It is so hard to correct or grade those graphs of inequalities my students would produce for me, yet I needed them to practice the skills of graphing the borderline, dotted versus shaded, and which side to shade. Most of them looked like a scribble mess even when I provided pretty colored pencils or markers for shading. Therefore I created this Matching Task Card Activity to assess the same skills but not have to look at those messy graphs.
This product contains 36 Task Cards of Inequality Graphs and 36 Task Cards of Inequalities. Print the cards on card stock and laminate them to make them last longer and stay clean. The graphs are beautiful in color but if you do wish they will print well in gray scale.( black and white, not advised)
Put students in groups or pairs and supply each group with a set of graph cards and a set of inequality cards. Direct them to match each graph with its appropriate inequality and record the letter on the answer recording sheet. Caution them to be careful and alert as some of the inequalities look almost identical but the inequality symbol may be different or it may go downhill instead of uphill, different y-intercept, etc. So even though students are not actually drawing the graphs they must use their analytical skills to determine the correct match by determining whether the border should be solid or dotted, slope indicates uphill or downhill, which side of the border should be shaded, and even to check the y-intercept.
Sounds simple but students really have to use lots of thinking skills to match the graphs. Great review practice for slopes and y-intercepts as well.
The inequality graph cards can be used on their own to have students write the inequality represented by the graph. Works well as a daily Warm Up by projecting a group of 4 graphs each day to have students write the correct inequality represented by each graph.
