MA.8.NSO.1.1 · Number Sense and Operations and Probability
Irrational numbers are the 8th grade extension of the number system to values like √30 and π that never end and never repeat. Students decide whether a number is rational or irrational, estimate an irrational value between two whole numbers, then sharpen that estimate to place an expression such as 1 + √30 on a number line.
On the FAST, this shows up as multiple choice items asking which two integers a square root falls between, multiselect items where students pick every irrational value in a list, and drop-down items completing an estimate. The scientific calculator makes the estimating easy, so the trap is classification, not arithmetic.
These come straight from Algebro's 8th grade pre-algebra question bank, easiest first. Answer one, check it, then move to the next.
