"The number to the right must be found: Five or more? ROUND UP! Less than five? ROUND DOWN!" You're students will definitely ask you to play this one again. Rounding has never been as engaging as it is in this math song that you'd think could be a pop hit if it was about something other than math. Just hit the arrow, let the video play, and relax while you get ready to take a vacation to the land of rounding decimals and whole numbers.
