 # Year 7 Maths • Identify multiples and factors, including finding all factor pairs of a number, and common factors of two numbers
• Know and use the vocabulary of prime numbers, prime factors and composite (non-prime) numbers
• Establish whether a number up to 100 is prime and recall prime numbers up to 19
• Recognise and use square numbers and cube numbers, and the notation for squared (²) and cubed (³)
• Read, write, order and compare numbers to at least 1 000 000 and determine the value of each digit
• Read Roman numerals to 1000 (M) and recognise years written in Roman numerals
• Interpret negative numbers in context, count forwards and backwards with positive and negative whole numbers, including through zero
• Add and subtract numbers mentally with increasingly large numbers
• Add and subtract whole numbers with more than 4 digits, including using formal written methods (columnar addition and subtraction)
• Solve addition and subtraction multi-step problems in contexts, deciding which operations and methods to use and why
• Multiply and divide numbers mentally drawing upon known facts
• Multiply and divide whole numbers and those involving decimals by 10, 100 and 1000
• Multiply numbers up to 4 digits by a one- or two-digit number using a formal written method, including long multiplication for two-digit numbers
• Divide numbers up to 4 digits by a one-digit number using the formal written method of short division and interpret remainders appropriately for the context
• Solve problems involving multiplication and division including using their knowledge of factors and multiples, squares and cubes
• Solve problems involving multiplication and division, including scaling by simple fractions and problems involving simple rates
• Solve problems involving addition, subtraction, multiplication and division and a combination of these, including understanding the meaning of the equals sign
• Use the properties of rectangles to deduce related facts and find missing lengths and angles
• Distinguish between regular and irregular polygons based on reasoning about equal sides and angles
• Identify 3-D shapes, including cubes and other cuboids, from 2-D representations
• Solve problems involving converting between units of time
• Complete, read and interpret information in tables, including timetables
• Compare and order fractions whose denominators are all multiples of the same number
• Identify, name and write equivalent fractions of a given fraction, represented visually, including tenths and hundredths
• Recognise and use thousandths and relate them to tenths, hundredths and decimal equivalents
• Read and write decimal numbers as fractions [for example, 0.71 = 71/100]
• Read, write, order and compare numbers with up to three decimal places
• Recognise the per cent symbol (%) and understand that per cent relates to ‘number of parts per hundred’, and write percentages as a fraction with denominator 100, and as a decimal
• Count forwards or backwards in steps of powers of 10 for any given number up to 1 000 000
• Convert between different units of metric measure (for example, kilometre and metre; centimetre and metre; centimetre and millimetre; gram and kilogram; litre and millilitre)
• Understand and use approximate equivalences between metric units and common imperial units such as inches, pounds and pints
• Use all four operations to solve problems involving measure [for example, length, mass, volume, money] using decimal notation, including scaling
• Know angles are measured in degrees: estimate and compare acute, obtuse and reflex angles
• Draw given angles, and measure them in degrees (°)
• Identify: angles at a point and one whole turn (total 360°); angles at a point on a straight line and 1/2 a turn (total 180°); other multiples of 90°
• Recognise mixed numbers and improper fractions and convert from one form to the other and write mathematical statements > 1 as a mixed number [for example, 2/5 + 4/5 = 6/5 = 1 1/5]
• Add and subtract fractions with the same denominator and denominators that are multiples of the same number
• Multiply proper fractions and mixed numbers by whole numbers, supported by materials and diagrams
• Solve problems which require knowing percentage and decimal equivalents of 1/2, 1/4, 1/5, 2/5, 4/5 and those fractions with a denominator of a multiple of 10 or 25
• Solve problems involving number up to three decimal places
• Measure and calculate the perimeter of composite rectilinear shapes in centimetres and metres
• Calculate and compare the area of rectangles (including squares), and including using standard units, square centimetres (cm²) and square metres (m²) and estimate the area of irregular shapes
• Estimate volume [for example, using 1 cm³ blocks to build cuboids (including cubes)] and capacity [for example, using water]
• Round any number up to 1 000 000 to the nearest 10, 100, 1000, 10 000 and 100 000
• Round decimals with two decimal places to the nearest whole number and to one decimal place
• Use rounding to check answers to calculations and determine, in the context of a problem, levels of accuracy
• Identify, describe and represent the position of a shape following a reflection or translation, using the appropriate language, and know that the shape has not changed
• Solve comparison, sum and difference problems using information presented in a line graph
