33. Statistics
Present data in these graphs and tables and solve problems:
Favourite Colour
1) How many children were asked to vote for their favourite colour?
Bar Charts
2a) How many more children chose cheese and onion as their favourite crisps than ready
salted?

35. Time Graphs
Time graphs show the changing of data over time. These often take the form of line graphs
but can also be a bar chart.
Number of Children Who Have a School Meal
4) How many school meals were served during the week?

London 10:20 11:30 16:40
Derby 12:20 18:00
Sheffield 12:40 13:10 18:30
Hull 13:20 13:55 19:15
Newcastle 14:25 14:40
6) Which train takes the least time to get from London to Hull?
Pie Charts
Pie charts show data by dividing a circle to represent the different proportions of the data.
A class of children chose their favourite flavour of crisps. Here is a pie chart of the results.
Salt and Vinegar
Cheese and Onion
In questions about pie charts children have to use the proportion of
the pie to work out answers.
In this pie chart, 20 children are asked how they travel to school.
7) Estimate how many children travelled by bus.
8a) The mean of a set of data is equivalent to sharing the data out .
b) If 4 test scores are 3, 5, 6, 8, the mean is found by adding the data (3 + 5 + 6 + 8 = )
and then sharing between the 4 scores by dividing by 4 ( ÷4= ).
c) What is the mean of 15, 17, 20, 24, 24?

Some vocabulary is also described within the booklet. Fill in the missing information:
Vocabulary Meaning
Flat shapes with no thickness. In theory a 2D shape cannot be picked up,
2D shapes but in practice shapes made of paper are counted as 2D.
(A list of shapes is included in the section on shape.)
A shape with 3 dimensions that can be picked up.
3D shapes

Algebra
Analogue
Area The amount of space taken up by a shape.
or division.
Capacity
The answer is the same no matter which way the calculation is
Commutativity
completed: e.g. 2 + 4 = 4 + 2 or 2 × 4 = 4 × 2.
A number that has more than 2 factors.
(1 is not a composite number because it only has 1 factor.)
Cube number The result of multiplying a whole number by itself twice: e.g. 2 × 2 × 2 = 8
Denominator
A single symbol used to make a numeral: 7
(All numbers are made from the ten digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0.)
Digital A clock using digits to tell the time.
Discrete
A statement where the value of each mathematical expression is equal:
e.g. 3 + 4 = 7
Equivalent A fraction which has the same value but is divided into a different
1 2
fraction number of parts: e.g. 2 = 4
A factor of a number is a number into which the number can be divided
Factor
with no remainders: e.g. the factors of 8 are 1, 2, 4, and 8.
Factor pairs are 2 factors that are multiplied together to make the
number: e.g. the factor pairs of 8 are 1 and 8, 2 and 4.
A number expressed as the number of parts into which the whole has
Fraction 3
been divided: e.g 4 represents 3 parts out of 4.

38. 9
A fraction where the numerator is larger than the denominator: e.g 2
A whole number with no parts: e.g. 5, 18, 109.
A whole number with no fraction or decimal part: e.g. 6 or 57.
An inverse operation is the opposite or reverse of an operation: e.g. the
Inverse
inverse of 6 – 4 = 2 is 2 + 4 = 6 or the inverse of 6 ÷ 3 = 2 is 2 × 3 = 6.
Often known as weight – how much matter is in an object.

Mixed number A whole number and a proper fraction: e.g. 4 2
A symbol, symbols, word or words that stand for a number: 37 or thirty-

seven.
Numerator The top part of a fraction.
Perimeter
Place value The value of each digit in any number: In 27 the 2 represents 2 tens.
A 2D shape with any number of sides.
Prime factor A factor which is a prime number: e.g. 3 is a prime factor of 12.
Prime Number

Proper fraction A fraction where the numerator is smaller than the denominator: e.g 2
A quarter of the space represented by coordinates, bordered by
the x and y axes.
A shape with all angles as right angles
Rectilinear
(the right angle can be inside or outside the shape).
The mathematical relationship between different measurements or
Scale
number of objects.
Square number The result of multiplying a whole number by itself: e.g. 2 × 2 = 4
Multiplying 2 numbers by a number and adding, gives the same answer
as multiplying the sum of the 2 numbers by the other number:
e.g. 4 × (3 + 2) = 4 × 3 + 4 × 2.
The movement of a shape without rotation or reflection.
Volume
Mass is measured by how much something weighs, but this can change
in different locations.
