Strand: NUMBER AND OPERATIONS IN BASE TEN (3.NBT)

Use place value understanding and properties of operations to perform multi-digit arithmetic. A range of algorithms may be used (Standards 3.NBT.1-3).

Standard 3.NBT.1

Use place value understanding to round whole numbers to the nearest 10 or 100.

• Grade 3 Math Module 2: Place Value and Problem Solving with Units of Measure (EngageNY)
  Module 2 uses place value to unify measurement, rounding skills, and the standard algorithms for addition and subtraction. The module begins with plenty of hands-on experience using a variety of tools to build practical measurement skills and conceptual understanding of metric and time units. Estimation naturally surfaces through application; this transitions students into rounding. In the modules final topics students round to assess whether or not their solutions to problems solved using the standard algorithms are reasonable.
• Grade 3 Unit 1: Number and Operations in Base Ten (Georgia Standards)
  In this unit, students will investigate, understand, and use place value to manipulate numbers. Build on understanding of place value to round whole numbers. Continue to develop understanding of addition and subtraction and use strategies and properties to do so proficiently and fluently. Draw picture graphs with symbols that represent more than one object. Create bar graphs with intervals greater than one and use graphs and information from data to ask questions that require students to compare quantities and use mathematical concepts and skills.

• Rounding to 50 or 500
  In this task students are asked questions about rounding to the nearest ten and the nearest hundred.
• Rounding to the Nearest 100 and 1000
  Part (a) of this task fits squarely within third grade when students "use place value understanding to round whole numbers to the nearest 10 or 100". Part (b) is a first step in rounding beyond tens and hundreds.
• Rounding to the Nearest Ten and Hundred
  The purpose of this task is for students to practice rounding numbers to the nearest ten, connect the rules for rounding with location on the number line, and to introduce the idea of rounding to the nearest 100.
