There may be no such thing as a unicorn, but a narwhal comes close. Narwhals are arctic whales that have a long, spiral tusk sticking out the left corner of their mouths. That tusk is actually a reeeeeeally long tooth that can grow 10 feet long! Unicorn drawings from hundreds of years ago had twisty horns like that, so maybe narwhals gave them the idea for this magical animal. But narwhals aren’t so easy to find, either!
Wee ones: Who’s taller, you or that 10-foot tooth?
Little kids: How much taller than you is that 10-foot tusk? Find out your height to the closest foot! Bonus: A few narwhals have 2 tusks instead of 1. If there are 9 narwhals but 3 of them are double-tusked, how many tusks are there in total?
Big kids: In the summer, narwhals group up by the hundreds. If a group of 600 narwhals has 2 parents and 2 kids in every family, how many kid narwhals are there? Bonus: If your front tooth is just 1/4 inch long, how much longer is the narwhal’s 10-foot tooth? (Reminder if needed: A foot has 12 inches.)
Answers:
Wee ones: The tooth is taller.
Little kids: Different for everyone…subtract your height in feet from 10. Bonus: 12 tusks.
Big kids: 300 kid narwhals, since 1/2 of all the narwhals are kids. Bonus: 119 3/4 inches, or 9 feet 11 3/4 inches.
