Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π^2). *For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations*.
1 interactive, auto-graded activity for 8th grade students practising 8.NS.A.2. Mini Labs put the standard to work in a real scenario; Skill Practice builds fluency on the standard alone. Every one is randomized per student, so each learner gets their own numbers.
Interactive 8th grade number line worksheet for locating irrational square roots (8.NS.A.2). Students click to place values like √13 between whole numbers, then zoom in to estimate to the nearest tenth, with instant validation and feedback. Auto-graded, randomized per student, and built around a real-world surveyor scenario that makes estimation feel purposeful.
