At St. George's we use a mastery approach to teaching Mathematics which is rich in contextual understanding and uses many visual and concrete resources to ensure all children comprehend.

Autumn 1 - This half-term we are focusing on improving our number (place value), addition and subtraction knowledge.

Most of us shall be studying:

Spine 1: Number, Addition and Subtraction - Topic 1.26 and 1.27

We shall begin by exploring the composition of six-digit, whole-thousand numbers, using the partitioning structure and apply knowledge and strategies to larger numbers by unitising in 1,000s, as well as column methods and rounding.

Teaching points

  • Teaching point 1: Understanding of numbers composed of hundred thousands, ten thousands and one thousands can be supported by making links to numbers composed of hundreds, tens and ones.


  • Teaching point 2: Multiples of 1,000 up to 1,000,000 can be placed in the linear number system by drawing on knowledge of the place of numbers up to 1,000 in the linear number system.


  • Teaching point 3: Numbers can be ordered and compared using knowledge of their composition and of their place in the linear number system.


  • Teaching point 4: Calculation approaches for numbers up to 1,000 can be applied to multiples of 1,000 up to 1,000,000.


  • Teaching point 5: Numbers can be rounded to simplify calculations or to indicate approximate sizes.


  • Teaching point 6: Known patterns can be used to divide 10,000 and 100,000 into two, four and five equal parts. These units are commonly used in graphing and measures

We shall  also be introducing the children to negative numbers, making links to everyday contexts and exploring addition and subtraction below zero and across zero.

Teaching points:

  • Teaching point 1: Positive and negative numbers can be used to represent change.
  • Teaching point 2: Our number system includes numbers that are less than zero; these are negative numbers. Numbers greater than zero are positive numbers.
  • Teaching point 3: The negative/minus symbol (−) is placed before a numeral to indicate that the value is a negative number.
  • Teaching point 4: Negative numbers can be shown on horizontal scales; numbers to the left of zero are negative (less than zero) and numbers to the right of zero are positive (greater than zero). The larger the value of the numeral after the negative/minus symbol, the further the number is from zero.
  • Teaching point 5: Knowledge of the positions of positive and negative numbers in the number system can be used to calculate intervals across zero.
  • Teaching point 6: Negative numbers are used in coordinate and graphing contexts.

Mathletics Homework

Please continue to complete Mathletics work for homework weekly. This homework links with the current learning happening in class.

You can also challenge yourself with the live mathletics section of the website. If you need a reminder of your username and password, please email me on



Children are expected to know their timestables to 12 x 12 and associated division facts fluently. Each week we complete a varied table practise test to increase speed. After the test, Children are asked to identify which timestable they need to work on independently at home. Please see games section for timestables online games to support fluency.
