# Q1, W3: September 14-18 Pre-Algebra

Teacher Kristin Andreason 8th Grade Pre-Algebra 8 September 14-18 Unit One--Rational and Irrational Numbers
Standard(s) Taught

MAFS.8.NS.1.2:  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.

MAFS.8.EE.1.2:  Use square root and cube root symbols to represent solutions to equations of the form x squared = p and x cubed = p, where p is a positive rational number.  Evaluate square roots of small perfect squares and cube roots of small perfect cubes.  Know that the square root of 2 is irrational.

Learning Targets and Learning Criteria
• Students will review squares of numbers from 1-15 and understand that taking the square root is the opposite (inverse) of squaring a number.
• Students will be able to locate irrational numbers approximately on a number line.
• Students will learn how to approximate the square root of non-perfect square numbers to the nearest tenth.
• Students will learn how to determine the square root of a non-perfect square to the nearest integer.
