Year 7 Maths Mastery: AQA Revision

What do you already know about Year 7 maths topics?

Learning Objective

At the end of the lesson you will be able to solve questions in number, algebra, geometry, and data topics for Year 7 AQA maths.

Place Value Essentials

Understand the value of each digit in a number, how to round numbers, and how to compare them.

Rounding Numbers

To round a number, check the digit next to the place you are rounding to. 5 or more means round up, less than 5 round down.

Comparing Numbers

Use <, >, or = to show if one number is smaller, bigger, or equal to another.

Negative Numbers

Order, add, and subtract negative numbers. Remember — on a number line, negative numbers are to the left of zero.

Factors and Multiples

A factor divides exactly into a number. A multiple is a result of multiplying a number. Find HCF and LCM of pairs of numbers.

Prime Numbers

A prime number has only two factors: 1 and itself. 2 is the only even prime number.

HCF vs LCM

Lowest Common Multiple (LCM)

Highest Common Factor (HCF)

The largest factor shared by two numbers.

The smallest multiple shared by two numbers.

Fractions: Key Skills

Simplify fractions, find equivalent fractions, and add or subtract fractions with the same denominator.

Fractions in Action

To simplify, divide the top and bottom by their highest common factor. To add or subtract, use a common denominator.

Decimals Mastery

Understand decimal place value and practise multiplying and dividing numbers by 10, 100, and 1000.

Percentages Explained

Learn to convert between fractions, decimals, and percentages. Remember: 'percent' means 'out of 100'.

Algebra Basics

To simplify, add like terms. Substitute by replacing the letter with a number.

An expression is made of terms. The number in front is the coefficient.

Simplifying & Substitution

Expressions & Terms

Solving Equations

To solve one-step equations, do the opposite (inverse) operation to work out the value of the letter.

Simple Sequences

Find the term-to-term rule, and use it to find the next term. Learn how to spot or use the nth term for simple sequences.

Types of Angles

Acute (<90°), obtuse (90°-180°), reflex (>180°), straight line (180°), and full turn (360°).

Triangles & Quadrilaterals

Equilateral (all sides equal), isosceles (two equal sides), scalene (all sides different).

Square, rectangle, parallelogram, trapezium — all have four sides.

Triangle Types

Quadrilateral Types

Perimeter & Area

Perimeter: add all sides. Area rectangle: length × width. Area triangle: ½ × base × height.

Bar Charts

Read and draw bar charts to show and understand data easily.

Averages

Finding the Mean

Add all values up and divide by how many values there are.

Types of Averages

Mean (add, divide), median (middle), mode (most), range (difference).

Probability Principles

Probability is the chance of something happening. Use scales from impossible to certain. List simple outcomes.

Practice & Key Tips

Work through practice questions. Remember to show working, check units, estimate first, and always read questions carefully!

Quick Formula Sheet

A = l × w Area of triangle = ½ × b × h

Area of Rectangle

Mean & Percentage

Mean = total ÷ number of values Percentage = part ÷ whole × 100
