In KS3 Maths, you'll tackle problems with big numbers. Before diving into calculations, it's smart to have a rough idea of the answer, and that's where approximations come in.
Approximations give you a general sense of what the result might be. While you'll still do the actual calculations, dealing with rounded numbers makes things much easier, especially when they end in zeros.
Make Learning Exciting - How quizzes helpRounding up or down to the nearest 10, 100, or 1,000 can simplify complex problems. For example, if you're asked to multiply 87 by 23, rounding makes it simpler: 90 x 20 = 1,800. It's not the exact answer (87 x 23 = 2,001), but it's close. Approximations help you check if your answers are on track.
Test your skill with approximations in the quiz below. Take your time, read each question carefully, and good luck with your KS3 Maths adventure!
