Graphing Solutions on a Number Line Speed Dating

Recently, I wrote a blog post sharing a set of speed dating cards I created to review absolute value, opposite, reciprocal, and opposite reciprocal using printable business cards (affiliate link).

I used the blank template I created to create a new set of speed dating cards for a different topic: graphing solutions on a number line.

I've done this activity in the past, but I had always handwritten the questions/answers on index cards. This worked well enough, but it meant I couldn't share the file with others.



Here's my newly designed version using Avery printable business cards (affiliate link).






The backs of the cards have the answer printed so partners can easily check each other's work.



These cards test that students know how to graph the following types of solutions on a number line:
* is equal to
* is not equal to
* is greater than or equal to
* is greater than
* is less than or equal to
* is less than

So, how does speed dating work?

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.

Here are a couple of action shots from the day we used these in class:



I have uploaded the file for these speed dating cards here. If you don't have access to printable business cards (affiliate link), you could print them and cut off the excess margins before cutting the cards apart.
