Double the Rocket Fuel is a free printable maths worksheet for Year 2 (ages 6 to 7). Children double and halve small whole numbers to finish a space mission. They match, solve sums and circle quiz answers, all with just a pencil. Page 2 gives the grown up notes, help, a stretch idea and the answers.
It comes from the Mini Minds Hub, the free library of printables from Jaques of London, the British games and toy company that has been making games for families since 1795. Print both pages, give page 1 to your child and keep page 2 for yourself. Black and white printing works well.
What is on the sheet
Children help a rocket crew finish a mission by doubling and halving numbers. They match first, then solve sums, then circle answers in a quiz where each question has three choices. There is also a short story question about rockets and windows, so children picture what they are working out. Numbered questions have space to write the answer, so children can show their thinking.
- Double 9 =
- Half of 16 =
- Each rocket has 5 windows. There are 2 rockets. How many windows?
- Which number is double 6?
- Which number is half of 14?
A worked example: doubling
Double 4
This question uses different numbers from the sheet. It shows two ways to work. Halving is the reverse: if you halve the answer, you get back to the number you started with.
Method 1: make two equal groups- Put 4 counters in a row.
- Put another row of 4 counters underneath.
- Count all the counters together.
- Double means the same number twice.
- Write 4 + 4.
- Start at 4 and count on 4 more: 5, 6, 7, 8.
Ways to build doubling and halving
Use two equal groups
Lay out a row of counters, then add a matching row underneath. Counting both rows shows a double. Sharing the counters back into two equal rows shows a half.
Hunt for pairs
Look for things that come in twos, such as shoes, gloves, wheels on a bike or eyes on a face. Pairs show children that doubling is part of everyday life.
Say the full sentence
Encourage children to say the whole number sentence aloud, such as "double 4 is 8". Saying it helps the fact stick in memory.
Link double and half
When a child knows a double, ask for the half of the answer. Seeing that the two facts go together makes both easier to remember.
Why doubling and halving matter
Doubling means making a number twice as big. You can think of it as adding a number to itself, or as two equal groups put together. Halving goes the other way. It means sharing an amount into two equal parts and finding the size of one part. Doubling and halving are linked, so each one helps children check the other.
In Year 2, children meet doubling and halving as part of number work on multiplication and division in the National Curriculum for England. Knowing doubles by heart makes mental sums quicker, and it supports the 2 times table and later times tables. Halving also links to fractions, because a half is one of two equal parts. A space setting gives these facts a story to hold on to.

Helping your child with doubles and halves
- Double means twiceDoubling is the same number twice. It can be written as adding a number to itself. The answer is always bigger than the number you started with.
- Half means two equal partsHalving is sharing an amount into two groups that match. Half is the size of one group. The answer is smaller than the number you started with.
- Even numbers share fairlyEven whole numbers can be shared into two equal groups with none left over. Odd numbers always leave one spare. Counters make this easy to see.
- Double and half are partnersHalving undoes doubling, and doubling undoes halving. If a child gets stuck on one, try the other as a way to check.
Key words
- DoubleTwice as much. You add a number to itself.
- HalfOne of two equal parts of something.
- Even numberA whole number you can share into two equal groups with none left over.
- Odd numberA whole number that leaves one spare when you share it into two groups.
- Equal groupsGroups that all have the same number of things in them.
- Number factA short sum you know by heart, so you do not need to work it out each time.
How to use it
- Print both pages. Page 1 is for your child. Keep page 2, which has the notes and answers.
- Read the mission aloud. Children match first, then solve the sums, then circle the quiz answers.
- Work through the first few together. Talk about each choice and ask why they picked it.
- Let your child use counters, cubes or a quick drawing if they want to. There is no one right way to work.
- Check against page 2, then come back another day. Repeating a familiar activity builds confidence.
Help, stretch and game ideas
If it feels too hard
Give counters or cubes so children can make two equal groups and count them. For halving, deal the counters one at a time into two piles, like dealing cards. Then count one pile. For the story question, draw the rockets first.
To stretch confident children
Ask children to write their own double and half questions for a partner. Then they swap and solve each other's. Ask them to explain how they know, and to check each answer by doing the opposite, halving a double or doubling a half.
Make it a game
Call out a number. Children shout its double, then its half if it is even. If it is odd, they shout "odd!" instead. Take turns to be the caller, and keep to small numbers at first.
Mistakes to watch for
Watch forA child adds 2 instead of doubling, so the answer is too small.
Try thisBuild the number with counters, then build it again underneath. Count both rows to see that doubling means the whole number twice.
Watch forA child mixes up double and half.
Try thisAsk, "Should the answer be bigger or smaller?" Double makes more. Half makes fewer. Use that to check each answer.
Watch forA child shares counters into two groups that are not the same size.
Try thisDeal the counters one at a time into two piles, like dealing cards. Then compare the piles. Half is the size of one pile when they match.
Talk about it
- How would you explain what double means to a friend?
- What is the difference between double and half?
- How can you check a halving answer using doubling?
- Can you find something at home that comes in twos?
- Why can some numbers be shared into two equal groups and others cannot?
- Which question did you find easiest, and why?
Take it off the page
Pairs hunt
Walk round the house or garden and find things that come in twos, such as shoes, gloves or socks. Count how many there are in one pair, then in two pairs.
Domino doubles
Find the dominoes with the same number of spots on both ends. Say each double aloud, then halve the total spots to get back to one end.
Fair shares
Use toy cars, buttons or pasta shapes. Share them between two toy characters so each gets the same. Count one share to find half.
Who it is for
Parents
Sit beside your child for the first few questions, then let them lead. Keep it relaxed and use counters or small toys if they need them. Praise their thinking, not only the right answers.
Teachers
Use it as a starter, plenary, early finisher task, homework or table activity. It needs no preparation beyond printing. Page 2 gives support and stretch ideas for mixed ability groups, and the answers make marking quick.
Home educators
Pair it with everyday talk about pairs, sharing snacks fairly and spotting doubles around the house. It can be printed again for brothers and sisters, or used a few weeks later as revision.
Where doubling and halving fit
Before this sheet, children in Year 1 count in twos, fives and tens, and learn that a half is one of two equal parts. They also share objects into equal groups. These early experiences give doubling and halving a firm base.
After this sheet, children move on to the 2, 5 and 10 times tables and to division facts. In Year 3, doubling helps with other times tables, because some tables are doubles of others. Halving also leads on to work with fractions.
Questions parents and teachers ask
- What age is Double the Rocket Fuel for?
It is written for Year 2 (ages 6 to 7), in Key Stage 1. Younger children can try it with counters and a grown up. Older children can use it as quick revision or as a warm up.
- What will children practise?
Children practise doubling and halving small whole numbers in a space mission setting. They also use number facts and read short questions carefully, including one story question about rockets.
- Are the answers included?
Yes. Page 2 is for the grown up and has the answers, along with notes on how to use the sheet, help for children who find it hard and a stretch idea.
- Do I need to print in colour?
No. The sheet prints well in black and white on plain A4 paper. Children can add their own colour to the rockets if they like.
- What if it feels too hard?
Give counters or cubes so children can make two equal groups and count them. Work through the first few questions together, and come back to the rest another day.
- Can teachers use it in class?
Yes. It works as a starter, plenary, early finisher task, homework or table activity. It needs no preparation beyond printing, and page 2 gives support and stretch ideas.
- Is this a screen free activity?
Yes. It needs only paper and a pencil, so it suits quiet time after school, rainy days and school holidays. Children read, think and write by hand.
