Number line: hop on (0 to 20) · Practice set 3

What your child practises

Skills: Adding on a number line.

Understanding how numbers are built and how they relate to each other – the base for confident mental maths.

What’s included

• 4 problems
• An answer key you can print with the sheet or on its own
• An on-screen version with instant marking and stars

Age and school year

Made for ages 5–9. That’s Kindergarten – Grade 4 in the US, Year 1–5 in England, Nursery 2 – Primary 4 in Nigeria and UKG – Class 4 in India.

How to use it

• Print it at home or school – it fits a standard A4 or US Letter page.
• Print the answer key too, so marking takes seconds.
• Play it on screen: answers are marked instantly and children earn stars.
• Write on it on a tablet or touchscreen with a finger or stylus – no printer needed.

Tips for parents and teachers

1. 1Count real things first – spoons, socks, toy cars – then move to the pictures, so numbers stay meaningful.
2. 2Ask “How do you know?” about one answer. Explaining a method builds understanding faster than speed.
3. 3Let your child mark their own work with the answer key, then talk through any mistakes together.
