Make rounding numbers fun with this song. Sing it in repeated form where teacher sings the first line and students repeat it.
Rounding numbers is so fun,
We will do it 'till we're done.
If a number's 1-4,
Round it down right through the floor.
If a number's 5-9,
Round it up it is just fine.
(students respond, 1-2, 3-4)
