Cassie is trimming her pet's nails. She has four dogs and eight parrots. Each dog has four nails on each foot, and each parrot has three claws on each leg, except for one parrot who has an extra toe. How many nails does Cassie need to cut?
Answer: 113First, find the number of dog nails by multiplying the number of dogs by the number of nails on each leg and the number of legs on each dog: 4 dogs * 4 legs per dog * 4 nails per leg = 64 nails. Then do the same for parrots, ignoring the one parrot's extra toe for now: 8 parrots * 2 legs per parrot * 3 nails per leg = 48 nails Now add one to the previous number because one parrot has an extra toe: 48 + 1 = 49 nails. Now add the number of nails from the parrots and the dog: 49 nails + 64 nails = 113 nails.

Bob is tilling a plot of his garden. The plot is 110 feet wide by 120 feet long. His tiller digs a swath two feet wide, and he can till 1 foot of ground in about 2 seconds. How long will it take him to till this plot of land, in minutes?
Answer: 220If Bob goes along the side that's 120 feet long, he will till 110 / 2 = 55 rows. Each of these rows are 120 feet long, so he will push the tiller a total of 120 * 55 = 6,600 feet. He tills 1 linear foot of ground every 2 seconds, so it will take him 2 * 6,600 = 13,200 seconds to till this plot 13,200 seconds is 13,2000 / 60 = 220 minutes

Three times the sum of marbles that Atticus, Jensen, and Cruz have is equal to 60. If Atticus has half as many marbles as Jensen, and Atticus has 4 marbles, how many marbles does Cruz have?
Answer: 8Three times the sum of marbles that Atticus, Jensen, and Cruz have is equal to 60, meaning together they have 60/3=20 marbles. If Atticus has half as many marbles as Jensen, and Atticus has four marbles, Jensen has 2*4=8 marbles. Together, Atticus and Jensen have 8+4=12 marbles. Since the sum of marbles that Atticus, Jensen, and Cruz have is equal to 20, and Atticus and Jensen have 12 marbles, Cruz has 20-12=8 marbles.

Alissa used discarded paper to make notepads for her friends. She would fold 5 pieces of letter-size paper 3 times then cut along the edges to form smaller note papers. She would then stack these smaller note papers and staple them together. How long would 1 notepad last if someone wrote 10 notes per day?
Answer: 4Alissa folding it 3 times makes 2 × 2 × 2 = 8 pieces of note-size paper per letter-size paper. So 5 pieces of letter-size paper make 5 × 8 = 40 pieces of note-size paper. 1 note pad would last 40 ÷ 10 = 4 days if someone wrote 10 notes a day.

Big Dig Mining Company mines three different types of ore: copper, iron, and nickel. Across all their mines, 10% of their output is nickel, 60% is iron, and the rest is copper. They mine 720 tons of nickel a day. How many tons of copper does Big Dig Mining Company mine daily?
Answer: 360Let R be the total ore output of the company. Of Big Dig’s output, 100 - 10 - 60 = 30% is nickel. Since 720 is 60% of 100% of their output, 720 / R = 60 / 100. Thus, Big Dig mines R = 100 * 720 / 60 = 1200 tons of ore daily. Therefore, Big Dig mines 1200 * 30 / 100 = 360 tons of copper daily.

Mark went to a store where he spent one-half of his money, and then spent $14 more. He then went to another store where he spent one-third of his starting money, and then spent $16 more. If he then had no money left, how much did he have when he entered the first store?
Answer: 180Let X be the money Mark had. Mark spent 1/2*X + 14 in the first store and 1/3*X + 16 in the second store. Mark has X - 1/2*X - 14 - 1/3*X - 16 = $0 left. Combining like terms, we get 1/6*X - 30 = $0. Adding 30 to both sides and multiplying both sides by 6, we find that Mark had X = $180 when he entered the first store.

Eliza can iron a blouse in 15 minutes and a dress in 20 minutes. If she spends 2 hours ironing blouses and 3 hours ironing dresses, how many pieces of clothes did she iron?
Answer: 17Since 60 minutes equal 1 hour, in 2 hours, Eliza ironed blouses for 2 x 60 = 120 minutes. Eliza can iron 120 / 15 = 8 blouses. Since 60 minutes equal 1 hour, in 3 hours, Eliza ironed dresses for 3 x 60 = 180 minutes. Eliza can iron 180 / 20 = 9 dresses. In total, Eliza ironed 8 + 9 = 17 pieces of clothes.
How to use these math word problems
- Think-pair-share. Give one problem, two minutes alone, two minutes with a partner, then compare methods as a class.
- Estimate first. Before solving, ask for a quick estimate. Comparing estimate and answer builds number sense.
- Show the steps. Reveal the worked solution only after students share theirs — then discuss the differences.
