Numbers to 20


This unit lays the essential foundations of place value, as children begin to recognise the place value of each digit in a 2-digit number. This is an important skill that children will develop when they add and subtract and begin to work with larger numbers. 

Children will count in 10s and 1s, learning that they can partition 2-digit numbers into tens and ones. They will find the number that is one more or one less than a given number, noticing when tens digit changes and when only the ones digit changes. 

As they become more fluent, they will begin to compare and order numbers to 20 using the < and > signs. 

Maths Fluency 


Children in Year 1 will take part in an additional maths lesson each afternoon which will focus on developing their fluency. During these sessions they will engage in practical activities using a Rekenrek and materials from Numberblocks.  


Maths fluency means that children will be able to use their skills to know the best way to solve a maths problem. It also means developing number sense and being able to use those skills in a variety of contexts.

Most importantly, maths fluency allows learners to understand the relationship between numbers. It means that not only do they get to grips with how they answer something, but they also understand why they’ve reached their answer.
