Q1, W3: August 27-September 1 Teacher Kristin Andreason 8th Grade Intensive Math 8 Three 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 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.

Classroom Activities

Monday/Tuesday:

• Identify squares of numbers 1-15 and talk about squares/square roots.
• Talk about number lines containing an infinite number of numbers, including square roots.
• Demonstrate how to approximate square roots to the nearest tenth (or hundredth)
• Practice approximating square roots on white boards.
• Math Space assignment (Approximating Square Roots) and Scavenger Hunt on Approximating Square Roots.

Wednesday:

• Continue working on the Scavenger Hunt on Approximating Square Roots

Thursday/Friday:

• Review approximating square roots and do more practice on white boards
• Finish Scavenger Hunt
Assignments Due
