In KS3 Maths, tackling algebra means figuring out the value hidden behind a letter. It might seem tricky, but there's a cool method to help: trial and improvement.
Trial and Improvement is like clever guessing. When there's no obvious way to find a letter's value, you use the knowledge you already have to make a smart guess. You'd be surprised at how much the things you've already learned (times tables, factors, multiples etc.) come in useful!
A Parent's Secret Weapon for Smart KidsHere's an example: if x2 = 64, then 5 is too low while 10 is too high, let's guess x = 7. Test it out: 72 = 49, a bit low. How about 8? Success! 82 = 64.
Not all variables are as easy, but that's the idea. Try this quiz to get the hang of it. Take your time, read each question carefully, and give it your best shot. Good luck with your KS3 Maths journey!
