About Doubles Fill-in Worksheet

Doubles Fill-in Worksheet helps Grade 1 learners master one of the most useful early addition facts: doubles. Each question shows a number and asks the child to double it and write the answer, reinforcing the idea that doubling means adding a number to itself. Knowing doubles by heart is a genuine shortcut in mental maths — it makes near-doubles (like 6 + 7) and later multiplication far easier — which is why doubles fluency appears in Year 1 and Year 2 expectations across the UK, Australia, Canada and the US Common Core. The five levels gently grow the range of numbers so the same child keeps being challenged as their recall improves, and every problem is generated fresh so the worksheet can be reused. Each page prints cleanly on a standard A4 sheet in black and white, and every level downloads with its own complete answer key so a parent or teacher can mark the work in seconds. There is no advertising, no sign-up and no data leaves the device. Use it for daily fact practice or alongside our doubles games for the same age range.

A hand for grown-ups

Before you start
Have something countable nearby. Being able to check "3 and 2 really is 5" by counting builds trust in the maths.
While they work
If a sum is hard, suggest counting on from the bigger number rather than counting both from one. It is a real strategy, not a crutch.
Afterwards
Try one together out loud, talking through how you worked it out. Hearing an adult think aloud is genuinely useful.
Watch out for
Counting both numbers from one every time. Nudge gently towards "start at the bigger one and count on".
Away from the screen
Add up small shopping items, or dots on two dice. Board games with dice are addition practice in disguise.
