Topic: Solving Square Root Equations
Date Due: Friday, August 28, 2015
Standards: CCSS.Math.Content.8.EE.A.2
Use square root and cube root symbols to represent solutions to equations of the form x2 = p and x3 = p, where p is a
positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know
that √2 is irrational.
CCSS.Math.Content.8.NS.A.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.
CCSS.Math.Content.8.NS.A.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 √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.
Family Engagement
Explain to a family member why the solution of
X2 = 25
is x = -5 and 5.
