Learning Objectives:
 Use the vocabulary of probability in interpreting results involving uncertainty and prediction
 Know that is the probability of an event occurring is p, then the probability of it not occurring
is 1-p
 Find and record all possible mutually exclusive outcomes for combined events using diagrams
and tables
 Identify all mutually exclusive outcomes of an experiment
 Know that the sum of probabilities of all mutually exclusive outcomes is 1, and use this when
solving problems
 Estimate probabilities from experimental data
 Understand that if an experiment is repeated, there may be, and usually will be, different
outcomes
 Compare experimental and theoretical probabilities in a range of contexts
Key Vocabulary:

NC Programme of Study:
Ref2dk: Use angle properties of triangles; understand congruence, recognising when 2 triangles
are congruent. Use 2D representation of 3D shapes and analyse 3D shapes through 2D projections
and cross-sections, including plan and elevation.
Ref3abc: Understand that rotation are specified by a centre and an angle; use right angles,
fractions of turn or degrees to measure the angle of rotation; understand that reflections are
specified by a mirror line, translations by a distance and direction, and enlargements by a centre
and positive scale factor. Recognise and visualise rotations, reflections and translations;
recognise that these transformations preserve length and angle.
Learning Objectives:
 Understand congruence
 Transform 2D shapes by combinations of translations, rotations and reflections, on paper and
using ICT
 Know that translations, rotations and reflections preserve length and angle and map objects on
to congruent images
 Understand and use the language and notation associated with enlargement
 Enlarge 2D shapes given a centre of enlargement and a whole number scale factor, on paper
and using ICT
 Identify the scale factor of an enlargement as the ratio of the lengths of any 2 corresponding
line segments
 Use and interpret maps and scale drawings
Key Vocabulary:
REFLECTION ROTATION TRANSLATION
ENLARGEMENT
CONGRUENCE
TESSELLATION PLAN
ELEVATION
