### Resources for Rounding (3.NBT.A.1, 4.NBT.A.3, 5.NBT.A.4)

Common Core State Standard 3.NBT.A.1 asks students in Grade 3 to "use place value understanding to round numbers to the nearest 10 or 100." Fourth graders (4.NBT.A.3) must "use place value to round multi-digit whole numbers to any place." By fifth grade, the Common Core requires students to round decimals (5.NBT.A.4). Let's take a look at some free or inexpensive resources available to teach rounding.

Rounding Activities and Worksheets, created by Kholmquist, is a great place to start with third grade students. For some seasonal fun, try Pick a Pumpkin Rounding Game or Jack-o-Lantern Rounding, created by Elena Fryer. Finally, engage your third graders with some hands-on fun using Rounding to the Nearest 10 or 100 Place Value Mystery Pictures by Loreen Leedy.

Several terrific products employ technology to teach this concept. Rounding Robots PowerPoints & Printables by Jan Lindley  and Rounding Numbers Round-Up SMARTboard and Game Bundle by Amy's SMART Designs will really engage your engage third and/or fourth grade students.

Fourth grade teachers will love Rounding the World, a product created by Dennis McDonald that includes two graphic reference sheets, 32 task cards, three activity sheets, and an answer key. MJcreations offers several games to help students practice their rounding finesse, including Rounding to the Nearest 10 and 100 - Match GameRounding Six Digit Numbers - Memory Match Game, and Place Value Match Game.
