### In the lessons

In maths, estimation means rounding numbers to check whether an answer is sensible, or guessing how many sweets are in a jar or how long a line is. In science, you estimate before measuring. In everyday life, «go up / down in someone's estimation» means they think better or worse of you. Phrases: «a rough estimation», «in my estimation», «go up in someone's estimation».
