We feel like we can never have enough examples of math in real-world situations. They help keep skills sharp and make sure that we can handle whatever comes our way. This week’s word problems do just that in what we call a “mathematical mixed bag.”

Look below and choose the word problem that’s the right skill level for your child. Have them give it a try. And when they feel they’ve found the answer, check their solution against ours.

Questions

**Lower Elementary:**

*Question:* An octopus lives in an underwater garden shaped like a rectangle. The fence around the garden is 7 feet on the long sides and 5 feet on the short sides. Draw a picture of the garden on graph paper. How many 1-foot squares are in the octopus’s garden, and how many feet of fence go around it?

**Upper Elementary:**

*Question:* John has a manuscript that is 1,040 pages long. If it took him 2 years to write, then how many pages did John write per week on average?

(Hint: There are 52 weeks in a year.)

**Middle School:**

*Question**: *A blackbird starts singing in the middle of the night, exactly between sunset and sunrise. If the sun sets at 5:37 p.m. and rises at 6:47 a.m., then at what time of night does the blackbird sing?

**Algebra and Up:**

*Question:* There is a hole in Paul’s ceiling where rain drips in at a rate of 15 milliliters per minute. As Paul fixes the hole, the rain that gets through decreases linearly. It takes him 2 minutes and 36 seconds to complete the task. How much rain gets in as Paul fixes the hole?

(Hint: Graph the decreasing rate of dripping rain in terms of time. What shape is formed under the graph?)

Solutions

Excellent! Are you ready to check your child’s answer? Look below to see if their solution matches ours.

**Lower Elementary:**

*Answer:* 35 square feet in area, 24 feet in perimeter

*Solution:* If we draw a picture of the garden broken into square feet, it’ll look like this:

If we count the squares, we find that there are 35 square feet in the garden. If we count around, we see that the garden has 24 feet of fence around it.

**Upper Elementary:**

*Answer:* 10 pages per week

*Solution:* If there are 52 weeks in a year, then there are 104 weeks in 2 years. To find the average number of pages John wrote on an average week, we divide 1,040 pages by 104 weeks and get 10. John wrote an average of 10 pages per week.

**Middle School:**

*Answer**:* 12:12 a.m.

*Solution:* First, we need to know how long the night is: there are 12 hours from 5:37 p.m. to 5:37 a.m. and another 1 hour and 10 minutes until 6:47 a.m. So, the night is 13 hours and 10 minutes long. Halfway through the night is (13 hours + 10 minutes) ÷ 2 = 6 hours and 35 minutes after 5:37 p.m., which is 12:12 a.m.

**Algebra and Up:**

*Answer:* 19^{1}/_{2} milliliters

*Solution:* When we graph the rate of dripping rain in terms of time, we get a line whose ** y**-intercept is 15 milliliters per minute and whose
