Q: When does a teacher carry birdseed?
A: When there is a parrot-teacher conference!
This week’s word problem is tweet-tastic! Practice your elementary school math skills such as weights and measures, addition, subtraction, and fractions as you figure out how many robins one nest can hold. Take a step back, get a bird’s-eye view, then have some math fun figuring out the solution! When you think you have it, look below to check your solution against ours.
Challenge: A robin builds its nest out of 1/8 of a pound of grass, 1/8 of a pound of twigs, and 1/8 of a pound of mud. The robin weighs 3/16 of a pound. Its clutch of 4 eggs weighs an ounce. How many ounces does the nest weigh with all of its occupants inside?
Solution: A pound is 16 ounces. So, an ounce is 1/16 of a pound. The nest weighs 1/8 + 1/8 + 1/8 = 3/8 = 6/16 of a pound, or 6 ounces. The robin weighs 3/16 of a pound, or 3 ounces. The 4 eggs weigh another ounce. So, the nest and all its occupants weigh a total of 6 + 3 + 1 = 10 ounces.
