# Measures (Year 3)

In KS2 Maths, you'll discover cool things about measures! Year Three is where the magic happens. You'll meet grams and kilograms, litres and millilitres, and centimetres, metres, and kilometres. It's like choosing the perfect superhero for different jobs – centimetres for short, metres for medium, and kilometres for super long lengths!

Millimetres, centimetres, and metres are like measurement superheroes. They help us measure length (like how tall you are), mass or weight (for heavy or light things), and liquid capacity (like your water bottle). Measurements are part of our everyday adventures – even when picking out new trousers and shoes, we need to know the size of our waist and feet!

Join the fun and take our measures quiz to see how you measure up with measures!
