Dog on Wheels

November 17, 2017

The skateboard is such a cool, simple toy: a board with wheels under it. You just stand on it while pushing against the ground with one foot, and you can roll really fast. People do all kinds of tricks on skateboards, including flipping the board, riding down handrails, and other stunts. But it’s even more exciting when it’s a dog doing the tricks. A bulldog in Lima, Peru named Otto set the world record for the longest ride on a skateboard through a human tunnel. 30 people stood in a line with their legs spread apart, and Otto rolled through all those Vs. It all started with an accident, when Otto was riding on his skateboard at full speed towards his owner. She jumped up and let him zoom between her legs. A tunnel of 30 people is much trickier, but Otto may want to break his own record, so watch out!

Wee ones: If a skateboard has 2 little wheels in the front and 2 in the back, how many wheels does it have?

Little kids: If you counted off those 30 tunnel people in sets of 10, what numbers would you say? Bonus: In 2015 when he set the world record, Otto was 3 years old. In what year was he born?

Big kids: If you’re one of the 30 people helping Otto, how many people are making the tunnel with you?  Bonus: How many legs do Otto and those 30 people have all together?

The sky’s the limit: If every 3rd person starting with the 3rd patted Otto’s head and every 4th person starting with the 4th slipped him a doggie treat, how many of the 30 people patted him but didn’t give him a treat?

 

 

 

Answers:
Wee ones: 4 wheels.

Little kids: 10, 20, 30.  Bonus: In 2012.

Big kids: 29 people.  Bonus: 64 legs, since the people have 60 and Otto has 4.

The sky’s the limit: 8 people. 10 people patted him, but 2 of those people also fed him (the 12th and 24th).
