      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
