From our teachers' playbook

Big, bigger, biggest fun!

What do kindergartners learn about size?

Kindergartners learn to compare two things and use the right words: bigger and smaller, taller and shorter, longer and shorter, heavier and lighter. They line objects up side by side to check, starting from the same end. Then they order three things from smallest to biggest. The click comes when kids learn that "big" is always compared to something: a dog is big next to a mouse but small next to an elephant!

Our favorite ways to teach size

Size is something kids can hold, stack and see, so we start with real things and add words as we go.

Line it up and check

Hand each child a pencil, a crayon and a block. Ask them to line the ends up on the table edge and decide which is longest. Then they order them. Lining up from the same starting point is the habit that makes later measuring work.

Why it works: kids understand an idea best when they touch it, then draw it, then write it, the order the U.S. Department of Education recommends for elementary math.

Say the size words out loud

Model full sentences: "The giraffe is taller than the dog." Then have partners hold up two classroom objects and say a sentence of their own. Kids who can say it can usually see it.

Why it works: when kids say the precise math words, their understanding gets sharper, a recommendation of the U.S. Department of Education's elementary math guide.

Smallest to biggest on paper

After kids have ordered real objects, move to pictures. Ask them to point and say the order before they cut or color. The jump from things to pictures goes smoothly when the words are already there.

Why it works: children learn more from words and pictures together than from words alone (Mayer, 2009).

Questions parents and teachers ask

What size words should kindergartners know?

Big, small, tall, short, long, heavy and light, plus the comparing forms like bigger, taller and shorter. By the end of the year many kids can also order three objects by size.

How do I teach comparing size in kindergarten?

Start with two real objects side by side, lined up at one end. Ask "Which is longer?" and have kids answer in a full sentence before moving to pictures.

What is a fun size activity at home?

Sort shoes, cups or stuffed animals from smallest to biggest. Kids love lining up the whole family's shoes and finding the biggest one.

Why does size matter in kindergarten math?

Comparing size is the first step toward measuring. Kids who can line things up and compare are ready for rulers and units in first grade.
