[br]The game aims students to estimate the proximity of the randomly given fractions to the given benchmarks which are 0, half and whole. Students also can get feedbacks about whether their estimation are correct or not.

How can you construct the game?[br][list][/list][br]1.Start with creating a slider[icon]https://www.geogebra.org/images/ggb/toolbar/mode_slider.png[/icon] whose interval is between 1 to 50 and increment is 1.[br][br]2.Go to "Steps" menu and create an input b=RandomBetween(1,50)[br][br]3.Create a second input a=RandomBetween(0,b-1).[br][br]4.Form the third input as Fraction=a/b.[br][br]5.Drag this input with right click[icon]https://www.geogebra.org/images/ggb/toolbar/mode_move.png[/icon] and drop on the main page.[br][br]6.Form a text box(text2) [icon]https://www.geogebra.org/images/ggb/toolbar/mode_text.png[/icon]named as "Response".[br][br]7.Create a button [icon]https://www.geogebra.org/images/ggb/toolbar/mode_buttonaction.png[/icon]whose caption is "Change Fraction".[br][br]8.Create another 3 buttons [icon]https://www.geogebra.org/images/ggb/toolbar/mode_buttonaction.png[/icon]named as "Close to zero", "Close to half" and "Close to whole".[br][br]9.Go to the settings [icon]https://www.geogebra.org/images/ggb/toolbar/mode_tool.png[/icon]of the "Change Fraction" button with right click on it.[br][br]10.In settings, firstly go to "scripting" and then "on click". Write [br]b=RandomBetween(1,50)[br]SetColor(button2,gray) SetColor(button3,gray)[br]Setcolor(button4,gray)    [br][br]11.Right click on the "Close to zero" button, go to settings>scripting>on click. Write [br]If(0<=Fraction<=0.24, [br]SetValue(text2,"That's True!"))[br]If(Fraction>0.24,SetValue(text2,"No"))[br]If(0<=Fraction<=0.24, SetColor(button2,green))[br]If(Fraction>0.24, SetColor(button2,red))[br][br]12. Right click on the "Close to half" button,[icon]https://www.geogebra.org/images/ggb/toolbar/mode_buttonaction.png[/icon] go to settings>scripting>on click. Write [br]If(0.25<=Fraction<=0.74, SetValue(text2,"Great :)"))[br]If(Fraction>0.74 ,SetValue(text2,"Try Again:("))[br]If(Fraction<0.24 ,SetValue(text2,"Think Again"))[br]If(0.25<=Fraction<=0.74, SetColor(button3,green))[br]If(Fraction>0.74,SetColor(button3,red))[br]If(Fraction<0.24,SetColor(button3,red))[br][br]13. Right click on the "Close to whole" button[icon]https://www.geogebra.org/images/ggb/toolbar/mode_buttonaction.png[/icon], go to settings>scripting>on click. Write [br]If(0.75<=Fraction<=1, SetValue(text2,"Congratulations! .)"))[br]If(Fraction<0.74,SetValue(text2,"Sorry"))[br]If(0.75<=Fraction<=1, SetColor(button4,green))[br]If(Fraction<0.74,SetColor(button4,red))[br][br]14. Go to the settings of the "Change Fraction"[icon]https://www.geogebra.org/images/ggb/toolbar/mode_buttonaction.png[/icon] with right click on it. Go to settings>scripting>on click and add SetValue(text2," ")[br][br]15. Now, you can improve design [icon]https://www.geogebra.org/images/ggb/toolbar/mode_copyvisualstyle.png[/icon]of your tool to make it visually attractive if you want :)
