Each stroke is one. Four vertical strokes, then a fifth that slashes diagonally across the four — that's a "five-bar gate," a complete group of five. To find the total: count the completed gates, multiply by five, then add any leftover vertical strokes still on their own.
Most people can take in a group of four or five marks at a glance, without consciously counting — psychologists call this subitizing. Past five, the brain has to count one by one, which is slower and more error-prone. Bundling tallies into fives lets your eye do most of the work: count the bundles, glance at the leftovers, done.
It's the same reason your hand has five fingers and most cultures' first counting systems used base-5 or base-10 — the size of the grouping matches the size of a single mental snapshot.
People have been making single-stroke counts on bones, sticks and walls for at least 20,000 years. The Ishango bone, found near Lake Edward in central Africa, has rows of notched marks that look a lot like Stone Age tally counting.
The specific four-strokes-plus-a-diagonal-slash form is younger. In 18th-century England, it was called the "five-bar gate" — named for the wooden farm gates English shepherds, tax collectors, and pub landlords used as visual references when counting sheep, bushels of grain, and customers' tabs. The shape was so common in everyday counting that it survived two centuries of mechanical calculators and now lives on as the way we still count quick, by-hand totals: pitch counts, bird species, lap counts, attendance.
\; drag down-left and it leans like /.For young counters: This is a great way to practice counting past ten without losing track. Draw one stroke for every thing you're counting — claps, jumps, books, anything. When you finish a gate of five, you've got a snapshot you can read at a glance. Two gates and three loose strokes? That's 5 + 5 + 3 = 13.
A tally mark is a single stroke that stands for one count. Four vertical strokes plus a diagonal slash across them make a group of five — the "five-bar gate." Read the tally by counting completed gates of five plus any extras.

Swipe (or click and drag) anywhere on the chalkboard to draw a tally line. The first four swipes draw vertical strokes, left to right. Your fifth swipe draws the diagonal slash through them, completing a group of five — and that group slides into the bundle row below. The slash leans in the direction your finger moved.
Yes — tally marks are how kindergarten and early-elementary classrooms introduce counting beyond ten. Drawing the strokes by hand reinforces one-to-one correspondence, and the visual "gate of five" makes skip-counting (5, 10, 15, 20…) feel natural before kids meet multiplication.
