Putting things in order by size is one of the first measuring skills. Every row on this sheet shows one picture three times — an elephant, an apple, a balloon — in a small, a middle and a big size, mixed up. The child looks at all three, finds the smallest and writes 1 next to it, then 2 next to the middle one and 3 next to the biggest.

Set Order to Small to big, or to Big to small to count down from the biggest instead; the title and the instructions on the sheet change with it. Choose four, five or six rows on a page. Every picture on a page is different, and a row is never already in order.

Press New sheet for new pictures. The answer key prints on a second page only when you ask for it. Every sheet prints in color or black and white, on US Letter or A4. Nothing to sign up for.
