Word Problem Wednesday: Triceratops Eggs

By Mathnasium | Added Mar 22, 2017

 

The triceratops we know and love was HUGE. This dinosaur could grow up to 30 feet long and weighed as much as a truck! But did you know that triceratops eggs were only about the size of a cantaloupe?

 

This week’s Word Problem Wednesday is as BIG on fun as a nest of triceratops eggs! Give it a try and check back tomorrow to compare your answer with ours. You won’t be “saur-ey”!

 

A paleontologist found five triceratops nests. The first nest had 12 eggs. The second nest had 14 eggs. The third nest had 12 eggs. The fourth nest had 16 eggs. The fifth nest had 21 eggs. What is the average number of eggs in a triceratops nest?

 

Update! Here is the solution:

 

To find the average, we add up all the eggs and then divide by the number of nests.

12 + 14 + 12 + 16 + 21 = 75 eggs. 75 eggs ÷ 5 nests = 15 eggs per nest!

 

Did you reach the same conclusion? How big do you think that nest would be? We figure any nest big enough to hold 15 cantaloupe-sized eggs would have to be almost as big as the bed you sleep in!
