From our teachers' playbook

Circles, squares and shape surprises!

What do 1st graders learn about geometry?

First graders learn what really makes a shape a shape. A triangle is a triangle because it has 3 sides and 3 corners, not because it's blue or big. They put shapes together to build new ones, like two triangles making a square, and they meet solid shapes like cubes, cones and cylinders. They also cut circles and rectangles into equal halves and fourths. The click comes when a 1st grader builds a house out of shapes and names every piece!

Our favorite ways to make geometry stick

First graders learn shapes by touching, building and singing. Here's what works for us.

Put shapes together

Hand out paper shapes and say, "Can you make a rectangle with two squares?" Kids slide and flip pieces until it works, then glue them down. Building composite shapes shows them shapes can hide inside other shapes.

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.

Sing the circle

Start shape time with a short shape song and have kids trace a circle in the air with their finger. Singing the same song a few days in a row locks in the name and what makes it round.

Why it works: a catchy, repeating tune gives the brain a hook to hang words on, so sung text is remembered better (Wallace, 1994).

Shape sort showdown

Mix a pile of shapes in different colors and sizes. Kids sort them by number of sides as fast as they can. Ask "Why is the tiny red one in the triangle pile?" to check they're sorting by sides, not color.

Why it works: pulling an answer out of memory makes it stick far better than rereading it, one of the strongest findings in learning research (Dunlosky and colleagues, 2013).

Questions teachers and parents ask

What shapes should a 1st grader know?

First graders should know circles, squares, rectangles, triangles and trapezoids, plus solid shapes like cubes, cones, cylinders and spheres. They should also tell which features make each shape what it is.

What are composite shapes in 1st grade?

A composite shape is a new shape made by putting smaller shapes together. Two triangles can make a square, and a square plus a triangle can make a house.

How do I teach shapes to a 1st grader at home?

Use snacks! Crackers, cheese slices and sandwiches come in lots of shapes. Have your child name each one, count its sides, and cut it into halves.

Do 1st graders learn halves and fourths?

Yes. First graders split circles and rectangles into two or four equal parts. They learn that more pieces means smaller pieces.
