I have the kids switch every few minutes, and that way they are communicating a lot with their partner about how to improve their graphs. Learn more. Skip to content. Include media. I had never done this part of the activity before, and I was amazed at the connections my students were making. Day 6 This is the day when it all came together for my students. I find that kids understand the distinction better when we start outside of "math world" for a while. Once we finished the warm-up which was really a full lesson in disguise we started looking at other ways that functions present themselves.

Instruction complex numbers composition of functions Compound Inequalities. Thursday, my Algebra 1 students finished our unit on Absolute Value Graphs and Inequalities. My first goal was to get students to graph absolute value functions by making an. Posted by Sarah Carter (@mathequalslove) at PM. Math = Love: Absolute Value Foldables and a Punch Story.

Here is what we can put in the calculator:. Then they share with their tablemates. To review how to obtain equations from linear graphs, see Obtaining the Equations of a Line, and from quadratics, see Finding a Quadratic Equation from Points or a Graph.

Follow more accounts to get instant updates about topics you care about. I even had kids say things like "If you draw a line straight up the middle, it goes through the graph two times.

## Piecewise Functions She Loves Math

Sometimes the graphs will contain functions that are non-continuous or discontinuousmeaning that you have to pick up your pencil in the middle of the graph when you are drawing it like a jump!

I almost never have students who get all ten matches correct on their first try.

You can add location information to your Tweets, such as your city or precise location, from the web and via third-party applications. Video: Functions math equals love absolute Absolute Value function, -Equations-, -Inequalities- and -graphing with transformations-!! Before the Unit. Either by prodding or hinting, I get them to realize that all the outputs are less than the inputs. Day 5 On this day, I make a hard shift from graphs and go back to my function machines. They do. On the first day of the unit, I used Function Carnival from Desmos. But that's not what I did this year. |

What this means is for every x less than or equal to –2, we need to graph the line 2x+8, as if it were . We can write absolute value functions as piecewise functions – it's really cool! . You plan to sell She Love Math t-shirts as a fundraiser.

My first rule, "add 6" was pretty easy, but my second rule, "double and add 4" was hard for students to follow, so they asked me to write the answers on the board.

But I still haven't used the word "function. I then have kids come up with their own examples: three functions and three non-functions. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output. Last year, I did a big unit on linear functions and then went to functions more generally.

We can see that the parent absolute value function is flipped vertically, move to the left 2and up 1. Tap the icon to send it instantly.

As kids were discussing their justifications, I noticed that a lot of kids had intuitive thoughts about the way that slope represented speed in the stories. Save list. Sometimes the graphs will contain functions that are non-continuous or discontinuousmeaning that you have to pick up your pencil in the middle of the graph when you are drawing it like a jump!

Below is an outline of what I did over the past couple of weeks, along with notes on what I'd change next time.
You might want to review Solving Absolute Value Equations and Inequalities before continuing on to this topic. This might be a way to get kids thinking more about independent and dependent variables. The reason this is a good option is that we've spent two days looking at distance-time graphs, and I don't want kids to believe that distance and time are the only variables we can graph on a coordinate plane! As kids were discussing their justifications, I noticed that a lot of kids had intuitive thoughts about the way that slope represented speed in the stories. After every group of students has done at least one draft of their answers, I call on students to match and justify one story and graph. |

Before the Unit.

What is going on?

Here is the function again:. I figured this out by knowing the factors, and taking a good guess!
