About this worksheet

Choosing and writing units in science. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

I can pick a sensible unit for a length, mass, volume, time, speed or temperature, in metric and customary units.
I can match SI symbols to their quantities: m, kg, s, L, °C, m/s, m/s², N, J, V and A.
I can write a measurement the SI way (a space, the exact symbol, no plural s, no period) and spot a value with the wrong unit.

Standard: practices (no PE code)

Words to know

quantity: What is measured: length, mass, time, volume, temperature

unit: The amount we count in, such as a meter or a second

symbol: The short way to write a unit, such as m or kg

SI: The International System of Units, the metric system scientists use

customary units: US units such as inches, pounds and gallons

Common mistakes

Your child chose the right unit but wrote its symbol the wrong way. SI symbols have one form: a space before, exact capitals, no plural s, no period. Try fixing a few labels together, like 25 kg.

Your child used a unit for a different quantity, such as liters for a mass. Each quantity has its own unit. Try naming what is measured first, then the unit.

Your child chose a unit for the right quantity but far too big or too small. Try picturing the number with the unit: 18 cm is a pencil; 18 m is a bus or more.
