A 6-Week Plan for Beating the Summer Maths Slide for KS1 and KS2 Children
Mathnasium's education specialists share a six-week plan to keep KS1 and KS2 maths skills sharp over summer and ready for September.
During the first half-term of primary school, children begin their new year group maths while teachers check their baseline understanding to see where they may need more practice.
What this looks like can vary considerably from Reception through Year 6, and schools can organise their maths curriculum differently. Parents may therefore have questions about which skills their child is developing, what early assessments can show and what deserves attention before half-term.
Our team of expert maths educators in Clapham will explain what children may be learning at different stages, what teachers can assess and what you can do based on what you notice during the first half-term.
The first half-term highlights how your child is managing the maths for their new year group while leaving plenty of time to address any areas that may need more attention.
Several factors can explain what makes this period particularly relevant to your child’s maths progress:
New year-group maths draws on previous knowledge. According to Department for Education guidance for Years 1 to 6, mathematical concepts connect across year groups, with knowledge gained at one stage supporting more advanced work. Place value, for example, supports calculations with increasingly large numbers, while multiplication facts connect with division and fractions.
Teachers gather evidence about current understanding. Classwork, questions and assessments can show how children are using the maths they have already learned. Some schools also use standardised autumn assessments, including NFER assessments, which can provide a baseline for monitoring attainment and progress during the school year.
Children can consolidate earlier learning. Schools have flexibility over how they sequence content within each key stage, while the National Curriculum in England sets out the content children should learn. It also states that children who are not sufficiently fluent with earlier material should consolidate their understanding through additional practice before moving on.
By half-term, you may have more information from classwork, homework or assessment results about how your child is getting on, which gives you something concrete to discuss with their teacher and an area to keep an eye on as the term continues.

Primary maths develops significantly from Reception to Year 6 as children encounter new concepts and build on what they already know.
Reception follows the Early Years Foundation Stage (EYFS), which sets the learning and development requirements for this age group, while Years 1 to 6 gradually introduce more advanced number work, calculations and mathematical reasoning.
Let’s look at some of the concepts your child may encounter at different points in primary school.
Reception and Year 1 develop children’s understanding of numbers, quantities and the relationships between them.
In Reception, children develop a deep understanding of numbers to 10, including how numbers are composed and related, before Year 1 introduces more formal number work and calculations.
Your child may:
count objects and connect quantities with numerals
recognise, order and compare numbers
combine smaller quantities to make larger ones
notice and continue number or shape patterns
use objects, pictures and number lines to represent mathematical ideas
Reception children use these early number relationships to explore addition and subtraction. By Year 1, children work with number bonds and mathematical statements involving both operations.

Children in Years 2 and 3 extend their understanding of place value as they use larger numbers and a wider range of calculations. In Year 2, children work with two-digit numbers within 100, while Year 3 includes three-digit numbers up to 1,000.
At this stage, children may:
read, write, compare and order numbers
use place value to partition numbers
develop addition and subtraction methods
build multiplication and division knowledge
apply number skills to mathematical and practical problems
Year 3 also includes formal written methods for addition and subtraction. Schools may introduce them at different points during the year, so your child may not encounter them during the first half-term.

By Years 4 to 6, children tackle more complex calculations and develop their understanding across a broader range of number concepts.
Topics may include:
place value with increasingly large numbers
multiplication and division facts and methods
fractions, decimals and percentages
multi-step calculations and problems
mathematical relationships and explanations of methods
Years 5 and 6 also develop more advanced connections between fractions, decimals and percentages, while Year 6 introduces formal work with ratio, proportion and simple algebraic relationships.

Teachers assess your child’s maths throughout the first half-term in several ways. They can gather evidence during lessons through questions, observations, classwork and short tasks, rather than relying on one type of assessment.
The main areas they look at include:
| Area | What teachers look for |
| Number skills | Recall and use of number facts, place value and number relationships appropriate for the year group |
| Calculation | Choice and use of suitable methods for addition, subtraction, multiplication or division |
| Mathematical understanding | Your child’s grasp of what numbers, symbols and operations represent in a calculation or problem |
| Problem-solving | Whether your child identifies what a problem requires and applies suitable maths in less familiar situations |
| Reasoning | How your child connects mathematical ideas, justifies an answer and explains their thinking |
For Years 1 to 6, there is no single statutory maths assessment that every child takes during the first half-term. The statutory maths checks and tests that apply to specific year groups take place later in the school year.
For example, children in Year 4 take the multiplication tables check in June, while children in Year 6 take the national curriculum tests in May.
However, Reception has its own statutory assessment at the start of the school year. The Reception Baseline Assessment (RBA) takes place within the first 6 weeks of a child joining Reception and provides a starting point for measuring progress through primary school.
It includes two components:
Mathematics, which covers number, calculation, pattern and measure
Literacy, communication and language
Children complete the assessment individually with a practitioner through short, interactive tasks. It usually takes less than 20 minutes and may involve verbal responses, practical resources and a touchscreen.

During the first half-term, you can support your child by staying informed about the maths they are learning and using that information to guide what you do at home.
The Education Endowment Foundation (EEF) recommends connecting maths at home with classroom learning and choosing activities that suit your child’s age. Based on that guidance, we suggest a few practical steps for these first weeks:
Check what your child is learning in maths. Look at homework, school updates or curriculum information to see which topics they have covered since the start of term. This can give you a clear place to start if you want to practise together at home.
Revisit recent maths in a way that suits their age. Younger children can practise counting, sharing, measuring or recognising shapes through games and everyday activities. Older primary children can return to examples from class, practise number facts or try similar questions from topics they have already covered.
Follow the method your child is learning at school. If the method looks unfamiliar, have your child show you an example from class or check any guidance the school has provided. You can then work through another question together using the same approach.
Get more context from your child’s teacher. Comments on classwork or conversations with their teacher can help you understand whether a possible difficulty you notice at home also appears during lessons. You can also find out which areas would be most useful to practise at this point in the year.
If the same challenges continue across different tasks or situations, a more targeted assessment can help identify the skill or earlier knowledge behind it.
At Mathnasium, our diagnostic assessment identifies what your child already knows and where gaps remain, then guides their customised learning plan.

At Mathnasium, we go far beyond traditional teaching methods to help children understand and develop a love for maths.
Mathnasium is a maths-only learning centre dedicated to helping students of all skill levels excel in maths.
Whether your child needs help with something they have found difficult during the first half-term, has gaps from earlier learning or is ready for more challenge, we can support them.
We deliver that support through the Mathnasium Method™, our proprietary teaching approach designed to help children build maths mastery through deep understanding. Our approach includes:
Assessment and customised learning plans. Every child begins their Mathnasium journey with a diagnostic assessment that identifies what they already know and where gaps remain. We use the results to create a bespoke learning plan that addresses those gaps, builds on existing knowledge and provides greater challenge where appropriate.
Teaching for understanding. Our specially trained instructors teach children how and why maths works rather than simply asking them to memorise methods. They use mental, verbal, visual, tactile and written techniques to explain concepts in different ways and develop mathematical thinking.
Face-to-face instruction. Children work face-to-face with specially trained instructors and follow their own learning plan at a pace that suits them. Families can choose between in-centre and live online instruction, depending on the options available through their centre.
Continued progress and confidence. We monitor your child’s progress as they work through their learning plan and continue building from what they understand. As maths begins to make more sense, children can become more comfortable approaching new problems and more confident in their own mathematical thinking.
The results show what this approach can achieve:
94% of parents report an improvement in their child's maths skills and understanding
93% of parents report their child's improved attitude towards maths after attending Mathnasium
