5th Grade Math Resources for CCSS 5.NBT.1

5.NBT.1: Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.

UNPACKED EXPLANATION: We're basically talking about place value, with an explicit focus on what it means to move up a place and down a place. Within this domain, students will be expected to work with numbers from billions to thousandths. A big pitfall here is to start adding and subtracting these numbers together. The reality here is an understanding of the place value system, and what it means concretely to move between the place values.

WHAT THE PARCC WILL EXPECT: The PARCC samples are taken directly from the PARCC Practice Tests website.

The sample for 5.NBT.1 is as follows:

When you click on the drop down "Choose..." box, you're given something similar to the following:


So with all this in mind, let's take a look at some resources that are handy. I will list the location of each resource, and how it is best utilized:

I start with the class making a place value chart on the first day of school just as reference. There are multiple ways to approach this, but an easy way to do it is:

  • Anchor chart with standard, expanded, and word forms 
Another great idea I came across a few years ago is place value cups. This is a good activity for your kids who need a manipulative and need something to refer to during the entire place value domain:
  • Place value cups (click the link for instructions): This simple activity is very concrete for kids, and if you keep a few handy, they're good for reference later in the year for students who didn't retain everything they learned during the teaching of 5.NBT.1.


I'll list a few sites that have good 5.NBT.1 vocabulary. I can't really even begin to say how important it is to teach students not only what academic vocabulary words mean, but how to use them in context. There's a lot of power in having students state their reasoning academically that goes beyond testing and helps reinforce the ideas they're learning about.


I'll end each resource post with a video that most accurately explains it for kids. A lot of times, these videos may end up being from Khan Academy. He explains things well, kids enjoy learning from him, and the practice problems his website offers are spot on.
