Linear Relationships

These are a couple pages I do on defining linear relationships.  This is an example of an ISN page that I do after the kids have already developed the idea themselves.  We spend a couple days looking at and graphing different patterns and they have a good idea of which ones will come out to be straight lines.  


I start this activity by giving them the definition and then getting some of their ideas and interpretations for the facts section (I might put the adding or subtracting the same number idea in the facts section instead next time).  I always make my page ahead of time, so the actual kids' notebooks had more facts filled in that they came up with during class.

Next I give them a little slip of paper with the four charts on them.  They cut them out and decide which are examples and which are non-examples.  Once they have been checked, they tape them down.  At this point, it gives me a really good idea of which kids get it and which are still a little unsure.

On the left side (we did this on a different day as part of a station activity) I have the kids create their own patterns; one that is linear and one that is not.


This activity gives me an even better idea of which kids get it, and how well they get it.  For the kids that are still a little unsure, they will usually just modify some of the examples from the Frayer chart on the right page.  I can tell which kids understand it really well because they will usually come up with more creative patterns.

Linear functions is a really big idea in pre-algebra and algebra so this is an activity that I plan to use with my algebra kids next year.  I love using Frayer charts for definitions because they give a much more complete picture of an idea instead of just a definition.

  1. I love the use of the Frayer in this context. I always find Frayers frustrating because I don't know what to put in the "non-examples" category, but a non-linear equation works perfectly in this situation.

    Love your blog!

    1. I love them so much for defining a word or concept because I think they just give such a complete picture of the idea. I have also done them with types of numbers (integers, rational, irrational) and want to do more of them this year so I'm sure that I'll be posting.

  2. Hi, I love your notebooks! I currently do one for science but am looking into doing one for Algebra 1 for math. I have a quick question for you. In order to download the printable pages, do I need to subscribe and pay the $48 a year? I am more than happy to do that, I just wanted to make sure that is what I am getting if I pay it. A link on here sent me to that site and I just wanted to make sure it is what I want:) I love your material!!!!

  3. Do you have a link to pdf copies of your interactive notebooks?
