Prop up a classroom book so that the spine is in the air, forming a miniature tent for your Elf, and sit them up inside. If you've got a little extra time, set up a few more books to form an entire campground, and create some circle "campfires" with stones or classroom supplies.

Tie a piece of string or yarn around your Elf's feet, and suspend them from a backpack hook or cubby. Explain to your students that clearly, your Elf is an adrenaline junkie.

Give your students a bit of a challenge (with a sweet reward). Post your Elf somewhere in the classroom with a note that says they've hidden X amount of mini candy canes. Set a timer, and have your students go on a candy cane hunt.

Grab a bag of mini marshmallows and spread them out on your desk or other available surface. Lay your elf on the marshmallows and form a snow angel pattern within them.

Your Elf got into trouble with some school supplies while the classroom was empty, and somehow ended up tangled in tape. Get them nice and wrapped in the tape, and leave the tape dispenser nearby so they can get caught redhanded by your students.

Tape your Elf to the classroom clock, with their arms pointing to numbers like the hands of a clock. Once your kids discover their new hiding place, give a piece of candy to the first kid who can decipher the time it's displaying.

The classroom tissue box is the perfect size bed for an Elf. Tuck them under a few tissues, and don't forget to prop up their head with a tissue pillow. Clearly, their trek to and from the North Pole wore them out.

Your thrill-seeking Elf is at it again, this time rappelling down your dry erase or chalkboard. Attach string or yarn to their hands and suspend them from the ceiling or top of the board. Then, tape their feet to the board as if they're propelling themselves with their feet.

Turns out, your Elf is also a bookworm. Prop them up in the reading corner with a good book, and encourage kids to follow their example and read quietly.

If you've got an American flag in your classroom, suspend your Elf from the flag's pole. Another option is to prop them up in front of the flag, with their hand over their heart (with the help of some tape).

Use paperclips, pencils, erasers, beads, or whatever other supply you have available to spell out a message to your students. Something like "Be good," "Listen up," or "Work hard" should do the trick.

Your students will crack up at the thought of your Elf squeezing himself into the photocopy machine after hours. Print out a few images, and scatter them around your Elf on the floor. It's their version of a selfie!

Even Elves make wish lists. Prop them up on the dry erase board, and write out a few hypothetical gifts they might ask for. Make sure to leave the marker in their lap.

If you've got any clear supply bins in your classroom, tuck your Elf inside one next to a Post-It reading "Help me!" Luckily, your Elf will magically escape the bin the next night.

Your Elf has to keep Santa updated. Let students discover the Elf typing up an e-mail or writing up a letter to Santa with the naughty and nice list on it. Get a laugh by listing all the students under "nice" and yourself under "naughty."

Grab a spare roll of toilet paper, and TP a section of the classroom. Leave the Elf propped up against the rest of the roll so students can catch them in the act.

Pick a random student (ideally, a quieter student) and tuck the Elf into their desk or pencil box. While everyone else is scouring the classroom for the Elf, they'll be delighted to find them hiding out in their own belongings.

If your class has a listening area with headphones, let your Elf take advantage of it. Place them in a lounging position with the headphones against their head.

This idea is perfect for anyone with framed pictures in their classroom. Grab a dry erase marker, and "graffiti" the pictures over the glass – think devil horns, mustaches, and funny hats.

If your class has a favorite game, obviously your Elf wants a turn. Set up a scene of them playing the game by themselves (or against a stuffed animal or other object, if you've got something that works).

For classrooms fortunate enough to have a fish tank, pose your Elf with a toy fishing pole (or a pencil with string to it). Just make sure the kids know only Elves are allowed to try this one.

Super simple, not to mention fairly plausible (after all, a puzzle is a good solitary activity for an Elf to amuse himself with when he's all alone in the classroom at night).

Pose your Elf and a stuffed animal or doll at the dry erase board and draw a few games of Tic-Tac-Toe (the Elf will most likely be the winner, right?).

Ideal for a morning when you're pressed for time, this idea uses whatever holiday decoration you've already got going in the classroom as a starting point. Hang your Elf from paper chains or put him on top of the classroom Christmas tree... the possibilities are endless.

If you're planning on sending your kids off for holiday break with a little treat (whether edible or not), pose your Elf as if he's in the process of leaving the gifts on each student's desk. The presents will be that much more exciting.
