1.You need to click the button of the new problem to start a new game. 2.Your target is matching the points A and B with the given numbers in the inequalities. 3.Thus, you wiil show the inequalities on the numberline by moving the AB segment on the numberline. 4.If you move it on the right point, you will see the feedback. 5.Now try to do this till you see the feedback. 6. You can repeat this process when you want to begin with new game.

M.8.2.3.2. Birinci dereceden bir bilinmeyenli eşitsizlikleri sayı doğrusunda gösterir.x ≥ -1, -3 ≤ t < 7, a < 1 gibi durumlar inceletilir. [list=1] [*] 1. Hide the y axis from the y axis part of the settings. 2. Choose the distance 1 cm from the x axis part of the settings. 3. Choose the snap to grid from the set point capture style. 4. Put wo point A(-2,1) and B(2,1). 5. Construct the segment with A and B points. 6. Choose the circle from the set point style because this is for a < x < b inequalities. 7. Put the points C and D. These are should have random apsis and 0 ordinate. C=(Rastgele(-10,5),0) D=(Rastgele(6,10),0). You can choose any interval what you want. 8. Construct variable a which is equals to apsis of C and b which is apsis of D. a=x(C) and b=x(D). 9. Add the text and write the “Show on the number line!” on the definition part. 10. Add another text and write “a < x < b” Choose the “a” and “b” from the logo of Geogebra part including variables. 11. Add one more text and write “Right!”. Click right and go to settings and advanced part write the condition (A ≟ C ∧ B ≟ D) on the condition of the showing object. 12. Add and image from the image button and Click right and go to settings and advanced part write the condition (A ≟ C ∧ B ≟ D) on the condition of the showing object. 13. Hide C and D on the number line. 14. You can arrange your background color and text style whatever you want from the settings. 15. This procedure is for the interval of a < x < b inequalities and we create tree more game for the other inequalities such as “≤-<”,”≤-≤”,”<-≤”. You can change the some parts such as interval of the points and point style for the other inequalities. [/list]
