Let’s be real, instructor friends—some days you’re just plain exhausted.
You’ve explained fluid intake calculations three different ways, and still… blank stares. Or worse—nodding heads that turn into confusion on the test.
If you’re tired of doing all the talking while your students zone out, I’ve got good news:
There’s a simple classroom strategy that brings the energy back—for everyone.
It’s called centers—and they just might be the cure for teacher exhaustion and the boost your students need to actually get excited about learning.
Why Centers? Because Teaching Shouldn’t Be Draining

Centers allow students to:
- Work in small groups (built-in peer support)
- Rotate through different learning styles and formats
- Stay focused and engaged the entire class period
- Get the repetition they need—without zoning out
And let’s be honest: Centers take your teaching fatigue down about five notches.
Here’s How to Set It All Up
Before the rotations start, spend 15–30 minutes reviewing the main content for the current unit of study:
For example:
- Common fluid containers and volumes
- Fluid conversion basics (oz to mL and vice versa)
- How to read and total an intake and output sheet
Display any helpful information on the board for students to reference during the activity (like fluid intake conversions).
Prepare (cut index cards, place puzzle pieces in baggies, place test questions and answer keys at each table) the stations.
I like to use 6 stations of 4-5 students per station.
You choose the work groups

A quick note about groupings—choose them yourself.
While it might be tempting to let students pick their own groups, I highly recommend assigning them instead.
Why?
Because we all know what can happen: one student ends up doing all the work while their friend zones out—or worse, students cover for each other when someone isn’t participating.
By creating your own groups, you can balance student abilities, personalities, and participation levels to ensure that everyone contributes and gets the most out of each activity.
Plus, it sends the message that this is a learning environment first, not social hour.
Trust me on this one.
Set the Ground Rules

These should be posted at every table and projected before the activity to be reviewed aloud:
- ✔️ Work the entire time (7–8 minutes per station)
- ✔️ Work only with your group (4–5 students per station)
- ✔️ Use Volume Level 2 voices (just above a whisper)
- ✔️ Complete your Points Sheet and attach any required work
❌ Not following the rules = zero points for that station
Project a station layout map and the rotation order on a screen.
Keep a timer visible so students can monitor their progress and know when to switch.
The timer pictured above comes up in Google search first on the list and I simply display it on the screen in front of the room during the activity.
6 DIY Centers Station Ideas
Station 1: Google Slides Points Game

Create a Google Slides presentation with one question per slide with the next slide giving the answer.
✅ Students solve each together.
✅ For every correct answer, they earn 1 point and keep track on their Points Sheet.
Tip: YOU set up one laptop/chrome book on the tabletop and place the slides in “slideshow” view before each group begins to prevent them from seeing the answers.
Station 2: Matching Game

Make your own version using index cards or cardstock.
Any test question or problem can be used.
Simply cut the index card in half with the problem or term on one half and the answer on the other.
I would recommend having at least 16 questions or problems.
For example:
✏️ One set of cards has questions like “NPO”
✏️ The other half has the definition.
Once cut in half, shuffle the “half” cards and place them on the table for students to “match”.
✅ Once students match all cards, they call you over to check.
✅ Every correct match = 1 point on the Points Sheet.
Station 3: Simulated Scenarios or Skill Practice
This is a perfect way to make sure all students practice a skill!
Have a complete simulated skill scenario for each group to rotate through where they practice the skill (or skills) that go with the unit of study.
Have the skill steps available for them to reference.
Remember this is practice!

Station 4: Color-It Review

Print a simple elementary-style coloring page (something like a flower, sun, or a frog).
Ask as many questions as you have items to color related to the unit of study.
I like to number the items to color.
✅ For each correct answer, students get to color one item on their page.
✅ Attach the coloring page to the Points Sheet as proof of participation. Plus you can see how many questions they answered correctly.
Remember: ALL age groups love to color…even my adult CNA students.
You’re obviously not concerned with their coloring ability…just questions answered correctly.
Tip: I made this picture in Canva.
Station 5: Mystery Puzzle Game
Use a 24-piece puzzle. This 6 pack of puzzles from Amazon is a great deal (No I’m not affiliated with Amazon in any way).
🧩 Ask 24 different review questions on fluid intake.
✅ For every correct answer, the group earns a puzzle piece.
Students work together to assemble the puzzle using only the pieces they earned.
Their score = number of pieces placed.
Tip: Have the pieces in a large one gallon freezer bag. Each time they answer a question correctly, they get to pull a piece out of the bag.
Station 6: Card Game
This one’s a class favorite! 💩
Write review questions on index cards and place them face down in a bedpan or other health related container.
✅ A student pulls a card and reads the question aloud.
✅ If they get it right, they keep the card.
❌ If they miss it, it goes back in.
They track how many cards they earned on their Points Sheet.
⏱️ Wrapping It Up
Once every group has rotated through every station, the activity is over and the students participated in the “We do” part of the “I do, we do, you do” part of the learning process.
The emphasis should be placed on active participation and practice.
BUT…we also need accountability.
So I make sure students are recording their progress through the stations on a “Points” sheet to turn in and attach any evidence they have to the “Points” sheet (ie. the coloring page.
Want a Pre-Made Version of Center Activities for Your Fluid Intake Calculation Lesson?
If you’d rather not DIY everything, I’ve bundled all these activities and more in a printable & digital Fluid Intake Mega Bundle on TpT.
It includes:
- Printable worksheets
- Google Slides game
- Matching cards
- Simulated scenarios
- Color by code
- Puzzle games
And yes—even a printable “Oh Crap” game!
So, What's the takeaway?
Using centers in your CNA or PCT classroom is like flipping on the lights—you’ll see your students engage, think, talk, and even laugh while practicing a critical skill.
No more glazed eyes and no more dragging through intake logs.
Just active learners… and a way less tired teacher. ✨
You’ve got this!
