# Weights and measurements articles

What your child learns in Nursery maths
Times tables and long division may be a way off, but the basic numeracy skills your child begins to learn in Nursery will lay the foundations for the years ahead.
What are imperial units?
How children learn about imperial units of measurement in primary school, plus metric to imperial conversion tables.
Best maths story books for children
Introduce ratio, pie charts, probability and even simplifying fractions to children with these brilliant maths story books, picture-book presentations of mathematical concepts that primary-school children will love.
What is volume?
Volume and capacity are important concepts in primary maths, and your child will start learning about the amount of 3D space occupied by an object in Key Stage 1. Find out how you can support their learning at home, plus the relevant mathematical formulae, with our parents' guide to volume.
What is a formula?
Formulae help children to work out answers to mathematical problems. We explain which formulae your child will be taught in primary school, including how to calculate perimeter, area and volume, and how you can help your child feel confident using a formula in primary maths.
Primary numeracy glossary for parents
From area to word problems, TheSchoolRun's primary-school numeracy glossary offers a complete guide to all the maths concepts children are taught in EYFS, KS1 and KS2. Brush up on your own mathematical skills, clear up homework confusion and understand exactly what your child is learning at school by reading our basic definitions (with links to more detailed explanations, teachers' tips and examples).
What is capacity?
We explain what capacity means and how children are taught to understand the concept in KS1 and learn about the relationship between millilitres and litres, and in KS2 use decimal notation to record the capacity of water and convert between units of measurement.
What are standard and non-standard units?
We explain what standard and non-standard units are and how non-standard units can help children understand the concept of weight before they master the skill of accurate measurement and converting units of measurement
What are two-step and multi-step problems?
We explain what two-step and multi-step problems are and give examples of typical problems a child might be asked to solve in primary school (and how the answer can be worked out!).
What is mass?
We explain what mass means, how mass is usually measured and how children are taught to convert from one unit of mass to another.
How do you 'convert into the same units'?
We explain what the phrase 'convert into the same units' means, how children are taught to convert units of measurement and techniques that teachers use to help children master this skill.
Teachers' tricks for weights and measures
Weights and measures can be a really fun area of maths to teach in school – but one that can leave parents unsure of how to help at home. Teacher Phoebe Doyle has some hints and suggestions.
