In this lesson you will learn calculate the rate of change of a linear function by examining the four representations of a function.Love this!
Just found it on pinterest. It's perfect for my algebra class. Very good activity and it's exactly what I've been looking for! Where can I find the files you used for this activity? I don't want to "reinvent the wheel" if you are willing to share your files.
Thanks in advance! I am so glad that ya'll like the activity.
Slope Rate Of Change
Unfortunately I don't have an electronic copy. I hand wrote all of the cards, drew all the pics etc. I will eventually create an electronic version, but have no idea when.Algebra Basics: Graphing On The Coordinate Plane - Math Antics
So sorry :. Great activity! You should look into TpT when you get the electronic version. TpT is a site where teachers pay teachers for their products. Check it out! Then I'll buy this from you!
This is wonderful! I teach in a community college and I am trying to create a "flipped classroom" for Intro Algebra - this is a great in-class activity after they study the material independently. Thanks for sharing! I know exactly what you mean, this is such an exciting area as its like 3 pillars of maths coming together equations, graphs and tables so why cut it short!

Seventh Grade. Students also were exposed to examples of rates as the comparison by division of two quantities having different attributes, including rates as quotients. In seventh grade, students must use their knowledge to represent constant rates of change, which is the predictable rate at which a given variable alters over a certain period of time by representing and identifying this change when given pictorial, vertical or horizontal tables, verbal, numeric, graphical, and algebraic expressions.

Readiness Standard 7. Click here to submit feedback. Google Drive. Questions or Feedback?Why have I never thought to have the kids put the units when finding the slope from a table. You're a genius!!! I was thinking the same thing! Too bad I just finished my linear functions unit. I'm putting that on the list for next year though or when we review before EOC. The link takes us to your old rate of change foldable--not the one pictured. This year, I'm structuring things a bit differently in Algebra 1.
Some changes have been for the better, and some haven't. I've already started making a list of things to keep and change for next year. Today, I want to blog about one of those things worth keeping. It's the type of thing that makes me wonder, "Why have I never done this before?!? Yesterday, I posted about a Ghosts in the Graveyard game I made to review independent and dependent variables.
They were in the standards, so I taught them. But, I never took the time to connect independent and dependent variables to the other concepts we were learning. No wonder I felt like it was a pointless thing to teach! This year, I decided to teach finding rate of change directly after teaching independent and dependent variables. It was a beautiful thing to watch it unfold! Every time I gave my students a table or set of points, we classified the variables as dependent or independent before moving on to finding rate of change.
I defined rate of change for my students as the change in the dependent variable divided by the change of the independent variable. My students are finding the slope, but they don't know that yet. Most of my 9th graders come in my room with a history of either loving slope or hating slope from their middle school years.
By focusing only on rate of change and not slope, I'm giving them each a fresh start. Here are the notes we ended up taking on calculating rate of change from a table or set of points.

HandoutsInteractive Notebooks. Add to cart. Wish List.A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable, then. Rates of change can be positive or negative.
This corresponds to an increase or decrease in the y -value between the two data points. When a quantity does not change over time, it is called zero rate of change. When the value of x increases, the value of y increases and the graph slants upward. When the value of x increases, the value of y decreases and the graph slants downward. When the value of x increases, the value of y remains constant.
That is, there is no change in y value and the graph is a horizontal line. The rate of change is 40 1 or This means a vehicle is traveling at a rate of 40 miles per hour.

Rate of Change A rate of change is a rate that describes how one quantity changes in relation to another quantity. Positive rate of change When the value of x increases, the value of y increases and the graph slants upward. Negative rate of change When the value of x increases, the value of y decreases and the graph slants downward.
Zero rate of change When the value of x increases, the value of y remains constant. Example: Use the table to find the rate of change. Then graph it. Subjects Near Me.

Keep kids learning with daily schedules and activities. Go to Wide Open School. Create Lesson Plan. This lesson flow will introduce pre-algebra students to the concept of rate of change and how it translates to a visual graph. Students will go beyond plotting points on a graph and connecting them to make a line - they will understand the meaning behind the change in the relationship represented by the function.
Students might give their opinions on whether they believe we can or cannot truly predict the future, give examples of how we try to predict the future in daily life, or posit what kind of information we might need to predict future events. At the end of the lesson, students can revisit their thoughts and how they relate to what they have learned. The "Domino Effect" lesson on Mathalicious is available for free and is a fantastic introduction to the concepts of slope and y-intercept based in a topic every middle school student loves - pizza!
They then answer questions about the essential features of the graph: what does the y-intercept represent? Start with the video "Slope and Rate of Change" to give students guided examples of finding the slope of a line from a graph or set of ordered pairs.
Students can then explore related problem solving videos in small groups or under guidance from the teacher. As an alternative or extension activity, have your students hit YouTube or another video sharing service, and find their own videos of guided problem solving. They can then share the videos they think are most helpful with their classmates.
IXL gives feedback when a student gets a problem correct or incorrect, provides a SmartScore to let students know how they are doing overall, and gives prizes when students master each skill. Best of all, the teacher can see all students' usage statistics, such as time spent on each problem and rate of accuracy.
Twitter is a great way for students to boil down what they have learned into characters. To put everything together from this experience, have students find Creative Commons licensed images of linear graphs. Then, they can tweet the picture with a brief qualitative statement about the essential features of the graph.
What does the y-intercept represent? What change does the slope represent? Where might the graph be going? Compare properties of two functions each represented in a different way algebraically, graphically, numerically in tables, or by verbal descriptions.
