⚖️ Equation Balance
The scales are level, so both sides weigh the same. Work out what one x-box weighs, from x + 3 = 8 up to x on both sides.

What it practises
- Maths calculation: Arithmetic, fractions, ratios, powers and number bases at a steady pace.
- Concepts & theory: The science and maths behind the game: reflection, orbits, waves, circuits, ciphers.
Games are good for calculation speed and accuracy. Mathematical concepts still need teaching and explanation.
Quick lesson: Keep the balance
An equation is a balance: both sides weigh the same. Whatever you do to one side, do to the other. Take away the loose weights first, then divide by the number of x-boxes.
Check question
Solve 3x + 4 = 19.
- x = 5
- x = 15
- x = 23/3
- x = 7
Answer: x = 5. Take 4 from both sides: 3x = 15. Divide both sides by 3: x = 5.
