National Curriculum
Become fluent in the fundamentals of
mathematics, including through varied and
frequent practice with increasingly complex
problems over time, so that pupils develop
conceptual understanding and the ability to
recall and apply knowledge rapidly and
accurately.

National Curriculum
Reason mathematically by following a line of
enquiry, conjecturing relationships and
generalisations, and developing an
argument, justification or proof using
mathematical language

Reach 100
Choose four different digits from 1−9 and
put one in each box. For example:
This gives four two-digit
numbers: 52,19, 51, 29
In this case their sum is 151.
Can you find four different digits that give
four two-digit numbers which add to a total
of 100?

6 + 4 = 10
10 take away 9 makes 1
1 add 17 is 18

How do these rich tasks contribute to
fluency?
reasoning?

Efficiency
An efficient strategy is one that the student
can carry out easily, keeping track of subproblems and making use of intermediate
results to solve the problem.
© University of Cambridge
Efficiency
Accuracy
depends on careful recording, the
knowledge of basic number combinations
and other important number relationships,
and checking results.
© University of Cambridge
Efficiency
Accuracy
Flexibility
requires the knowledge of more than one
approach and being able to choose
appropriately between them

Procedural &
conceptual fluency
Automaticity
Automaticity with recall

Fluency
Procedural without conceptual
Conceptual without procedural
Computation without meaning
Computation which is slow, effortful
and frustrating
Inability to adapt skills to unfamiliar
contexts
Inability to focus on the bigger picture
when solving problems
Difficulty reconstructing forgotten
knowledge or skills
Difficulty progressing to new or more
complex ideas

Using the same rules is it possible to cross all
the numbers off?

Two types of reasoning
Inductive reasoning
• Can be incorrect
• Can’t be used to ‘prove’
Deductive reasoning
• Follows rules of logic
• Can be used to prove
© University of Cambridge
In a problem:
• Reasoning is necessary when:
• The route through the problem is not clear
• There are some conflicts in what you are
given or know
• There are some things you don’t know
• Theres no structure to what you’re given
• There are different possible solutions
• All of which require mental work….
© University of Cambridge
Reasoning is…
• A critical skill to knowing and doing maths
• Enabling – it allows children to make use of all
the other mathematical skills – it’s the glue that
helps maths to make sense.

Modelling KS1: good 'because'
statements, short chains

Session 2
Problem solving
© University of Cambridge
National Curriculum
Can solve problems by applying their
mathematics to a variety of routine and nonroutine problems with increasing
sophistication, including breaking down
problems into a series of simpler steps and
persevering in seeking solutions
© University of Cambridge
Historically
• learning the content v problem solving
• theory versus practice, reason versus
experience, acquiring knowledge versus
applying knowledge.
• problems seen as vehicles for practicing
applications ie computation procedures are
acquired first and then applied
• problem-based learning

Dominoes – have a play….
Have you got a full set?
How do you know?
Can you arrange them in some way to
convince yourself/others that you have/
haven’t got full set?

• What number knowledge/skills did you
use?
• What mathematical processes did you
use?
• What ‘soft skills’ did you use?

Amy has a box containing ordinary
domino pieces but she does not think it is
a complete set. She has 24 dominoes in
her box and there are 125 spots on them
altogether. Which of her domino pieces
are missing?

Rich tasks….
• combine fluency, problem solving and
mathematical reasoning
• are accessible
• promote success through supporting
thinking at different levels of challenge (low
threshold - high ceiling tasks)
• encourage collaboration and discussion
• use intriguing contexts or intriguing maths
© University of Cambridge
• allow for:
•
•
•
•
learners to pose their own problems,
different methods and different responses
identification of elegant or efficient solutions,
creativity and imaginative application of
knowledge.
• have the potential for revealing patterns or
lead to generalisations or unexpected
results,
• have the potential to reveal underlying
principles or make connections between
areas of mathematics

Purposeful activity
Give the pupils something to do,
not something to learn;
and if the doing is of such a nature
as to demand thinking;
learning naturally results.

“If I ran a school, I’d give all the average
grades to the ones who gave me all the right
answers, for being good parrots. I’d give the
top grades to those who made lots of
mistakes and told me about them and then
told me what they had learned from them.”

Purpose of study
Mathematics is a creative and highly interconnected discipline that has been developed over
centuries, providing the solution to some of
history’s most intriguing problems. It is essential to
everyday life, critical to science, technology and
engineering, and necessary for financial literacy
and most forms of employment. A high-quality
mathematics education therefore provides a
foundation for understanding the world, the ability
to reason mathematically, an appreciation of the
beauty and power of mathematics, and a sense of
enjoyment and curiosity about the subject.

Year 6
Pupils should be taught to:
•use simple formulae
•generate and describe
linear number sequences
•express missing number
problems algebraically
•find pairs of numbers that
satisfy an equation with two
unknowns
•enumerate all possibilities of
combinations of two
variables.
• Pupils should be introduced to
the use of symbols and letters to
represent variables and
unknowns in mathematical
situations that they already
understand, such as:
• missing numbers, lengths,
coordinates and angles,
• formulae in mathematics and
science
• equivalent expressions (for
example, a + b = b + a)
• generalisations of number
patterns
• number puzzles (for example,
what two numbers can add up
to).

The expectation is that the majority of pupils will
move through the programmes of study at broadly
the same pace. However, decisions about when to
progress should always be based on the security
of pupils’ understanding and their readiness to
progress to the next stage. Pupils who grasp
concepts rapidly should be challenged through
being offered rich and sophisticated problems
before any acceleration through new content.
Those who are not sufficiently fluent with earlier
material should consolidate their understanding,
including through additional practice, before
moving on.
Opportunities?
© University of Cambridge
The programmes of study for mathematics
are set out year-by-year for Key Stages 1
and 2. Schools are, however, only required
to teach the relevant programme of study by
the end of the key stage. Within each key
stage, schools therefore have the flexibility
to introduce content earlier or later than set
out in the programme of study.
