Having Fun with Distance and Midpoint

How do you take a topic that isn’t overly exciting and get the kids to have fun with it?  I have found that getting students out of their seats and working with friends usually does the trick! 🙂

If you follow my blog you know that I have been sharing activity ideas (and free downloads) for a set of (free) ordered pair task cards that I posted last week.  Click here for my post on a slope activity and click here for my post on a coordinate plane activity.

Today I am sharing an activity on the distance and midpoint formulas:

• Have them grab a partner, find the distance and midpoint between their point and their partner’s point and then “check” their work by graphing the ordered pairs and seeing if their answers make sense.
• Have them repeat with 2 other partners.
• Challenge early finishers (or everyone) to then grab another partner. Let their point be an endpoint and their partner’s point be the midpoint.  They need to find the other endpoint.

It’s a quick easy-to-implement activity that gets kids moving and working together.  Enjoy!

Moving Around the Room with the Coordinate Plane – Activity Idea

Here is activity #2 for the ordered pair cards I posted in my last blog post.  (If you missed my post on a fun, free activity for teaching slope, you can read it here).

This is an activity on graphing in the coordinate plane that gets kids up and moving around the room:

• Give each student an ordered pair card when they walk in the room (free download link is below)
• Have them walk around the room and find someone who has an ordered pair that meets the given description. Once they find someone with an ordered pair that “works”, they need to write down that person’s ordered pair and have them sign their paper.  (The signatures ensure that the students are actually walking around the room to find ordered pairs and not just copying from a friend).  They are only allowed to have a student sign their paper once, so they will need to find 9 different people to sign their paper in order to answer all of the questions.
• After they have gathered all of their ordered pairs and signatures, they need to plot all of the points they found on the coordinate plane on the bottom of the page, labeling each of them with the given letter and their own ordered pair with a star.

I think that this lesson will be a nice way to break the monotony of simply having students graph points on a coordinate plane and write coordinates for given points.  It also makes students think more about their points than they would if they were just graphing them.  They need to think about their x-coordinate, y-coordinate, and what quadrant/axis it is located in for this activity.
