The winter break is coming to a close and it is time to think about lesson planning and review activities (review graphing
Review Graphing Often
Since the new semester continues the unit with graphing systems of inequalities, some review is necessary. Specifically, I need to review graphing, equations in both slope-intercept form, standard form and expand my former definition of a system.
Repeated Graphing Practice is Necessary
Students have had years of graphing practice, but it is never enough. It is one of those critical skills they will use again and again. When I taught 7th grade, we did a variety of activities that were fun but also required graphing practice. Part of the confusion is that students do not recognize an ordered pair as a location on the plane, and when they are plotting they want to separately plot the x value on the x-axis and the y value on the y-axis.
More Analysis and Less Drawing
I have always believed that students get distracted by all the prep work that comes with graphing: drawing the coordinate plane, labeling the parts, numbering the axis. To eliminate the distraction, I give them pre-drawn and numbered coordinate planes. I am also using a lot more online activities to practice graphing, identifying points and drawing lines. Depending on your need, there are a wide range on free online activities to practice.
Basic Online Programs
At the simplest level, give students a worksheet with something to graph and have them use either Desmos or Geogebra to graph. Both require a little practice, but both are a good basic start for students.
If you just want to avoid graph paper and have a worksheet of lines for students to graph, either GeoGebra or Demos will fit nicely. Both programs are free and when loaded will start with the coordinate plane and a place to enter an equation. Either would be an excellent choice to have students get familiar with identifying slope from a graph, look at intercepts, or even look at solutions to systems. It lessens the stress of students graphing and a teacher can address
Practice with Slope/Lines
If you are looking for a way for students to look at slope specifically or graphing lines there are several programs which give students an understanding of slope and the relationship between slope and intercepts.
Use Online Tools for Feedback
If you only have a few chrome books, set them up as a center and have students check their graphing with online tools. It is much more effective to have students compare their work to another and fix any problems than to just hear “it isn’t right”.
Either of these programs above
If you are looking for more structured practice, try the “Land the Plane” activity from teacher.desmos. Yes, it is the same great Desmos site and still free, but in this section, there are activities created for different math concepts. One of my favorite is Land the Plane. Students have to write equations to land the plane safely. It is very visual for students and a concept they are familiar with. There are many great

Until next week, practice some graphing and try something new for 2019. If you have any comments or if I can be of service to you please contact me at firstname.lastname@example.org. Or follow drop a question at my TPT store:
