Size Ordering Worksheet

Order by Size with Christmas

Preschool Size seriation (readiness) Aligned standard — coming soon

Smallest to biggest! On this pre-K worksheet a child puts Christmas things in order by size, from the smallest up to the largest. Arranging the whole set in a size sequence — working out which a tree, a bauble and a stocking comes next as the row grows — asks a child to hold the order in mind, not just compare a pair. Building the size row, end to end, is ordering at its most concrete, with no numbers involved.

Before a child orders numbers, they can order sizes — and arranging things smallest to biggest is sequencing at its most concrete. Lining up Christmas things by size asks a preschooler to build a whole ordered row, deciding what comes next as it grows. That sequence-building is a step up from a two-way comparison, and the child grows it by arranging the row from one end to the other.

Children love building a neat row that climbs from smallest to biggest, and finishing the size order feels satisfying. When this is easy, put the sizes in order in order by size with classroom objects, or try order by size with dinosaurs. You can also browse every size-ordering worksheet or the whole preschool collection — each sheet prints cleanly or plays online for free, and the more a child orders things by size, the surer their sense of sequence grows.
