Understand the place value system (Standards 5.NBT.1-4). Perform operations with multidigit whole numbers and with decimals to hundredths (Standards 5.NBT.5-7).

Standard 5.NBT.4

Use place value understanding to round decimals to any place.

  • Base 60: Babylonian Decimals
    An Annenberg Learning Math video introduces students to the Babylonian number system in base 60. In the classroom activity they review base 10 and apply their understanding to write numbers in base 60. NOTE: You have to create a Free PBS Account to view this web page, but it is easy to do and worth the effort.
  • Grade 5 Math Module 1: Place Value and Decimal Fractions
    In Module 1, students understanding of the patterns in the base ten system are extended from Grade 4s work with place value of multi-digit whole numbers and decimals to hundredths to the thousandths place. In Grade 5, students deepen their knowledge through a more generalized understanding of the relationships between and among adjacent places on the place value chart, e.g., 1 tenth times any digit on the place value chart moves it one place value to the right. Toward the modules end students apply these new understandings as they reason about and perform decimal operations through the hundredths place.
  • Grade 5 Unit 2: Adding and Subtracting with Decimals (Georgia Standards)
    In this unit students will solve problems by understanding that like whole numbers, the location of a digit in a decimal number determines the value of the digit. Understand that rounding decimals should be sensible for the context of the problem. Understand that decimal numbers can be represented with models. Understand that addition and subtraction with decimals are based on the fundamental concept of adding and subtracting the numbers in like position values.
  • Number and Operations in Base Ten (5.NBT) - Fifth Grade Core Guide
    The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for Fifth Grade Mathematics - Number and Operations in Base Ten (5.NBT)
  • Rounding to Tenths and Hundredths
    The purpose of this task is for students to use the position of a number on the number line to round the number without knowing its exact value. Though this task deals most directly with rounding, it also requires students to understand or figure out that one tenth of 0.1 is 0.01.
