At St George's, we follow a Maths Mastery approach, which means that we will always use what we already know to make connections in our new maths learning. In Year 1, this involves lots of fun activities, giving the children the chance to practically explore.


Autumn 1




Composition of numbers: multiples of ten up to 100



 Composition of numbers: 20-100

Children will explore multiples of ten, including counting in tens to 100; apply number facts within ten to addition and subtraction for multiples of ten. 

Children will build on multiples of ten, by introducing non-zero values in the ones place; and apply the partitioning structure to these two-digit numbers, decomposing them into tens and ones. 

Teaching point 1: One ten is equivalent to ten ones. 

Teaching point 2: Multiples of ten can be represented using their names or using numerals. We can count in multiples of ten.

Teaching point 3: Knowledge of the 0–10 number line can be used to estimate the position of multiples of ten on a 0–100 number line.

Teaching point 4: Adding ten to a multiple of ten gives the next multiple of ten; subtracting ten from a multiple of ten gives the previous multiple of ten.

Teaching point 5: Known facts for the numbers within ten can be used to add and subtract in multiples of ten by unitising.


Teaching point 1: There is a set counting sequence for counting to 100 and beyond.

Teaching point 2: Objects can be counted efficiently by making groups of ten. The digits in the numbers 20–99 tell us about their value.

Teaching point 3: Each number on the 0–100 number line has a unique position.

Teaching point 4: The relative size of two two-digit numbers can be determined by first examining the tens digits and then, if necessary, examining the ones digits, with reference to the cardinal or ordinal value of the numbers.

Teaching point 5: Each two-digit number can be partitioned into a tens part and a ones part.

Teaching point 6: The tens and ones structure of two-digit numbers can be used to support additive calculation.

Daily Counting

It is essential that children practise their counting skills daily.
