Measurement
This topic covers 3 learning steps, guiding your child from the basics through to confident problem-solving. Each step includes a worked example and adaptive practice questions.
What Your Child Will Learn
- cm and m
Compare lengths in cm and m - g and kg
Compare masses in g and kg - Convert Units
Simple unit conversions
Common Mistakes
- Mixing up centimetres and metres (not understanding how big each unit is)
A centimetre is about the width of a finger. A metre is about the length of a guitar. Get your child to memorise these benchmarks so they can estimate sensibly. - Measuring from 1 on the ruler instead of 0
A ruler starts at 0. If you start at 1, your measurement will be 1 cm too long. Show your child the 0 mark and practise placing objects right at the edge.
Tips for Parents
- Measure things around the house together: "How wide is the table? How long is the sofa?" Record results in cm and m.
- Estimate before measuring: "How long do you think this book is?" Then measure to check. This builds a feel for units.
- Bake together using scales — measuring 200g of flour and 50ml of milk is practical maths.
- Compare measurements: "Your foot is 18cm and mine is 26cm — how much longer is mine?" This connects measuring to subtraction.
Key Words
- Centimetre (cm) — A small unit of length — about the width of a finger.
- Metre (m) — A larger unit of length — about the length of a guitar. 100 cm = 1 m.
- Kilogram (kg) — A unit of mass — a bag of sugar is about 1 kg.
- Litre (l) — A unit of capacity — a large bottle of water is about 1 litre.
- Estimate — Make a sensible guess before measuring — then check.
Where This Fits
Before this topic: Children should compare lengths using non-standard units and know basic comparison vocabulary (longer, shorter, heavier).
After this topic: Measurement in standard units leads to calculating perimeter, area, and volume, and converting between units in later years.
How MathCraft Teaches This
In MathCraft, Measurement is taught through the Money, Data & Measure adventure track. Your child follows guided lessons with friendly characters, works through examples step by step, then practises with questions that adapt to their level.
The adaptive engine tracks mastery across all 3 steps, revisiting concepts your child finds tricky and advancing when they're ready. Parents can see detailed progress in the Parent Dashboard.
