Working on Graph calc

Initially, I don’t have any idea about software graph calc since I am exploring and hearing for the first time. After tutor demonstration and explanation I came to know that graph calc is software that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. 

I know many of us wasted a lot of time plotting the graph but if we use the software graph calc within wasting much time we can able to plot the graph. For instance, if we are going to plot the graph for linear equation y=-4x+2, 2y=2x-6. To plot these two linear equations in the graph we will take a lot of time to find unknown variables for y and x-axis but if we use the software called graph calc we can easily plot the graph by typing the equations in a given box.

How do I integrate graph calc in teaching?

Firstly, the teacher needs to teach the concept of the linear equation before letting them use graph calc. For example, Linear equations are a combination of constants and variables. The standard form of a linear equation in one variable is represented as y=mx + c where c is constant/intersecting at y-axis and m is coefficient. Ex; y=2x+4. We have to teach the concept to plot the graph without using graph calc.

After knowing the basic concept to plot the graph we have to teach how to plot graph using graph calc software. For instance, we have to ask students to plot a linear equation using graph calc that is 

Y=2x+1

Y=2x+2

Y=2x+3

After students plotting graphs ask them relation or pattern that they notice from the three equations. 

Finally, to check whether students understood the concept of the linear equation gives questions to plot the graph in the chart paper without using the graph calc software. For example, ask students to plot;

Y=-4x+2

2y=2x-6

 

Check whether students can plot the graph or not in the chart paper. If the students can plot they are fully understood the concept to plot the linear equation. To check whether their graph is correct or not let same equation to plot in graph calc as shown below;
