Key Stage 3 Maths

Subject: Mathematics

What will students learn?

  • Much of year 7 focuses on developing students’ proficiency in number and basic geometry, which will form the basis of their mathematical knowledge. We prioritise developing students’ automaticity of number facts at the start of KS3.
  • In KS3 we highlight the connections between number, algebra and geometry, for example, using bar modelling as a bridge from arithmetic to early algebra and ratio. We teach robust procedural knowledge such as that surrounding formulae and solving equations; this enables student success in KS3 and sets them up for KS4, KS5 and beyond.

In KS3 students will study

Year 7

Place value and our base 10 number system including rounding and working with the four operations. Area of rectangles, triangles and parallelograms. Calculating with decimals and working with fractions. Angles and measure including the properties of 2-D shapes and symmetry. Introduction to algebra including manipulating expressions and negative numbers. Basic probability.

Year 8

Properties of numbers including prime factors, squares and roots. Application of negative numbers including fractions and the four operations. Solving algebraic equations. Rounding and estimating numbers, including using a calculator. Angle properties and angles in parallel lines. Introduction to circle geometry and area of trapezia and compound shapes, including unit conversion. Speed and distance-time graphs. Working with percentages, ratio and proportion. 3-D shapes, volume and surface area. Comparing and analysing data.

Year 9

Coordinates and linear graphs. Angles in polygons. Converting to and from standard form notation. Working with sequences. Expanding and factorising. Ratio, proportion and scale. Forming and solving equations and inequalities. Index laws. Pythagoras’ theorem and transformations. Comparing and analysing data including further averages. Probability.

How will students receive feedback?

At Paddington, all students will receive regular feedback from formative assessment tasks. Within the curriculum, specific tasks are allocated for feedback. This ensures all students gain regular feedback. Teachers will mark student work and provide targeted feedback that enables students to improve their work and make progress. To support student understanding, teachers plan high-quality re-teach time to prepare students for their feedback. Across each term, students will receive feedback from multiple tasks.

What resources can be used to support learning?

  • All KS3 students at our school complete their homework, revision and independent work on SparxMaths.uk
  • The 100% books contain the knowledge organisers with core knowledge for each cycle. Students can use this to revise key information through self-quizzing.
  • The United Learning curriculum website has resources and lessons that can be used to support and extend the content covered in lessons.
