Q1, W3: August 27-September 1

TeacherKristin Andreason
Subject Area8th Grade Intensive Math
Grade Level8
Week #Three
Unit of InstructionUnit 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


  • 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.


  • Continue working on the Scavenger Hunt on Approximating Square Roots


  • Review approximating square roots and do more practice on white boards
  • Finish Scavenger Hunt
Assignments Due
  • Mathspace on Approximating Square Roots due August 29
  • Scavenger Hunt on Approximating Square Roots due September 1
