Unit 2 FAL – Rational and
Irrational Numbers
Standard
8.NS.1. Know that numbers that are not rational are called
irrational. Understand informally that every number has a decimal expansion;
for rational numbers show that the decimal expansion repeats eventually, and
convert a decimal expansion, which repeats eventually into a rational number.
8.NS.2. 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., π2
). For example, by truncating the decimal expansion of, show that is
between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to
get better approximations.
Objective
SWBAT distinguish between rational and irrational numbers and
show mastery by completing an exit slip with 80% accuracy.
