Throwing darts is no easy sport: you aren’t just aiming for the middle of the dartboard the whole time. As you see in this picture, each wedge of the board has a number, which equals the points you score if you throw your dart there – except for the skinny green and red rings, which double or triple those points. Even the bullseye has multiple parts: its outer ring is worth 25 points, but the very center is worth double that (50). To make matters worse, to win a championship you have to score exactly 501 points, and your final throw has to land on the double ring or the double bulls-eye. So darts aren’t just a matter of good aim – you have to do the math right, too.
Wee ones: What shape is the dartboard in the picture?
Little kids: If you throw a 2, a 6 and a 1, how many points did you score? Bonus: If you hit the double ring on the 6, then how many points do you score?
Big kids: If your three darts all hit the 11, but one of them hits the double ring, how many points did you score all together? Bonus: Just as the double ring doubles the points for that wedge, the triple ring triples it. If you hit the triple 13s, what do you score on that dart?
The sky’s the limit: Like a lot of sports and games, darts has its own funny phrases. A “baby ton” means you scored 95 points with three darts. If you scored that by throwing a triple and two singles all of the same number, what number would that have to be?
Wee ones: A circle.
Little kids: 9 points. Bonus: 15 points, because you’d score 12 points for the double 6.
Big kids: 44 points total. Bonus: 39 points.
The sky’s the limit: 19.

Her mom had Laura baking before she could walk, and her dad had her using power tools at a very unsafe age, measuring lengths, widths and angles in the process. Armed with this early love of numbers, Laura went on to get a BA in astrophysics from Princeton University, and an MBA from the Wharton School of Business; she continues to star-gaze today. Laura’s other interests include her three lively children, chocolate, extreme vehicles, and Lego Mindstorms.
