How to delete games/apps on my apple iphone 4 that my son put on?

He is 14 and downloaded these free games on my apple iphone4. I want to take the apps off.

Hold the app down then click the x when you hold it down

Press down on the app you wish to delete after about 5 seconds or so the little square will start shaking and little X's will appear on the squares and press the X on the apps you wish to get rid of

Place your finger on the app you want to delete and hold it until it starts shaking. Release your finger and push the "X".It will then ask you if you are sure about deleting the app, so press delete. Then, if there are anymore, continue to press the "X" and delete. When you are done, press the home button and all will be normal again.

Place your finger on any app for about 5 seconds. They will start shaking & an x will appear at every app. Click the x on the app you want to delete. It will ask you if you want to delete the app & you click delete.

Ok so the apps are on your screen and there boxy. What your going to do is press and hold one app until it shakes. When they shake a X sign will show on the left corner and you then press the X and it will ask if you want to Delet and then say yes! Also just a little tip on IPhones or iPads whatever I object you have, is press the home button twice, and a music theme may show or apps, and to keep your device clean and faster, swipe the bottom of the screen (where the music theme is) and just like you Delet apps, hold them down until they shake, and tap the red negative sign. This will NOT Delet your apps but keep your device nice and fast. Hope I help!
