Eight sets of four three-digit numbers fill this page, with four square boxes beside each set for the answer. Most sets separate cleanly on the hundreds digit, so 314, 152, 428, 236 can be sorted without ever looking at the ones. Two sets do not: 348, 375, 162, 391 and 517, 583, 542, 296 each hold numbers sharing a hundreds digit, which forces a child to move to the tens. A teal and a coral owl perch on a stack of books above the title, inside a beaded teal border.
Those two harder sets are the point of the sheet. A child who has learned “biggest hundreds wins” will fly through six rows and then have to slow down and compare a second digit, which is exactly the habit three-digit comparison needs. Everything else stays deliberately plain, no regrouping and no word problems, so the only thing being practised is reading a number’s place values in the right order. It follows on directly from the two-digit sheet in this set.
