Mathematics: Grade 3: Number & Operations in Base Ten
Use place value understanding and properties of operations to perform multi-digit arithmetic. (A range of algorithms may be used)
3.NBT.1. Use place value understanding to round whole numbers to the nearest 10 or 100.
Rounding Rap
Find the place value and
Circle that digit.
Move to the right
And underline, get it?
Zero to four
Circle stays the same,
Five to nine
Add one is the game.
Now, flex your muscles
Like a hero,
Digits to the right
Change to zero.
All the other digits
Remain the same.
Yo! You're a winner
In the rounding game!
