 @group Polymer Core Elements
 
 The `<core-selection>` element is used to manage selection state. It has no
 visual appearance and is typically used in conjunction with another element.
 For example, [core-selector](#core-selector)
-use a `<core-selection>` to manage selection.
+uses a `<core-selection>` to manage selection.
 
 To mark an item as selected, call the `select(item)` method on 
 `<core-selection>`. The item itself is an argument to this method.
 
 The `<core-selection>`element manages selection state for any given set of
 items. When an item is selected, the `core-select` event is fired.
 
 The attribute `multi` indicates if multiple items can be selected at once.
