If you see a statement with an inequality symbol (>, =, <=), follow the three steps: As well as the familiar equals sign () it is also very useful to show if something is not equal to () greater than (>) or less than (<) These are the important signs to know.

This test-point does not satisfy the linear equality, so we choose to leave the side that contains (0, 0) blank and instead, shade the other side. 3 for 2 Offer on all Classroom Capers posters Buy any 3 posters and pay for only 2 - discount applied at check out. The image of the real crocodile will be really helpful for my SEN. Creative Commons 'Sharealike' Reviews smason1966 a year ago report Thank you, loved this. Also downloaded the greater than/less than crocodiles from Twinkl, laminated them and gave them to the pupils for scaffolding. Here, substitute (0, 0) into the original linear equation. PowerPoint to introduce symbols and worksheet to go along with it. Shop affordable wall art to hang in dorms, bedrooms, offices, or anywhere blank walls arent welcome. If it does not, leave the side that contains the test point blank and shade the other side. Unique Equal Is Greater Than Posters designed and sold by artists. If it satisfies the linear inequality, shade the side that contains the test point. So how do you figure out which half-plane to shade? The easiest way is to pick a test point, usually (0, 0), and substitute it into the inequality. The shaded area contains all the points that satisfy the original inequality. Lastly, when graphing the linear inequality, you need to pick one side of the boundary line to shade. If the linear inequality uses '>' or ' 4x + 2 uses a “>” symbol, so it is a strict inequality that requires a dotted line. The boundary line divides the plane to show which areas contain all the points that satisfy the inequality.

This will show whether to use a solid line or a dashed line for the boundary line.

Second, students should read the whole inequality, naming numbers and symbols left to right, like they would read any sentence. If they forget which is which, I like to point out that the less than symbol makes an L. Im going to introduce the work station that goes along with it this week. cash wage of at least 2.13 per hour do not equal the minimum hourly wage. We used this chant We also made cute little alligators with popsicle sticks and googly eyes from One Extra Degree. 12/ No more than 3 hours on a school day or 18 hours in a school week. The second step is determining if the inequality is strict. First, explicitly teach that the symbols have names. Alligator, Alligator We just finished teaching greater than, less than, and equal to this past week. Then you graph it just as you would a linear equation. You would start by rearranging it such that it reads, y > 4x + 2. Greater than (>), less than ( 4x as an example. To review, a linear inequality is any statement that includes a symbol other than the equal sign. Graphing linear inequalities is similar to graphing linear equations but with the added steps of picking a solid or dotted line and determining what part of the coordinate plane to shade in order to make the inequality a true statement.
