### Speed Dating Activity for Absolute Value, Opposite, Reciprocal, and Opposite Reciprocal

Speed Dating is one of my favorite ways to get students out of their seat to practice. I only use this practice structure with topics that allow students to quickly do a problem in their head. If a problem type requires students to show work to figure out the answer, I will choose a different structure such as a question stack.

In case you're not familiar with the premise of speed dating in the classroom, here's a brief overview:

1. Create a deck of cards that has a question on one side and the answer on the other side.
2. Pass out the cards to students with the question side facing up.
3. Instruct each student to solve the problem in front of them before checking their answer by flipping the card over.
4. Have students stand up and find a partner.
5. Students take turns quizzing their partner and coaching/praising them.
6. Once the pair has successfully answered both questions, the partners should trade cards.
7. Find a new partner.
8. Repeat.

So, why is it called speed dating?

In speed dating, the goal is to meet as many people as possible in as little time as possible. At the end of each "mini date," you trade information in case you later decide you want to get in contact. My high school students normally love the analogy. If you don't think your students can handle the dating analogy, you can call this activity it's other common name: Quiz, Quiz, Trade.

Our first speed dating activity of this year was created to review the following vocab words: absolute value, opposite, reciprocal, and opposite reciprocal.  In the past, I've done speed dating with recognizing inequalities, naming polynomials, significant figures, and logarithms

This summer, I had an epiphany. Normally, I either hand write my speed dating cards (works in a pinch, but makes it hard to share) or type them up in publisher and print/laminate them (lots of work, but easy to share/reuse). Last year, I had a chance to buy a BUNCH of printable business cards (affiliate link) from NAEIR.

These have been a game changer for making reusable activities for my classroom. After I run them through my printer, I just snap them apart and put them in a small ziplock baggie for each group. No laminating and no cutting needed!

Here are a few example cards:

Here's some action shots of my students during our speed dating adventure. It was so hard to block out their precious faces because they were full of smiles and laughter. You could truly tell that my students were enjoying themselves while practicing algebra!

My business card sheets (affiliate link) have 10 cards each, so I made two sheets for a total of 20 cards. My largest class this year has 16 students, so this was plenty.

I intentionally printed the questions in a bold font and the answers in a small font so that students couldn't easily see the answers through the cards. Believe me, my students tried!

If you don't have access to Avery Clean Edge Business Cards (affiliate link), you can still print them on cardstock and cut them apart. You'll just need to trim around the edges with the paper chopper so all of the cards come out the same size.
