# Key Stage 3

Curriculum Intent
At St. Saviour’s and St. Olave’s School, we intend for all learners at KS3 to:

• Secure and deepen their understanding and confidence with number work and calculations
• Develop understanding of geometry with 2D shapes, 3D shapes and angle facts
• Develop an understanding of algebra and progress into graphs and transformations
• Practice and develop skills in fluency, reasoning mathematically and problem-solving
• Be numerate and develop functional maths skills
• Experience a diverse and inclusive education
• Explore enrichment opportunities
• Enjoy and feel confident in maths

What will students learn about Mathematics at Key Stage 3?

During Key Stage 3 Students will aim to develop their mathematical understanding in these Key areas:

Number & Algebra:

Students discover how the use of number and algebra are closely related. They will learn how to apply the four rules (Addition, Subtraction, Multiplication & Division) as well as developing their understanding of proportions (Fractions, decimals percentages) and ratio. Students will put these skills to the test by solving problems in different contexts, some of which being unfamiliar to them.

Geometry & Measures:

Students will learn how the number system and the measurement system now work in harmony together since our system of measurement was made metric in the 1970’s. This understanding is vital as it underpins students’ understanding of other concepts such as Area, Volume, Speed and other measures used in everyday life. Understand our measurement system is important for students to become a fully functional part of society. Students will also explore Geometry, the study of the everyday shapes we see around us that subtly influence us. Students will once again put these skills to the text in a variety of different contexts, sometimes linking in to Number & Algebra.

Data Handling:

Being able to collect, interpret and analyse information is a massively important life skill. In key stage 3, all students will have the opportunity to develop these skills. They will do this through undertaking their own statistical investigations and learning techniques for analysis and evaluation of their results.

Using and Applying Mathematics:

Being able to use and apply mathematics in a variety of different contexts is a massively important skill. Not only is this skill becoming far more important in the assessment of pupils, it is also very important for students to be able to function on an everyday basis and in their future careers. Mathematics is all around us: Telling the time, reading a bus timetable, calculating costs, measuring temperatures, putting up shelves, planning a journey, manufacturing a mobile phone, making food products, estimating profit margins, making a building, engineering a car. These are the sort of everyday activities students will be solving problems in on a regular basis in Mathematics.
