Year 8 Maths

- Use written methods to multiply up a 3 figure by a 2 figure number and divide by a number up to 12.
- Add and subtract decimals up to 2 decimal places and use knowledge to solve worded/functional questions including questions involving money.
- Use a calculator to solve single operation problems. (Practical/functional problems).
- Understand common factors, multiples, primes and square numbers.
- Calculate unitary fractions of an amount.
- Understand the rules and notation of algebra.
- Begin to use simple formulae expressed in words.
- Solve single operation equations by using inverse operations. i.e.( x – 5 = 7)
- Substitute into simple expressions.
- Use and interpret co-ordinates in 4 quadrants. Draw and describe horizontal and vertical lines of the form x = 2 and y = -3
- Simplify expressions by collecting like terms. (only positive)
- Continue the sequence and describe the pattern of a linear sequence.
- Convert miles to kilometres and pounds to kilograms. Answer functional problems using the conversions.
- Measure and draw angles using a protractor. Draw circles using a pair of compasses given the radius or diameter. Draw basic scale drawings of room plans. i.e. (ground floor room or house plan)
- Reflect shapes and describe the reflections in horizontal and vertical lines
- Understand the terms the terms edges, faces and vertices.
- Calculate the area of a triangle.
- Use mode and range to compare 2 distributions of data.
- Design a grouped tally chart to collect discrete data .i.e. (Marks scored in a test)
- Draw and interpret dual bar charts.
- Use basic Venn diagrams.
- Interpret 2 way tables and complete pre drawn 2 way tables.
- Calculate basic probabilities written as a fraction.
- Round numbers to the nearest integer, to a given power of ten, to one significant figure and to one or two decimal places; estimate answers to one- stage calculations including problems involving money and measurement.
- Use the term cube; recall the cubes of 2, 3, 4, 5, and 10; use index notation for simple integer powers.
- Understand equivalent fractions, simplifying a fraction (including mixed numbers) by cancelling all common factors; multiply a fraction by an integer or a unit fraction.
- Use the equivalence between fractions, decimals and percentages in context; solve simple percentage problems including increase and decrease.
- Express one quantity as a fraction or percentage of another.
- Use the four operations with positive and negative integers.
- Solve problems involving substitution of positive numbers into simple algebraic formulas.
- Solve simple linear equations in which the unknown appears on either side of the equation.
- Manipulate algebraic expressions by collecting like terms.
- Use tables to plot graphs of linear functions given explicitly.
- Construct triangles using a ruler and protractor only given information about their sides and angles; use a straight edge and compasses to construct triangles with given sides including equilateral triangles.
- Use and interpret maps and scale drawings, including four-figure grid references and estimating distances and areas; use bearings to specify direction.
- Classify quadrilaterals by their geometric properties.
- Explore the geometry of cuboids (including cubes) and shapes made from cuboids; find the volumes of cuboids, recalling the formula; draw and interpret the net of a cuboid.
- Understand that rotations are specified by a centre and an angle; complete the rotation symmetry of 2-D shapes; measure the angle of rotation using right angles and simple fractions of a turn.
- List all outcomes for single events, and for two successive events, in a systematic way; find probabilities. Use the fact that the probability of not happening is 1 – probability of happening.
- Use and interpret the statistical measures mode, median, mean and range for discrete and continuous data, including comparing distributions.
- Construct and interpret pie charts.
