But by starting the unit with some low floor activities, the students can build their confidence and it is something I can continue to refer back on. Now I know that when we get into solving and writing inequalities, that students may struggle. Again, all students were able to participate because theses were situations they experienced in their daily lives. Alternatively, we may use the Functions key in the Desmos keyboard to obtain the required functions. I had several students come up to the board and use a marker to mark their possible answers. This is happening with all the other inequalities on screen 2. For example the inequality x + 2y < 100, a dotted line should go through the point (0, 50), instead it is going through (0, 49.5).

Hi I am trying to figure why the inequalities that appear in the table on screen 3 are graphing incorrectly. Okay, that last sentence is actually not true.
it stays red all the time, while the blue, first is gray before I choose the type of line I want, then, it turn solid blue or dashed blue. The graph of the inequality is shaded in blue. Theres just one problem: Desmos doesnt do linear inequalities in one variable. Everything is working, only issue is that my Red Line, the solid or dashed button is not working like the Blue Line.

Next, I had students look at some real-world statements on the board and place possible solutions on the number line. Hi everyone: I have created this activity to graph System of Linear Inequalities. Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more. One class would only every pick whole numbers and I had to push them to see 1.5 as a value they could select.Įventually this assignment shows students how we use a shaded number line to show all possible solutions. The assignment I have linked has students place value on the number line with prompts like "a number less than 3." This starts students thinking about how there are multiple numbers that fit that prompt. There are lessons on there that you can walk students through, see what they are doing in real-time, and give immediate feedback. Have you used Desmos? You might know it as an online graphing calculator, but it is so much more. The Desmos Graphing Calculator considers any equation or inequality written in terms of r r and to be in polar form and will plot it as a polar curve or region.
