 Maths Mastery at Blackwater







 Problem solving




7th March 2018







We had a really productive day with Shelley Beckerleg of Devon and Cornwall Maths Hub. 
In the morning we looked at our learning walls which we have been developing to showcase our approaches to maths teaching and learning.  Take a look when you are in school to see the learning journey throughout the week. It will give you a snap shot of what your children are learning in maths in terms of fluency, reasoning and problem solving. If you have any questions about maths in school then please pop in to see me in Class 2. I'm always happy to talk about maths! 



Countdown winners: Ruby, Tizzie, Jake R, William R, Savanna, Niamh – prizes to be given in assembly!

Week beginning 05/03/18:




2, 5, 7, 9, 25, 75




75 x 9 = 675 + 4 = 679

7 - 5 = 2

2 + 2 = 4                      








Countdown winners: Well done Niamh, Senan T, Ruby, Freya, Marlie, Lucy, Luca T, Jake R and William R

This policy aims to develop, model and explain core understandings and mathematical principles and progression to ensure consistency in the teaching and learning of mathematics in our schools.

The focus of this policy is the calculation of the four mathematical operations with an emphasis on written strategies to clarify processes and understanding. Mental strategies are discretely taught and linked to written strategies.


The overall aims of this policy are that, when children leave primary school they:


  • have a secure knowledge of number facts and a good understanding of the four operations.
  • be fluent in the recall and application of number facts.
  • be fluent in written and mental calculation methods.
  • be able to explain the best strategy to use.
  • be able to use jottings and drawings to aid calculation and to explain and justify answers.
  • understand number by using estimating before calculating and checking systematically using the inverse.
  • Apply understanding by breaking problems down into a series of simpler steps, confidently using the four operations in the process.
  • be able to identify when a calculator is the best tool for the task and use this primarily as a way of checking rather than simply a way of calculating.
  • be able to explain their strategies to calculate and using spoken language, give justification, argument or proof of their reasoning.

National Curriculum Introduction

The national curriculum for mathematics aims to ensure that all pupils: • 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 • reason mathematically by following a line of enquiry, conjecturing relationships and generalisations, and developing an argument, justification or proof using mathematical language • can solve problems by applying their mathematics to a variety of routine and non-routine problems with increasing sophistication, including breaking down problems into a series of simpler steps and persevering in seeking solutions.’ (National curriculum page 3)  


At Blackwater Primary School, we believe everyone can achieve in maths.

We encourage a positive attitude in our children where mistakes are seen as opportunities for learning, encouraging them in the belief that by being resilient they can succeed. At Blackwater, we wish to dispel the misconception that people are born with or without a gift for maths and that with aspiration; the sky is the limit for all.

We wish to enable our children to achieve mastery in mathematics by providing learning opportunities to develop:

* fluency in understanding and manipulation of number and calculation methods.

* the ability to reason mathematically

* the ability to problem solve in maths and across the curriculum.

We aim to provide challenging and nurturing learning environment where mistakes are viewed as opportunities for new neurological pathways to be formed. We set high expectations and levels of challenge but plan and deliver learning opportunities that are accessible for all. We create interesting contexts where children can apply their maths learning across the curriculum.

We create a growth mindset maths culture at Blackwater by:

* instilling a ‘can do’ attitude in all of our children

* celebrating achievement in maths in monthly assemblies

* sharing our enthusiasm for mathematics

* using concrete materials throughout the school to build understanding before moving on to visual and abstract representation of the maths.

* providing opportunities for meaningful practice involving variety and challenge to develop fluency

* encouraging reasoning through emphasis on the ‘how’ and ‘why’.

* providing accessible yet challenging problem solving activities to enable children to make connections between different areas of mathematics and the wider curriculum.

* providing timely interventions and pre-teaching to enable pupils to access mathematics.

When our children see their achievements, we see them learning to love maths. We enjoy seeing our children inspired by maths in the wider world and engaging with it.

Weekly Countdown Challenges

Each week in school we have two count down challenges.  They are displayed in the entrance hall of the school along with information about our approach to maths at Blackwater.

Children should complete the challenges at home and return their responses to Ms Shuttleworth in Class 2 on Fridays.

Countdown Challenge

Can you make the total?  

Make the total displayed each week with the numbers provided.

You can use any operation you like. Be as creative as you like!

This week's total:  54

This week's numbers:  20  3. 2. 6. 5. 

2.  This is the answer.  What is the question?

We give you the answer and you have to make up possible questions.

e.g.   the answer is 10    

The question could be:  110 - 100.   0.1 x 100.  5 + 5.   1/10 of 100

50 - 40,   345. -  335. and so on........

This week's answer is 15

What is the question?

Winners with the most creative solutions or questions will be featured on the web site, newsletter and awarded a countdown prize at assembly on Mondays.
