This is the HTML code used to create a radio button:

<form name="form">
<input type="radio">
</form>

The form tag lets the computer know you'll be using forms and the input tag can be used for many different thing. In this case, since I specified the type as radio, it will produce a radio button.

As you can see it does absolutely nothing. Thats because radio buttons need JavaScript to be able to work. We will learn how to use radio buttons in the next few lessons.

Another very useful form is the button, we will be using this later to check the answers. This is how you make a button:

<form name="form" onSubmit="return false;">
<input type="button" value="Submit">
</form>

I just changed the type to button and added "onSubmit="return false;"" in the form tag, the reason for this is that if you don't add that the page will be reloaded whenever you press the button and the students answers will be cleared. Value is used to write something on the button so the user can know what it is for.
