Module 2
Place Value and Problem Solving
with Units of Measure

Overview

Throughout this Module, students will:
  • tell and write time to the nearest minute using analog and digital clocks
  • understand that an analog clock is a portion of the number line shaped in a circle
  • use the number line and clock to solve addition and subtraction problems within an hour
  • measure using kilograms, grams, liters, and milliliters
  • estimate volumes and masses of familiar objects
  • estimate to reason about addition, subtraction, multiplication, and division word problems
  • round two, three, and four digit measurements to nearest ten or hundred
  • round to estimate two and three digit measurements then calculate to determine exact answer using the standard algorithm
