop at this level?

• Develop fluent knowledge, skills and understanding of mathematical methods and concepts
• Acquire, select and apply mathematical techniques to solve problems
• Reason mathematically, make deductions and inferences, and draw conclusions
• Comprehend, interpret and communicate mathematical information in a variety of forms appropriate to the information and context.

#### How will students learn at this level?

Mathematics is taught using a variety of techniques including the use of calculators but also written methods. There are opportunities for students to work individually, in pairs and in small groups. Students are expected to be able to explain their methods and show workings to support their answers.

#### How will students’ learning be assessed at this level?

Students have a test approximately one per half term covering three modules of work at a time.  They also have homework set weekly.

#### When do key assessments take place?

In June, soon after half term Year 9 students sit summer exams covering all of the work done during the year.

#### How can parents/carers support students’ learning?

• Monitor that your child is doing homework set to the best of their ability and is being proactive when they do not understand.
• When a test/exam is coming up, there will always be revision sheets provided. Make sure that your child uses them when revising, possibly redoing questions they have had difficulty with.
• Encourage them to work on My Maths or Maths Watch to look up topics they need more support or further practice on.

#### What equipment do students need for this subject?

• Scientific calculator – can be purchased from school
• Pair of compasses
• Protractor
• Ruler
• Pen
• Pencil

#### How does mathematics link to other subjects?

Science and Technology - Science and Maths are intimately connected, particularly in fields such as chemistry, astronomy and physics. Students who can't master basic arithmetic skills will struggle to read scientific charts and graphs. More complex Maths such as geometry and algebra can help students solve scientific problems. Maths is also important in practical sciences, such as engineering and computer science. Students may have to solve equations when writing computer programs and figuring out algorithms.

Humanities - Humanities often require students to review charts and graphs that provide data or information. Knowledge of basic mathematical terms and formulas makes statistical information accessible.

The Arts - Musical rhythm often follows complex mathematical series, and Maths can help students learn the basic rhythms of dances used in ballet and theatre performances. Art thrives on geometry, and students who understand basic geometric formulas can craft impressive art pieces.

#### What websites or resources may be helpful to support students’ learning?

MyMaths

BBC Bitesize for Key Stage 3

vle.mathswatch.co.uk

CGP Key Stage 3 Workbooks and Revision Guides

#### What extra-curricular or enrichment opportunities are available for students in mathematics at this level?

• Lunchtime Maths club
• Hertfordshire Maths Challenge

#### What sort of careers can mathematics lead to?

• Engineering and construction;
• Accountancy and other financial services;
• Statistical analysis e.g. business, sport etc.;
• Encryption coding;
• Security;
• Visual presentation of data-media services;
• Catering industry and a myriad of other careers.

#### What does student’s work look like in mathematics at this level?

Students mostly work in squared exercise books or on worksheets stuck into the books.

#### How does mathematics support a broad and balanced curriculum, meeting the needs of all students, and developing traditional core skills?

Broad and balanced curriculum - Maths links to multiple subject areas using a range of skills. We deal with all major concepts of maths in every term. Many of the topics are covered in real world concepts.

Meeting the needs of all students - The students are taught in ability groups within their bands. There are different resources used according to ability.

Traditional core skills - Non-calculator techniques are emphasised throughout and mental problem solving skills are encouraged. Students are taught how to use a calculator, checking the output makes sense rather than just blindly believing the answer given.

#### How does this subject promote creativity, critical thinking, practice, perseverance and resilience, and making links?

Creativity and critical thinking - Problem solving and making links between different concepts.

Practice, perseverance and resilience - We actively encourage students to revise for tests and exams and to always have a go at a question

Making links - Where possible, links are made between different subject areas such as Geography and Science.

#### How does this subject encourage enrichment and the development of cultural capital, deep learning, and inclusivity?

Enrichment and cultural capital - Links are made to a variety of other subjects from science, economics, music, art.

Deep learning - Topics are presented in different contexts to encourage the use of different strategies and deeper understanding

Inclusivity - The context of questions is closely monitored and adapted if necessary
