Course Content
Number
-
Identify and use: • natural numbers • integers (positive, zero and negative) • prime numbers • square numbers • cube numbers • common factors • common multiples • rational and irrational numbers • reciprocals.
-
Example tasks include: • convert between numbers and words, e.g. six billion is 6000000000 10007 is ten thousand and seven • express 72 as a product of its prime factors
-
• find the highest common factor (HCF) of two numbers • find the lowest common multiple (LCM) of two numbers.
-
Understand and use set language, notation and Venn diagrams to describe sets and represent relationships between sets.
-
Venn diagrams are limited to two or three sets. The following set notation will be used: • n(A) Number of elements in set A • ∈ “… is an element of …” • ∉ “… is not an element of …” • A′ Complement of set A
-
• ∅ The empty set • Universal set • A ⊆ B A is a subset of B • A ⊈ B A is not a subset of B • A ∪ B Union of A and B • A ∩ B Intersection of A and B.
-
Example definition of sets: A = {x: x is a natural number} B = {(x, y): y = mx + c} C = {x: a ⩽ x ⩽ b}
-
Calculate with the following: • squares • square roots • cubes • cube roots • other powers and roots of numbers.
-
Includes recall of squares and their corresponding roots from 1 to 15, and recall of cubes and their corresponding roots of 1, 2, 3, 4, 5 and 10, e.g.: • Write down the value of (169)^1/2 • Work out 5^2x^3(8)^1/3 .
-
1 Use the language and notation of the following in appropriate contexts: • proper fractions • improper fractions • mixed numbers • decimals • percentages.
-
2 Recognise equivalence and convert between these forms.
-
Candidates are expected to be able to write fractions in their simplest form. Recurring decimal notation is required, e.g. • 0.1 7 = 1777…. • 0.123 =0.1232323…• 0.123 =0.123123…
-
Includes converting between recurring decimals and fractions and vice versa, e.g. write 0.17 as a fraction.
-
Order quantities by magnitude and demonstrate familiarity with the symbols =, ≠, >, < , ⩾ and ⩽.
-
Use the four operations for calculations with integers, fractions and decimals, including correct ordering of operations and use of brackets.
-
Includes: • negative numbers • improper fractions • mixed numbers • practical situations, e.g. temperature changes.
-
Understand and use indices (positive, zero, negative, and fractional).
-
Understand and use the rules of indices.
-
• find the value of 7^ –2, e.g. find the value of 2^–3 × 2^4 , (2^3 )^2 , 2^3 ÷ 2^4
-
Use the standard form A × 10n where n is a positive or negative integer and 1 ⩽ A < 10.
-
Convert numbers into and out of standard form.
-
Calculate with values in standard form.
-
Round values to a specified degree of accuracy
-
Make estimates for calculations involving numbers, quantities and measurements.
-
Round answers to a reasonable degree of accuracy in the context of a given problem.
-
Includes decimal places and significant figures. e.g. write 5764 correct to the nearest thousand. e.g. by writing each number correct to 1 significant figure, estimate the value of 41.3/9.79*0.765
-
Give upper and lower bounds for data rounded to a specified accuracy.
-
Find upper and lower bounds of the results of calculations which have used data rounded to a specified accuracy
-
e.g. write down the upper bound of a length measured correct to the nearest metre. Example calculations include:
-
• calculate the upper bound of the perimeter or the area of a rectangle given dimensions measured to the nearest centimetre • find the lower bound of the speed given rounded values of distance and time
-
Understand and use ratio and proportion to: • give ratios in their simplest form • divide a quantity in a given ratio • use proportional reasoning and ratios in context.
-
e.g. 20:30:40 in its simplest form is 2:3:4. e.g. adapt recipes; use map scales; determine best value.
-
Use common measures of rate.
-
e.g. calculate with: • hourly rates of pay • exchange rates between currencies • flow rates • fuel consumption
-
Apply other measures of rate.
-
e.g. calculate with: • pressure • density • population density. Required formulas will be given in the question.
-
Solve problems involving average speed.
-
Knowledge of speed/distance/time formula is required. e.g. A cyclist travels 45km in 3 hours 45 minutes. What is their average speed? Notation used will be, e.g. m/s (metres per second), g/cm3 (grams per cubic centimetre).
-
Calculate a given percentage of a quantity
-
Express one quantity as a percentage of another
-
Calculate percentage increase or decrease.
-
Calculate with simple and compound interest.
-
Problems may include repeated percentage change. Formulas are not given.
-
Calculate using reverse percentages.
-
e.g. find the cost price given the selling price and the percentage profit. Percentage calculations may include: • deposit • discount • profit and loss (as an amount or a percentage) • earnings • percentages over 100%.
-
Use a calculator efficiently
-
e.g. know not to round values within a calculation and to only round the final answer.
-
Enter values appropriately on a calculator.
-
e.g. enter 2 hours 30 minutes as 2.5 hours or 2° 30’ 0’’.
-
Interpret the calculator display appropriately.
-
e.g. in money 4.8 means $4.80; in time 3.25 means 3 hours 15 minutes.
-
Calculate with time: seconds (s), minutes (min), hours (h), days, weeks, months, years, including the relationship between units.
-
1 year = 365 days
-
Calculate times in terms of the 24-hour and 12-hour clock
-
In the 24-hour clock, for example, 3.15 a.m. will be denoted by 0315 and 3.15 p.m. by 1515
-
Includes problems involving time zones, local times and time differences.
-
Calculate with money.
-
Convert from one currency to another.
-
Use exponential growth and decay.
-
e.g. depreciation, population change. Knowledge of e is not required.
