What is an easy way to switch content based on checkbox selection?

Newbie question…

I would like to have a page with a checkbox in the top. If the checkbox is selected, a certain set of options are displayed below. If it is not selected, another set of options are displayed below.
What is the easiest way of managing this in Meteor?

The most tutorials use Session as the most simple option for this. You can use the session variable in your helpers and events.

And how to do actual watching.
Create event handler in that checkbox template with something like

'change #checkbox': function(event) {
  Session.set("myCheckbox", event.currentTarget.prop('checked'))
