Welcome to our Maths webpage!

At Harrington Hill, we aim to support all children to become confident and creative mathematicians, who choose to challenge themselves at every opportunity.    Here you will find information about the maths curriculum at Harrington Hill, as well as useful links and updates about maths learning at our school.  If you are a parent or carer, interested in maths and would like to be involved in any maths-related events planned for this year, please do get in touch.  I hope you enjoy exploring our page.

Maths Curriculum

At Harrington Hill, we follow the National Curriculum for maths.  The program of study aims to ensure that all pupils:

  • Become fluent in the fundamentals of mathematics
  • Reason mathematically by following a line of enquiry
  • Can solve problems by applying their mathematics to a variety of routine and non-routine problems.

Please see the documents attached below for more information about the objectives that are covered in each year group:


Primary Maths Challenge regional heats

A huge well done to Amandeep, Mustafa and Omer from year 5, who recently competed in the Primary Maths Challenge regional heats, competing against 115 schools across London.  It was a tough competition and we were extremely proud of the teamwork and resilience which they showed throughout the competition.  They were a credit to Harrington Hill.  A huge thank you also goes to Miss Ozdemir who has helped them prepare for the competition

Lord Mayor's 'Count on us' Primary Challenge

Some children from year 4 and 5 have been taking part in a puzzle club in preparation for the Lord Mayor's 'Count on us' Primary Challenge.  ‘Count on Us’ is the Mayor’s Fund for London’s numeracy programme.  They work with schools to help young Londoners reach greater attainment levels in numeracy.  The programme aims to make maths fun and improve confidence around learning as well as improving academic attainment.  They have their first regional heat on the 23rd March.  We wish them all the best of luck!  

Maths Week 2018

In Harrington Hill Primary School, we all took part in a range of maths related activities from Nursery all the way to Year 6.  All year groups looked at how maths is all around us and every subject (literacy, science, art, design and technology) was linked to maths.  We realised how important and amazing maths is!  During the week, we had a visit from Captain Richard Morgan who had gotten lost on his 'Good Ship Mathematics'.  Using our reasoning and problem solving skills, each class was given a challenge which they had to investigate in order to help Captain Richard Morgan get home.  We finished off the week with a maths fancy dress day.  It was a great success and everyone had lots of fun!


Ocean Maths Workshops

In Harrington Hill, we have been successfully running our Ocean Maths workshops for the second year running.  Ocean Maths is a maths project which involves helping parents to support their children with maths homework.  The parents are all invited to a workshop led by the class teacher and the maths lead teacher.  At the workshop, they work alongside their children to share strategies for maths operations and investigations. So far this year we have carried out workshops on place value, addition and subtraction strategies and multiplication and division strategies.  If there is an area of maths that you would like support with, please let us know and we will endeavor to include it in our next  workshop, which will be held next term.  Thank you to all the parents who participated!

Our Mathematician of the month - Leonardo Da Vinci

Leonardo Da Vinci is probably best known as the famous artist who painted the 'Mona Lisa'.  However, he wasn't just a great artist, Da Vinci was also a sculptor, an architect, a poet, a composer, a scientist, an inventor and a MATHEMATICIAN! Wow! It's hard to believe that one man could possibly have that many talents.  Leonardo Da Vinci was a genius and perhaps one of the most remarkable people that has ever lived and believe it or not he never went to school!  Instead he was taught reading, writing and maths at home.  Watch the video below to find out more about his life and achievements:
Born on April 15, 1452, in Vinci, Italy, Leonardo da Vinci was concerned with the laws of science and nature, which greatly informed his work as a painter, sculptor ...

In the video, we learnt about a famous drawing of Leonardo Da Vinci's called 'The Vitruvian Man'.  The Vitruvian man describes the relationship between proportions of the human body and geometry.  He thought that the length of your arm span is equal to your height.  Do you think he is right?  Why not try and measure your own arm span and height at home and prove him right or wrong.  Let us know how you get on!


How to help your child with their times tables


The quick recall of multiplication and division facts (times tables) is essential for all children.  The ability to recall these facts quickly enables children to answer related questions with ease.  According to the National Curriculum the expectation of times tables in each year group is as follows:

Year 1: Counting in multiples of 2, 5 and 10

Year 2: 2x, 5x and 10x and the corresponding division facts

Year 3: 3x, 4x and 8x and the corresponding division facts

Year 4 Know and recall multiplication facts up to 12 x 12 and corresponding division facts

Year 5: Recall quickly multiplication facts to 12 x 12 and use them to multiply pairs of multiples of 10 and 100 e.g. 20 x 300 = 6,000

Year 6: Use knowledge of multiplication facts to derive quickly squares of numbers to 12 x 12 and the corresponding squares of multiples of 10.


We often get asked at parent's evening, what can be done to help children at home with their maths - learning times tables is a brilliant way of helping your child and it really can make a huge difference.  Below is a booklet with ideas to help you support your child with their times tables, it includes some useful strategies, games and links to websites.  We hope you find it useful!




Maths in the world around us!
Take a look around your home, school or outside environment and you'll quickly come to notice that numbers are everywhere.  This month, we will look at using maths during a visit to our local supermarket.  Grocery shopping requires a broad range of maths knowledge from addition, subtraction, multiplication to estimation and percentages.  Below are some activities you could do while on a trip to the supermarket:
  • Best buys - what is the cheapest item they can find in a particular section? Or the most expensive?  Find the cost of different sized cans of baked beans and record their weight. Which is the best value? Why?
  • Give children a list of items they need to shop for.  Can they calculate the total cost?  Ask them to calculate the change from a given amount of money
  • Rounding Receipts - round receipts to the nearest £1 or 50p
  • Weighing fruit and vegetables
  • Calculate 1/2 price discounts or % discounts

Maths Fact of the Month
 If you were to count to a million by ones non-stop, it would take you about 12 days.  If you were to count to a billion by ones non-stop, it would take you about 32 years! Wow!!
