## 5.NBT.4: Use place value understanding to round decimals to any place.

**UNPACKED EXPLANATION:**Round decimals to either tenths, hundredths, or thousandths, although strategies and skilled learns should apply to any place.

**WHAT THE PARCC WILL EXPECT:**The PARCC Practice Tests question for 5.NBT.4 tests students ability to round decimals without a given context (without telling them "round to the tenths place," etc.). The actual problem is:

The PARCC does this quite a lot. There are 6 numbers that can be dragged, meaning that two numbers will be left behind, so the traditional test taking strategies, especially process of elimination, won't be as effective here (although it still helps). Students will need the ability to do exactly what's laid out above, to be able to match numbers to their rounded counterparts, and do it without context.

**RESOURCES:**I'll focus on resources that cover all the components of this skill. You'll likely want to start with doing a lot of rounding with context, and eventually move to the more rigorous side of this standard.

**ROUNDING WITH CONTEXT:**- Short explanation before some rounding of specified digits
- 4 page packet that rounds with context
- Mathworksheetland.com lesson outline: It's all context based rounding here.
- Massive listing of worksheets from internet4classrooms.com: Tons and tons of context based rounding sheets, I mean TONS.
- Assessment for 5.NBT.1-4: Actually some decent problems here.
**GAMES****ROUNDING WITHOUT CONTEXT:**There's not a lot out there for rounding decimals that leaves no context. My advice here is to look at the PARCC problem above and craft some problems that are similar to it, this ensures students are getting rigorous problems that make them problem solve and think. I highly recommend going to that level if possible,- Performance assessment task from insidemathematics.com: Look through this document for a few rigorous problems with scoring rubrics. They could be used for practice or even incorporated into assessments.
- Iowa released test items: Released items from the old NAEP test that are now aligned to CCSS (interstingly enough, a lot of these problems were originally meant for 7th and 8th graders). Search the document (ctrl+f) for 5.NBT.4.
