Rounding to the Nearest 100 and 1000

Part (a) of this task fits squarely within third grade when students 'use place value understanding to round whole numbers to the nearest 10 or 100'. Part (b) is a first step in rounding beyond tens and hundreds. This task naturally builds off of 3.NBT Rounding to the Nearest Ten and Hundred in third grade. Since fourth graders are expected to 'use place value understanding to round multi-digit whole numbers to any place', this task also naturally builds towards 4.NBT Rounding to the Nearest 1000.
