Definition: To change with time or a similar parameter.

Alright class, settle in and let’s take a look! You’ve got a tricky word today – “varies.” It’s a lovely word, but it needs a little unpacking, doesn't it? The dictionary is right to say it means "to change with time or a similar parameter." Let’s break that down. “Varies” means something isn’t fixed - it’s not the same all the time. It shifts and changes! Think of it like this: Temperature varies: Sometimes it's hot, sometimes it's cold – it doesn’t stay one temperature. The number of students in a class varies: One day there might be twenty-five, the next day maybe twenty-two! “Parameter” is just a fancy word for something that influences how things change. Like, the weather parameter (the sun, clouds, wind) can affect whether it’s a warm or cold day. So, “varies” means something isn't constant; it has different values depending on what's happening around it. Does that make sense? Now, let’s try an example… Can anyone think of something that varies in our classroom today? (Pause for student responses - encourage them to use the word “varies” in their answers!)
