Rounding

1. Underline the place you want to round
2. Look at the neighbor to the right; circle the digit
3. What does the circled digit tell us? "5 and above, give it a shove" "4 and below, stay low"
4. All digits left of the underlined digit stay the same. All the digits to the right of the underlined digit turn to zeros.

315 rounds to 300

315 - underline the hundreds place

Look next door, circle the 1

( "5 and above, give it a shove", "4 and below, stay low")

Since the neighbor is 1, the 3 stays a 3

All digits to the right of the 3 turn to zeros
