Bull’s-Eye!

Bull’s-Eye!

July 21, 2020

Archery is an exciting sport, partly because it’s dangerous. The archers take a bow — a long, curved stick with a string stretched across it — and pull back a pointy arrow on that string. When they let go, the arrow flies through the air at about 150 miles an hour, while the rest of us run to get out of the way. The archers aim at a flat circular target 77 yards away (1 yard is 3 feet). The target has 10 colorful rings, and the closer to the “bull’s-eye” your arrow lands (the very center), the more points you get! That gold circle in the middle scores 10 points, the next circle around it scores 9, and so on until the white ring on the edge, worth just 1 point. The better your aim, the faster the math adds up.

Wee ones: Circles inside each other that share the same center are called “concentric.” Can you find a circle inside another circle on anything in your home?

Little kids: If you shoot an arrow into the 6 ring and the next into the 8 ring, what number ring did you skip? Bonus: If you shoot 6 arrows and they all hit the bull’s-eye, which is worth 10 points, how many points do you score in total? Count up by 10s!

Big kids: In a game, each archer shoots 12 “phases” of 6 arrows each. How many arrows does the archer shoot in a game? Bonus: How many ways can 3 arrows add up to 26 points? Remember, each arrow scores between 1 and 10 points (and don’t worry about the order, just the sets of numbers.)

 

 

 

 

 

 

 

 

 

 

Answers:
Wee ones: Items might include an on/off button, a button on clothes, the bathtub drain, the inner and outer edges of a donut…or a shopping bag from Target!

Little kids: The 7 ring. Bonus: 60 points: 10, 20, 30, 40, 50, 60.

Big kids: 72 arrows. Bonus: There are only 4 ways, since the lowest number has to be at least 6 (since the other 2 rings can add to 20 at most). The combinations are 6, 10, 10;  7, 9, 10;  8, 8, 10; and 8, 9, 9.
