Space Dock
A twist on the broken calculator
Age: 5-11 years
Instructions:
- Help the spaceships to dock safely.
- Look at the target number. Make it two different ways.
- Some calculator keys are broken.
- There are 5 target numbers, each needed two methods.
- Based on UK Maths Programme of Study Years 1 to 6.
- Use the challenge level to adjust the difficulty.
NB: Teachers can click on the progress circles to see the methods used to make the numbers.
Have fun!
Thank you so much to Mr Flaming from Dartmouth South Academy, Nova Scotia for asking for this resource!
Breakdown of maths covered:
| Year Group |
What your child will practise |
Example |
| Year 1 | Number bonds — different ways to make the same number | Make 15: 9+6, 7+8, 12+3 |
| Year 2 | Adding and subtracting 2-digit numbers, using nearby round numbers | Make 47: 50−3, 26+21 |
| Year 3 | 3, 4 and 8 times tables; adding and subtracting tens and hundreds | Make 24: 8×3, 30−6 |
| Year 4 | All times tables up to 12×12; spotting factor pairs (can be focused on a single times table) | Make 72: 8×9, 80−8, 144÷2 |
| Year 5 | Multiplying and dividing by 10, 100 and 1,000; working with bigger numbers | Make 3,400: 17×200, 6,800÷2 |
| Year 6 | Multi-step calculations, spotting efficient routes, working with negative numbers | Make 240: 480÷2, 120+120, 250−10 |
Every puzzle can be set to 1, 2 or 3 asteroids — this only changes how big the numbers get, not what's being practised. Children must find two different ways to reach each target before the round is complete.
