From our teachers' playbook

Lines, angles and a protractor party!

What do 4th graders learn about geometry?

Fourth grade geometry gives kids the words for what they see. They learn the difference between a line, a ray and a segment, spot parallel and perpendicular lines, and name angles as acute, right or obtuse. Then out come the protractors! Kids measure and draw angles in degrees, like a right angle = 90°. They also sort shapes by their sides and angles and find lines of symmetry. The click moment is realizing a square is a special rectangle, because it checks every box on the list.

Our favorite ways to make geometry stick

Geometry is all about seeing and naming. These moves get kids drawing, measuring and sorting.

Draw it, name it

Kids draw a line, a ray and a segment, then label them with arrows and dots. "Does it go on forever? Which way?" Making the drawing themselves helps kids remember which one has arrows on both ends.

Why it works: pairing a picture with each word gives kids two ways to remember it, a well-tested principle of how people learn (Mayer, 2009).

Make an angle with your arms

Have kids use their arms as rays: straight up and out is a right angle, closer together is acute, wider is obtuse. Then they measure real angles with a protractor. The body motion makes the names stick.

Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.

Angle flash check

Show an angle and give kids three seconds to call it: acute, right or obtuse? Then estimate the degrees before measuring. Quick checks build the gut sense that catches protractor reading mistakes.

Why it works: researchers who compared ten study methods found practice testing is one of the two that work best (Dunlosky and colleagues, 2013).

Questions parents and teachers ask us

What geometry is taught in 4th grade?

Fourth graders learn points, lines, rays and segments, parallel and perpendicular lines, and types of angles. They measure and draw angles with a protractor, classify shapes by their sides and angles, and find lines of symmetry.

How do I teach a child to use a protractor?

Line up the center hole with the angle's vertex and one ray with the zero line. Then read the number where the other ray crosses. Estimating first, acute or obtuse, helps kids pick the right scale.

What is the difference between a line, a ray and a segment?

A line goes on forever in both directions. A ray starts at a point and goes on forever in one direction. A segment has two endpoints and a set length.

What are parallel and perpendicular lines?

Parallel lines never meet, like railroad tracks. Perpendicular lines cross to make a right angle, like the corner of a window.
