# Year 7 Key Objectives

- Simplify fractions by cancelling all common factors; identify equivalent fractions.
- Recognise the equivalence of percentages, fractions and decimals.
- Extend mental methods of calculation to include decimals, fractions and percentages.
- Multiply and divide three-digit by two-digit whole numbers; extend to multiplying and dividing decimals with one or two places by single-digit whole numbers.
- Break a complex calculation into simpler steps, choosing and using appropriate and efficient operations and methods.
- Check a result by considering whether it is of the right order of magnitude.
- Use letter symbols to represent unknown numbers or variables.
- Know and use the order of operations and understand that algebraic operations follow the same conventions and order as arithmetic operations.
- Plot the graphs of simple linear functions.
- Identify parallel and perpendicular lines; know the sum of angles at a point, on a straight line and in a triangle.
- Convert one metric unit to another (e.g. grams to kilograms); read and interpret scales on a range of measuring instruments.
- Compare two simple distributions using the range and one of the mode, median or mean.
- Understand and use the probability scale from 0 to 1; find and justify probabilities based on equally likely outcomes in simple contexts.
- Solve word problems and investigate in a range of contexts, explaining and justifying methods and conclusions.
